USER GUIDE

PRODUCT DESCRIPTION

WebVision™ is a web-based building manager that allows
contractors and facility managers to view and command
HVAC controllers installed at their sites. It communicates over
the LonWorks
control of various devices and controllers through a web
browser. The WebVision Bundle (WWS-VL1A1000) includes
the WebVision controller pre-installed with a LON
communications card, and power supply.

WebVision is capable of:

• Discovering unitary controllers connected to WebVision

• Configuring controllers using configuration wizards

• Monitoring, raising, and e-mailing alarms on controller
points and system events

• Configuring and collecting trends on points

• Driving scheduled occupancy states

• Managing energy through Demand Limit Control (DLC)

• Providing single point of entry into the system to perform all
the above mentioned tasks.

• Managing access to information through user privileges

• Providing IT-friendly network interface for easy access and
management

WebVision acts as an offline configuration tool that helps the
contractor to configure site project that consists of multiple
unitary controllers. The contractor can commission all the
controllers by connecting through a LAN, WAN, or Dial-up.

WebVision also acts like a network time master to synchronize
time and date in devices connected to it with its own time and
date or with the Internet time servers. Its Device Discovery
feature enables you to discover online devices. You can
manage users and control their access to different resources
in the system. The System Administrator can configure
network settings, site information settings, system and control,
network data and time settings, and new module installation.

Alarms

Viewing alarms

A device configured with alarm settings is set when the value
of a point satisfies the alarm condition of that device.

Use the Alarms tab to view and acknowledge alarms that are
raised on various devices. You can filter alarms based on
occurrence, acknowledgment status, ack time, RTN time,
priority, and so on. You can setup alarms, define their limits,
and prioritize them. You can also acknowledge alarms and
delete acknowledged alarms.

Alarm priorities can be set for each type of alarm condition.
The alarm priority can range from 1 to 10 and is used to
determine E-Mail alarm message recipients. High priority
alarms have a higher reporting priority. For example, system
alarms (for example, low battery) are always high priority.

E-Mail alarm messages can be sent to a maximum of 50 E­Mail addresses. Any E-Mail alarm message can be sent to

Users

You can create a maximum of 30 user profiles. You must be
familiar with User ID and Password security standards to
enforce user compliance when creating a user profile. As
WebVision is a secure server, you need to log in with a pre­assigned user ID and password. The user ID and password
combination determine your access level, which in turn
determine the kind of operator and configuration functions
performed.

The Network Administrator must be familiar with user ID and
password security standards and enforce user compliance.
The WebVision System Administrator can be accessed using
these initial default user ID and password: User ID ­SysAdmin and Password - !Sys!Admin.

It is a good practice to add one or more additional users with
Administrator access level to ensure top level access to
WebVision. Those with higher access levels have the
privileges of all the lower levels in addition to the privileges
unique to that level. These access levels are managed by the
System Administrator. There can be an individual or many
System Administrators who are assigned the task of
managing individuals at different access levels.

NOTE: For security compliance, it is mandatory to change

Use the Users tab to add users, assign devices to them and
define their privileges based on their roles. There are four
types of user roles (see Table 3):

• Contractor - Contractor is a user with all the privileges

• Facility Manager - This role represents a Building

• Tenant - The user assigned to this role has limited access

• Balancer - Balancer is a user who performs VAV Balancing

Demand Limit Control (DLC)

Demand Limit Control (DLC) continuously monitors the
building's rate of energy consumption. It automatically sheds
or restores loads to prevent the demand (load) from
exceeding the maximum allowable level or configured
setpoint. It is based on the building's power requirements and
operating characteristics. For DLC to have control over
energy savings, the configured setpoint must be less than the
actual demand allocated by the power generating plant. DLC
sheds or adjusts the loads during peak usages only. DLC is
driven from the current KW demand, which is an
instantaneous value averaged over a period of time (demand
averaging window period). It is a good practice to adjust the
DLC window close to the utility company's demand window
period. This in turn will help WebVision to follow the same
criteria as that of the utility company when taking KW demand
shed decisions. The energy history log must also match the
peak demand recorded by the utility company.

Load Assignments

Each device is considered to be an external object when
assigning it to a load. A load consists of a local configuration
that defines the behavior of the load and its association with
an object or a set of objects. These objects are discovered
Excel 10 or Excel 15C devices, which in turn control the
external electrical loads. All the objects associated under one
load assignment are shed at once, restored at once and
overwritten at once depending on the configuration of the load
assignment. Each load assignment is identified by a load
assignment number ranging from 1 to 50.

The following are the two types of loads that DLC sheds to
maintain demand below the peak setpoint:

Off Continuous Loads

Off Continuous loads are the first loads that are shed by DLC.
Once shed, they are not restored immediately. Loads marked
as Off Continuous generally control the loads that are least
important to overall operation of the facility. When KW
demand exceeds the peak setpoint, Off Continuous loads are
shed first starting from the lowest numbered load (1) to the
highest (50). These loads are shed until the demand goes
below the peak setpoint limit. The first load is shed at staging
interval seconds after the KW exceeds the peak setpoint.
Additional loads are shed at staging interval, seconds until the
KW is less than the peak setpoint. Off Continuous loads, once
shed are the last to be restored when demand is less than the
normal level (setpoint minus the dead band). Off continuous
loads are restored in the order reverse to which they were
shed (highest load (50th) is restored first). Any Off Continuous
load that is shed remains inactive for at least the configured
Minimum Shed Time.

Rotating Loads

Rotating loads are shed or adjusted after shedding Off
Continuous loads, as DLC needs to reduce the demand.
Loads marked as Rotating have more important equipment
assigned to them than the loads marked as Off Continuous.

Rotating loads are shed or adjusted only after all the Off
Continuous loads are shed and if the KW demand still
exceeds the peak setpoint. DLC sheds the Rotating loads in
sequence starting with the lowest numbered load first. When
demand is below the normal level (peak setpoint minus the
dead band), the Rotating loads are restored on a priority
basis; highest priority is given to the load that has been shed
for the longest period. If restoration of a Rotating load causes
KW to raise above the peak setpoint, then the next eligible
Rotating load (usually the next higher numbered Rotating
load) is shed.

NOTE: Note: Rotating loads are restored before Off

Continuous loads when KW demand is below the
normal level (less than the peak setpoint minus the
dead band).
Rotating loads are not eligible for shed until their
Minimum On Time has elapsed after restoration.
Once shed, a Rotating load cannot be shed again
until all the other eligible Rotating loads are shed.
Rotating loads are not restored until their Minimum
Shed Time has elapsed.
Rotating loads can't be in Shed time not more than
the Max Shed time.

DLC Load Shedding and Restoring Methods

DLC monitors the current KW levels at every staging interval
and averages it over a period of time.

• If the current KW demand is above the configured peak
setpoint, then DLC sheds loads at defined intervals until
the demand drops below the peak setpoint.

• If the KW demand drops below the normal level (peak
setpoint minus the dead band), then the previously shed
loads are actively restored at every staging interval until
the KW demand rises back above the normal level.

21 95-7769—01

WEBVISION™

Load Shedding Method

1. The DLC starts shedding by first searching for all the Off
Continuous loads that are eligible for shedding.

2. Then, it first sheds the lowest numbered Off Continuous
load and waits the staging interval to see if the demand
has reduced.

3. If the demand is still above the peak setpoint, then DLC
sheds another Off Continuous load. This process
continues until the demand is well within the peak
setpoint limits.

4. If the demand has still not reduced, then DLC searches
for all the Rotated loads.

Load Restoring Method

• If the demand drops below the normal level, then the loads
that are currently shed will be actively restored one at a
time, every staging interval, until the demand reaches the
normal level. When restoring loads, DLC, on priority,
searches and restores:

• The Rotating loads where the load that has been shed
for the longest period is restored first.

• Then the Off Continuous loads where the load
restoration goes from highest load number to the
lowest load number.

• Loads are restored every staging interval if the override
condition becomes true or the maximum shed time has
been met. All loads that satisfy these conditions are
restored.

Use one of the following filter options to search for the
required load assignment:

• Load Name Pattern

• Shed Method

• Shed State

NOTE: To quickly search, type the first letter of the required

filter criteria in the Keyword text box and type an
asterisk (*). This lists all the names starting with the
first letter that you have written in the Keyword text
box.

DLC Status

Demand Limit Control is a function that controls the maximum
power demand made on the whole system by shedding some
of the load based on priority where total power usage of
configured loads exceeds the predefined limit. Shedding
requires turning off some digital output, or changing a setpoint
to a more economical level.

You can view the DLC service status that includes all load
assignment details. DLC status is updated at the rate of the
staging interval.

Migration of LCBS Sites in WebVision

Ensure that the site configuration backup is available in
LonSpec.

You should use either LonSpec or WebVision as the primary
configuration tool. Having more than one tool would require
effort to keep them in sync that is manual and error prone.

At certain sites where XL15B is installed, the most current
LonSpec database is present on the XL15B. Such databases
must be brought into LonSpec and used for migration.

Device Configuration Changes

Device configuration covers seven areas:

1. ”Decommissioning XL15A”

2. “Decommissioning XL15B” on page 30

3. “Decommissioning T7300” on page 30

4. “T7350 Changes” on page 30

5. “XL15C changes” on page 30

6. “LONSpec Changes” on page 32)

7. “WebVision Configuration Steps” on page 32

Decommissioning XL15A

Following are the considerations for de-commissioning XL15A
(W7760A):

1. Alarms – Alarms in XL15A cannot be automatically
transferred to WebVision. Looking at the XL15A
configuration in LonSpec, manually create
corresponding Alarms configuration in WebVision.
Follow the steps given in User Guide or Online help to
understand how to create Alarms in WebVision.

2. Trends – Trends in XL15A cannot be automatically
transferred to WebVision. Looking at the XL15A
configuration in LonSpec, manually create
corresponding Trends configuration in WebVision.
Follow the steps given in User Guide or Online help to
understand how to create Trends in WebVision.
WebVision comes loaded with default trends for each
type of supported device in disabled state. If the trend
that has to be created is already present and meets the
requirement, the user is advised to just enable that
trend instead of creating a new one.

3. Schedules – Looking at the XL15A configuration in
LonSpec, manually create corresponding Schedules
configuration in WebVision. Follow the steps given in
User Guide or Online help to understand how to create
Schedules in WebVision.

4. Loops – WebVision does not support inbuilt loops.
However, if this feature is critical, the user can replace
XL15A with XL15C. Or the user can disconnect XL15A
from the Lon Network. If XL15C is used, the same loops
can be configured in XL15C using LonSpec and re­commissioned. If the XL15A is disconnected from
network, the user should be aware that it may be driving
RIOs or may have bindings with other devices to get
some sensor information. The device should be
reconfigured and re-commissioned using LonSpec to
remove such dependencies.

5. Network Time Master – If XL15A is acting as Network
Time Master, when decommissioned, WebVision can be
configured to act as Network Time Master. Refer
WebVision’s User Guide or Online Help for details.

6. DLC – If XL15A is performing Demand Limit Control
(DLC). The same can be done in WebVision. However
the user should note that WebVision supports only one
Setpoint. The configuration has to be done as
appropriate. Refer WebVision’s User Guide or Online
Help for details.

7. Pulse Meter Input – If a Energy Pulse Meter is
connected to XL15A because it is running DLC or
because it is providing that information to a different
XL15A, then if replacing XL15A with XL15C will allow
the user to configure XL15C to connect Pulse Meter and
act as source for KW input for DLC running in
WebVision.

29 95-7769—01

WEBVISION™

8. Alarm Dial-Out – This feature is not supported by
WebVision or by any alternate mechanisms. Hence this
has to be dropped as part of migration process.

9. Runtime Logs - This feature is not supported by
WebVision or by any alternate mechanisms. Hence this
has to be dropped as part of migration process.

10. Bindings between XL15A and RIOs – XL15A can be
replaced with XL15C to drive the loops configured. If the
loops are driving RIOs, the same be achieved using
XL15Cs and RIOs. The user should replace XL15A with
XL15C, configure the same loops in XL15C, associate
RIOs to XL15C in LonSpec and re-commission XL15C
and RIOs.

NOTE: The user should remember that replacing a controller

would involve rewiring and testing the physical
installation. The new XL15C that is replacing existing
XL15A has to be purchased separately and will not
be provided along with WebVision.

Decommissioning XL15B

WebVision supports most of the functionality of XL15B.
However XL15B configuration has to be manually created in
WebVision. Configuration of the following functions should be
recreated in WebVision:

1. Alarms

2. Trends

3. Schedules – Unlike in XL15B, WebVision does not

support year round schedules. WebVision supports
weekly schedules that repeat through out the year.
Hence the schedules should be modified accordingly

4. DLC – Note that WebVision supported only one
Setpoint as against three in XL15B. Configuration
should be done accordingly

5. Special Graphics – Special Graphics in XL15B can be
created as Locations and Graphics on Locations in
WebVision

6. Network Time Master functionality

7. Internet Time Synchronization

8. Alarm Emailing

9. User accounts

10. Home Page graphics and Login Page graphics

Decommissioning T7300

Following are the considerations for de-commissioning
T7300:

1. If the devices on the Lon network are following schedule
in T7300, then a similar schedule should be created in
WebVision and assign those devices to follow schedule
created in WebVision. The schedule configuration can
be referred in LonSpec and has to be manually created
in WebVision.

2. If T7300 is acting as Network Time Master, the Network
Time Master Functionality in WebVision has to be
enabled. Once enabled, WebVision will synchronize the
clocks on all supported devices with Real-Time Clocks
that can be updated over the Lon network

T7350 Changes

WebVision supports configuration and management of T7350:

1. If a T7350 exists at the site and is driving scheduled
occupancy state of other devices, the user should
ensure that none of the schedules in WebVision drive

the occupancy state of those controllers that are
following T7350. If WebVision has to drive the
occupancy state of those controllers, user should first
unassign them from T7350 in LonSpec, commission
T7350 and the assigned controllers before configuring
schedules in WebVision

2. If T7350 is acting as Network Time Master, it has to be
disabled from LONSpec and re-commission T7350. The
Network Time Master Functionality in WebVision has to
be enabled. Once enabled, WebVision will synchronize
the clocks on all supported devices with Real-Time
Clocks that can be updated over the Lon network

XL15C changes

XL15C is supported in WebVision. However, there are some
differences that should be noted (below):

1. LonSpec creates bindings between XL15Cs and
assigned RIOs as shown in ‘refer points’ screen. These
bindings are present to read/command all I/Os on RIO
even if they are not used. WebVision does not have
concept of associating RIOs with XL15Cs. Therefore,
following is the behavior during migration:
a. When the XL15C bindings are uploaded in WebVi-

sion, only used/ configured bindings are actually
shown and bindings on un-configured I/Os are
ignored

b. LonSpec allows naming I/Os of RIO (W7761).

These names are stored in associated XL15C’s sec­ondary configuration file. As WebVision does not
support this file, all the RIO point names will appear
with default names in WebVision after migration.
User would manually associate them by creating
appropriate bindings between XL15Cs and RIOs.

2. If an XL15C controller at the site uses a poll point
configured to poll an unsupported LON device, the
Device, NV and Field information will not show up in
WebVision’s XL15C configuration wizard as the device
is not present in WebVision’s database. As part of de­commissioning the unsupported device, the user has to
re-commission the XL15C so that information is
removed from the configuration

3. The time taken to upload/download XL15C depends on
the number of loops configured in that XL15C. If more
number of loops is configured, WebVision will take more
time to upload/download. XL15C stores each loop
configuration in separate sections in its memory.
WebVision while uploading reads general device
configuration, reads the number of loops, reads I/Os
configured and then uploads configuration of each loop
and I/O

4. WebVision will upload all the objects that are configured
and used in control logic. If there are any Math
Functions, Setpoints, Logic Loops, Start Stop Loops that
are just given names or engineering units but do not
read any input or drive any output, such objects may be
ignored. The same reason is applicable while
downloading from WebVision. This optimizes the
download/upload process and does not impact the
XL15C configuration.

5. While uploading bindings, WebVision will not upload
bindings in which unconfigured objects like Control
Loops, Start Stop Loops, Logic Loops, Analog Inputs
are acting as source or target of the bindings.

WEBVISION™

LONSPEC METRIC VALUES

LonSpec downloads metric values to the controller.
WebVision does not do any unit conversion of XL15C
configuration values when displaying in the user interface.
Therefore, what the user gets to see is what is present in the
controller. The following step eases the comparison process:

1. Before comparing XL15C configuration with LonSpec,
right click on the project and open Edit Project dialog as
shown in Fig. 43. Change the Engineering Units to
Metrics before proceeding further.

To fix the configuration error, use the following procedure:

1. Open the configuration of each XL15C and go to
Control Loops tab.

Fig. 44. LONSpec Configuration Screen.

2. Select Loop 6 (clDATLowLim) in control loops and click
Control Params. The Control Loop Parameters

dialog box appears.

Fig. 43. Edit project.

This ensures that you see all the values in LonSpec in the
Metric system.

FIXING RAPIDZONE CONFIGURATION ERRORS IN
LONSPEC

Due to a configuration error in RapidZone, sites built in
Rapidzone and migrated to LONSpec may have a
configuration error for every XL15C controller (W7760C). As a
result, device upload step in WebVision causes problems.

Fig. 45. Control Loop Parameters dialog box.

3. Select an appropriate option for Analog Limit Select
and click OK.

4. Repeat the above steps for all the XL15Cs.

5. After changing the Analog Limit Select, re-commission

all the XL15Cs with LONSpec.

31 95-7769—01

WEBVISION™

LONSpec Changes

Complete the following steps for migrating the existing LCBS
sites to WebVision:

1. Ensure that LonSpec database which is used to
commission the site is ready. Open the LonSpec project.
Click Network > Edit on the menu bar. The Edit

Network dialog box appears.

Fig. 46. Edit Network dialog box.

2. Click Advanced Features. The Advanced Features

dialog box appears.

NOTE: When re-commissioning, please use full commission

command, not quick commission.

6. After re-commissioning, disconnect LonSpec from the
network.

WebVision Configuration Steps

Start the migration process on a fresh WebVision without any
existing config file. There should not be any devices present in
WebVision

1. Configure WebVision as given in the Quick Start Guide
and connect it to Ethernet and LON network.

2. Logon to WebVision through internet browser.

3. Click System > Network Setup. In Channel Info, set

the Domain ID to the same domain ID configured in
LonSpec typically 2C (44 decimal). The ID must be
specified in Hex format.Click Save to save the changes.

Fig. 48. Channel Info - Domain ID and Domain Length

fields.

4. Click the Devices tab and go to Device List screen.

5. Click Discover. A dialog box appears. Select Channel

as Channel 1 and click Discover. A progress bar
appears indicating the discovery progress.

6. After the discovery is complete, all the discovered
devices are listed on the left side of the table. Review
the subnet/node ids of discovered devices to ensure
that there are no conflicts. WebVision will detect the
clash and on confirmation from the user, it would
change the subnet/node id of the device.

Fig. 47. Advanced Features dialog box.

3. Set the Domain index for non-zero length domain to
0 (LNS based systems). Click OK to save the

changes.

4. Modify the original LonSpec project so that it does not
contain unsupported devices. The following are
frequently used:
a. XL15A
b. XL15B
c. Command Display 1 and 2
d. T7300
e. RapidLink/SLTA/PCLTA used by LonSpec, LonSta-

tion and XL15A.
f. RF Gateway
g. CX-VFD

It is highly recommended not to have these devices
physically connected to the Lon Network as it could
result in partial upload of binding information into WebVi­sion, or worse interfere with WebVision functionality.

5. Disconnect WebVision from the network and re­commission all the devices using LonSpec.

NOTE: Changing subnet/node id will break any bindings

going in and out of that device. It is suggested that
the user find the clash manually and rectify them
through LonSpec.

7. Select all the devices by clicking on each device (or
click the SelectAll box) and then click Add to add them
to WebVision database.

NOTE: The user should click on the device to select the

device in the discovered list to do further operation
on them. Although mouse scrolling across the
discovered devices records appear as selection,
they are actually not selected

8. Enter a name for each device that should appear in then
UI and click Done to complete the discovery process.

9. Select all the devices and click Upload to upload the
device configuration onto WebVision. A progress bar
appears indicating the progress of the Upload
operation. Once the upload is complete, the Synced On
option is enabled for each device.

10. Ensure that all the devices are in Auto mode in the
Mode Column. If any device is in Manual or any other
mode, select that device and click Set Mode to Auto.

11. Click the Device Bindings sub-tab next to Device List

subtab.

95-7769—01 32

WEBVISION™

12. Click Upload to upload the LON binding information
onto WebVision. A progress bar appears indicating the
progress of the Upload operation.

NOTES

1. Ensure all the devices are in Auto mode. If you

see any device in Manual or any other mode,
select that device and click Set Mode to Auto to
change the mode.

2. Click Download in Devices > Device List or

Devices > Device Bindings to initiate the
process of writing configuration data that is
present in WebVision to devices. This operation
should be performed only if it is absolutely
necessary. If there is no requirement to change
the configuration in the devices this operation
must not be performed.

3. The migration procedure has been tested with

LonSpec version 05.01.00.00 and later. It is
recommended that users use at least this version
for migration.

4. After the auto-resolution of Node ID conflict, if the

configuration upload fails (especially for XL15C),
user should wait a minute and retry the operation.

5. WebVision does not support access through

PPPoE connection. PPPoE is the data link layer
protocol used for broadband internet connections.
If the user is using PPPoE, the user is advised to
purchase a WiFi router or equivalent that supports
PPPoE and connect WebVision to the Ethernet
side of the router. Follow the User Guide of the
router to have the desired setup

6. It is recommended that all the device

configurations and bindings are checked field by
field to ensure that the migration was successful
as expected. If any information is found missing,
the user can retry upload operation of
configuration/bindings as applicable. If that does

not solve the problem, user should manually fill in
the missing information. Any attempts to do
download without performing this operation may
break the control system in the site.

7. Points can be overridden through any means in
WebVision for a period of time. However, if
WebVision is powered off during that period and
re-started, WebVision will not restore the point i.e.
will not cancel the override even if the specified
override time has elapsed. In this case, a stale
value will be observed in WebVision. To cancel
the original override operation, the user should
override the point again for a minute and that
would restore the default value.

8. If XL15Cs use Math Functions that are type
Network Special, the configuration will get
uploaded properly into WebVision. However the
WebVision interface does not show Math
Functions of type Network Special in the user
interface.

Configuring Chilled Ceiling Controllers (CHC)

Description

The W7763C, D and E Controllers are Chilled Ceiling
Controllers in the Excel 10 product line. They cover a wide
range of control applications including radiators, induction
units, and fan coil units with manual fan switching, chilled
ceiling and chilled beam and are suitable for either wall
mounting or unit mounting. The controllers can operate as
stand-alone units or networked using the standard Echelon

ONWORKS bus. Interfaces are provided for a wide range of

L
actuator types. Heating systems can be water or electric, and
cooling systems can be chilled water supply or compressors.
Extensive timing and interlock features make the W7763
especially suitable for systems using electric heat and
compressors.

Navigating to CHC Pages

Go to the Devices tab. Expand the list of devices on the left
pane (listed under WebVision). Select a device to view its
properties.

The W7763C, D and E are LonMark-compliant Chilled Ceiling
Controllers in the Excel 10 family product line. These
controllers provide room temperature control using different
heating and cooling sequences. The controller is provided
with default configuration settings from the factory and is fully
operable on installation. Using standard Echelon configuration
tools, the controller can be configured with job-specific
settings. The TR21 and TR23 wall modules interface with the
Chilled Ceiling Controllers and provide the following options:
setpoint adjustment, an occupancy bypass button and LED,

Sequences

Heat and cool sequences can be selected to be active or not
active, giving a total of four different sequence options:

• Heat only

• Cool only

• Heat/cool changeover

• Heat and cool sequence

The controller automatically disables heat and cool control
until the window is closed again. Frost protection remains
active.

Modes of Operation

The controller has the following modes of operation:

Occupied mode This is the normal operating condition for a
room or zone when it is occupied. The controller can be
switched into this mode by a network command, by the room
occupancy sensor, or by a bypass button on the wall module.

Standby mode The standby mode saves energy by reducing
heating or cooling demand during periods where the room is
temporarily unoccupied.

Unoccupied mode This mode is used for longer unoccupied
periods, such as at night or during weekends and holidays.

Window open If the controller is configured for window open
detection, the controller automatically disables heat and cool
control until the window is closed again. Frost protection
remains active.

Frost protection If the temperature drops below 46 °F
(8 °C), the controller enables the heating circuit as frost
protection.

95-7769—01 34

WEBVISION™

Fan fail When configured with an air flow detector, the
controller protects equipment by disabling the system when
the fan fails (for fan coil units with manual fan speed control).

Changeover The controller operates two-pipe units
configured with a changeover input.

Dewpoint When configured with a chilled water temperature
sensor, the controller will close the cool valve when the chilled
water temperature falls below the dew point. The dew point
may be a fixed value or calculated based upon input from a
humidity sensor.

Condensation When configured with a condensation switch,
the controller will close the cool valve when condensation is
detected.

No Condensation Protection

Disable the dew-point temperature calculation and protection. The cold water temperature and the humidity are
not needed by the controller; the chilled ceiling protection can still be performed by the condensation switch.

System

Define the type of equipment that is being controlled in terms of the number of pipes used on the unit.

Two Pipe

A unit that has only two pipes. Selecting this system type limits the controller to control only one valve output and
operate in a changeover mode. When operating in the changeover mode, the controller uses only the one valve
for controlling both heating and cooling. Use this configuration only when changeover operation is required.

Four Pipe

A unit that has four pipes connected, providing both heating and cooling at the same time. The controller uses
one output to control heating only and one output to control cooling only, as configured in the Outputs page.

Control Outputs

Table 9. CHC Inputs - Field Definitions.

Name Field and Definition

Controller / Wall Module

Configures the functionality of the connected wall module. Be careful that the features configured here are the same as the features
available on the wall module device to be connected.

Space Temp Sensor

Specify whether or not the controller is to be used with a space temperature sensor connected to its input. Normally, a space
temperature sensor is used, but in cases where the space temperature is supplied from another device via the network, the local
space temperature sensor input is not used.

Ye s

The local space temperature sensor input is used. Ensure that a space temperature sensor is actually connected otherwise the
controller measures incorrect values.

No

The local space temperature sensor is not used. This option must be selected when a sensor is not connected.

LED/LCD Display

This configuration defines whether a Wall Module with LED or a Wall Module with LCD Display is connected.

1. Click the Inputs button on the left pane to open the
Input Configuration page.

2. Enter information into available fields.

3. Click Commit to save the settings or Reset to revert to

Controller / Wall Module (continued)

LED Occupancy

The LED shows the effective Occupancy mode. On indicates effective Occupied or Bypass, 1 Flash per Second indicates effective
Standby, Off indicates effective Unoccupied. 4 Flashes indicates the Controller answers of the Network Management Command
Wink.

LCD Display

This mode is used only for a Wall Module with LCD Display. The Display has following Symbols to show the Occupancy Modes: Sun
indicates effective Occupied or Bypass, Half Sun indicates effective Standby, Moon indicates effective Unoccupied. No Symbol and
OFF in 7-Segment indicates the Controller is Off. In the Off mode, a Snow Flag indicates whether Frost Protection is configured.
Blinking Symbols are used to show the Override: Blinking Sun indicates Override Occupied or Bypass, blinking Half Sun indicates
Override Standby, Blinking Moon indicates override unoccupied. The Controller answers with the Network Management Command
Wink with blinking Sun and Moon.

Override Button

Define how the override button on the connected wall module is to be used.

None

The wall module button is not used for bypass function.

ByPass Only

The Bypass button, when pressed, has two different functions depending on the length of time the button is held down:
Two seconds puts the controller in Bypass.
Five seconds puts the controller in Unoccupied.

Bypass

The Bypass button, when pressed, has the following function:
In two seconds the controller is in Bypass mode.

Setpoint Knob

The setpoint knob is available in different types of scale, and with different setpoint meanings, based on the country of usage. The
temperature engineering unit used (°C or °F) is the setting made in WebVision when creating the new project. That setting is used
for the total project. Note that the setpoint knob only affects the Occupied and Standby Setpoints. The Unoccupied setpoint is not
affected by the setpoint knob. Note that Version C and D Chilled Ceiling controllers have an on-board setpoint. They cannot be used
with an external TR21 or TR23 setpoint device.

The range of setpoint knob value lies between -9tdf to +9tdf.

No Knob

The setpoint knob is ignored. Note that this must be chosen if there is no setpoint knob connected to the controller. This selection
prevents the controller from reacting to incorrect setpoint values.

Relative

The setpoint knob is a relative knob, showing only a setpoint shift as (+) and (-) changes to the configured setpoint.

Absolute Middle

The setpoint knob is an absolute knob, showing the setpoint in absolute degrees. It is used as the space temperature setpoint
midway between the heating and cooling zero energy band.

Setpoint Limits

These two fields specify the allowed range of adjustment available from the wall module setpoint knob. This range is used by the
building manager for energy management purposes, to balance allowed comfort conditions with energy usage.

(SETPOINT KNOB = RELATIVE)

When the setpoint knob has been chosen as relative, the setpoint limits define the range of adjustment of the setpoint knob from the
zero point, in (DDC) for °C installations and (DDF) for °F installations.

(SETPOINT KNOB = ABSOLUTE MIDDLE)

When the setpoint knob has been chosen as absolute, the setpoint limits are limits on the absolute range of the setpoint knob in
(Deg.C) for °C installations and (Deg.F) for °F installations.

Analog Input 1 and Analog Input 2

a

Window Closed

Indicates if a window is closed. Close window disables the controller operation. If the contact is closed, the window is closed.

Window Open

Indicates if a window is opened. An open window enables the controller operation. If the contact is closed, the window is closed.

Occupied Sensor

Indicates if the room is occupied. If the contact is closed, the space is occupied.

Unoccupied Sensor

Indicates if the room is unoccupied. If it is unoccupied, the controller switches from the occupied operating setpoints to the standby
operating setpoints.

ChangeOver Cool

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch. When the
contact closes, this input indicates that the system can operate in cooling mode. When the contact opens, this input indicates that
the system can operate in heating mode.

ChangeOver Heat

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch. When the
contact closes, the input indicates that the system can operate in heating mode. When the contact opens, the input indicates that
the system can operate in cooling mode.

Condensation

Indicates if there is condensation in the ceiling. When condensation is detected, the controller closes the cooling output. The cooling
output is controlled again after 5 minutes if condensation is not detected anymore. When the contact closes, there is condensation.

No Condensation

Indicates if there is no condensation in the ceiling. As long as there is no condensation, the contact is closed. If the contact opens,
the controller closes the cooling output. The cooling output is controlled again after 5 minutes if condensation is no longer detected.
When the contact closes, there is no condensation.

Movement

This selection is used for movement detector configuration where a closed contact indicates movement. Movement detector is the
same as occupancy sensor, but with an additional Hold Time of 15 minutes. This adds a delay to the occupancy signal such that the
space is considered occupied until 15 minutes has elapsed since the last movement is detected.

Cold Water

The cold water temperature sensor input is used. Ensure that a cold water temperature sensor is actually connected otherwise the
controller measures incorrect values.

Not Used

The cold water temperature sensor is not used. This option must be selected when a sensor is not connected and is shared via the

Defines the operating characteristics of the two valve actuator outputs.
Output 1 and Output 2

Define operation of output 1 and output 2, as configured in the Outputs page. The settings for both Outputs have
the same meaning as described in the following text.

Valve Direction

Define the operating direction of the valves for actuator types Floating, PWM, and Thermal.

Direct

To open, the valve is modulated from 0% to 100%.

Reverse

To open, the valve is modulated from 100% to 0%.

Min Stage Off Time

Define the minimum off-time for control outputs configured for operation as staged outputs. This setting is
particularly useful for heat exchanger operation or compressor units. Each stage of the controlled output
stays off for the minimum period of time before the controller turns it on again. The selectable range is 0 to
600 seconds.

Valve Runtime

This configuration parameter has three different functions depending on the control output type selected in
Control Outputs.

(CONTROL OUTPUT TYPE = FLOATING)

The value is the actuator run-time in the range 20 to 600 seconds.

(CONTROL OUTPUT TYPE = PWM)

The value is the cycle period of the PWM output in the range 20 to 600 seconds.

(CONTROL OUTPUT TYPE = ONE, TWO OR THREE STAGE)

The value is the minimum on-time for each of the stages, for controlling compressor units

PWM Options

Configures the full range of the PWM outputs. For many PWM-controlled devices, an output of 0% or 100% is not
allowed since a PWM output shows no switching at these percentages. Therefore, most PWM devices have a
minimum duty cycle and a maximum duty cycle between which they operate from zero to full scale. The fields here
configure the full range settings. You can swap the Zero and Full range values to achieve reverse operation for a
PWM output.

Name Setting and Definition

PID

Cooling/Heating

Allows the algorithm control parameters to be configured.

Proportional band

This value is the temperature deviation between setpoint and space temperature, which causes the control
output to modulate from 0% to 100% of full range. The variable can be set in the range 2 to 100DDC (3.6 to
180DDF), 1.3 to 100DDC (2.3DDF to 180DDF) for Proportional Control only.

Reset Time

This value is the integral reset time in the range 0 to 3200 sec. Setting the Integral constant to zero disables
integral operation.

Derivative Time

This value is the derivative constant in the range 0 to 3200 sec. Setting the derivative constant to zero disables
derivative operation.

Thermal Switching Band/PID Boost

Cooling/Heating
Boost Temp

Allows a boost band to be set for normal PID operation and when using thermal actuators. The variables indicate
a setpoint-space temperature deviation outside which the outputs are switched to full operation to act as a boost
function when space temperature deviates significantly from the desired setpoint. This band also serves as a
threshold for two-point switching of thermal actuators. The threshold can be set in the range 0 to 10DDC (7.2 to
180DDF). If the threshold is set to 0DDC, the boost function is disabled.

CVAHU PID

Purpose

Adjust PID (Proportional Integral Derivative) control
parameters for the CVAHU.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Equipment Damage Possible.

Can cause short cycling of compressors or wide
swings in space temperature and excessive
overdriving of modulating outputs.

If large or frequent change to PID control parameters
is made, it is possible to cause equipment problems
such as short cycling compressors (if the stage
minimum run times were disabled). Other problems
that can occur include wide swings in space
temperature and excessive overdriving of modulating
outputs.

The default values provide proper control for most
applications. If the PID parameters require adjustment away
from these values, use caution to ensure that equipment
problems do not arise. If any change to PID control
parameters is made, the adjustments should be gradual. After
each change, allow the system to stabilize so the effects are
accurately observed. Make further refinements as needed
until the system is operating as desired.

If the default values are changed and you want to reset them,
add a second CVAHU Controller to the subnet, record then re­enter the default PID values to the first CVAHU.

Integral Time

Determines what impact the error-over-time has on the output
signal. Error-over-time has two components that make up its
value: the amount of time the error exists and the size of the
error. The higher the integral time, the slower the control
response. In other words, a decrease in Integral Time causes
a more rapid response in the output signal.

Equipment Damage Possible.

Setting Control Band too low may cause large over or
undershooting of setpoint.

The smaller the Control Band, the more responsive the control
output. Be careful not to set the Control Band (heating,
cooling, or econ) too low. This can happen if the space or

Derivative Time or Gain

Determines what impact the error rate has on the output
signal. The error rate is how fast the error value is changing. It
can also be the direction space temperature is going, either
towards or away from the setpoint and its speed - quickly or
slowly. A decrease in Derivative Time causes a given error
rate to have a larger effect on the output signal.

• Occupied mode
This is the normal operating condition for a room or zone
when it is occupied. The controller can be switched into
this mode by a network command, by the room occupancy
sensor, or by a bypass button on the wall module. In the
occupied mode the fan is controlled by the setting of the
fan speed switch on the wall module or by the control algo­rithm when the switch is set to auto. The fan can be
configured to remain on or turn off during the zero energy
band.

• Standby mode
The standby mode saves energy by reducing heating or
cooling demand during periods where the room is tempo­rarily unoccupied. In this mode the fan is switched off
during the zero energy band.

• Unoccupied mode
This mode is used for longer unoccupied periods, such as
at night or during weekends and holidays.

• Window open
The controller is configured for window open detection, the
controller automatically disables heat and cool control until
the window is closed again. Frost protection remains
active.

95-7769—01 54

• Frost protection
If the temperature drops below 46 °F (8 °C), the controller
enables the heating circuit as frost protection.

WEBVISION™

• Fan fail
When configured with an air flow detector, the controller
protects equipment by disabling the system when the fan
fails

• Changeover
The controller operates two-pipe FCUs configured with a
changeover input.

Display

Override
Button

Specify whether or not the controller is to be used with a space temperature sensor connected to its input. A
space temperature sensor is typically used, but in cases where the space temperature is supplied from
another device via the network, the local space temperature sensor input is not used.

YES

The local space temperature sensor input is used. Ensure that a space temperature sensor is actually
connected otherwise the controller measures incorrect values.

NO

The local space temperature sensor is not used. This option must be selected when a sensor is not
connected.

This configuration defines whether a Wall Module with LED or a Wall Module with LCD Display is connected.
For the LED there is shown either the Override Status or the Effective Occupancy Status. The LCD Display
show both the Effective and the Override Status, and an additional Off Condition.
The Override Status results from the Scheduler, the Network Override, the Override Button and the
Occupancy Sensor. The Off Condition results from the Fanspeed Switch, the Window Contact and the
Medium from nviApplicMode.

LED Override

The LED shows the Override from the Override Button or from the Network. On indicates Override Bypass, 1
Flash per Second indicates Override Unoccupied, 2 Flashes per Second indicates Override Standby or
Occupied. 4 Flashes indicates the Controller answers of the Network Management Command Wink.

LED Occupancy

The LED shows the effective Occupancy Mode. On indicates effective Occupied or Bypass, 1 Flash per
Second indicates effective Standby, Off indicates effective Unoccupied. 4 Flashes indicates the Controller
answers of the Network Management Command Wink.

LCD Display

This mode is used only for a Wall Module with LCD Display. The Display has following Symbols to show the
Occupancy Modes: Sun indicates effective Occupied or Bypass, Half Sun indicates effective Standby, Moon
indicates effective Unoccupied. No Symbol and OFF in 7-Segment indicates the Controller is Off. In the Off
Mode, a Snow Flag indicates whether Frost Protection is configured. Blinking Symbols are used to show the
Override: Blinking Sun indicates Override Occupied or Bypass, blinking Half Sun indicates Override Standby,
Blinking Moon indicates override unoccupied. The Controller answers with the Network Management
Command Wink with blinking Sun and Moon.

Setpoint
Knob

The setpoint knob is available in different types of scales, and with different setpoint meanings, based on the
country of usage. The temperature engineering unit used (°C or °F) is the setting made in WebVision when
creating the new project. This setting is used for the total project.

NOTE: The setpoint knob only affects the Occupied and Standby Setpoints. The Unoccupied setpoint is not

affected by the setpoint knob.

No Knob

The setpoint knob is ignored. Note that this must be chosen if there is no setpoint knob connected to the
controller. Selecting “NO” prevents the controller from reacting to incorrect setpoint values.

Relative

The setpoint knob is a relative knob, showing only a setpoint shift as (+) and (-) changes to the configured
setpoint.

Absolute Middle

The setpoint knob is an absolute knob, showing the setpoint in absolute degrees. It is used as the space
temperature setpoint midway between the heating and cooling zero energy band.

Setpoint
Limits

These two fields specify the allowed range of adjustment available from the wall module setpoint knob. It is
used by the building manager for energy management purposes to balance allowed comfort conditions with
energy usage.

(SETPOINT KNOB = RELATIVE)

When the setpoint knob as been chosen as relative, the setpoint limits define the range of adjustment of the
setpoint knob from the zero point, in (DDC) for °C installations and (DDF) for °F installations.

(SETPOINT KNOB = ABSOLUTE MIDDLE)

When the setpoint knob has been chosen as absolute, the setpoint limits are limits on the absolute range of
the setpoint knob in (Deg.C) for °C installations and (Deg.F) for °F installations.

Digital Input
Points

Specifies usage of the digital input of the controller.

Digital Input 1

Window Closed
Indicates if a window is opened. An open window disables the controller operation. If the contact is closed,
the window is closed.

Window Open

Indicates if a window is opened. An open window disables the controller operation. If the contact is closed,
the window is open.

Occupied Sensor

Indicates if the room is occupied. While unoccupied, the controller switches from the occupied operating
setpoints to the standby operating setpoints. If the contact is closed, the space is occupied.

Unoccupied Sensor

Indicates if the room is unoccupied. While unoccupied, the controller switches from the occupied operating
setpoints to the standby operating setpoints. If the contact is closed, the space is unoccupied.

Air Flow

For monitoring correct fan operation using an air flow switch. When the fan is commanded on, the controller
monitors this input for the fan run-up time. If the fan does not run within 30 seconds, the input indicates that
the fan has failed. Similarly, the input indicates if the fan fails during normal operation. If the contact is closed,
the fan runs.

No Air Flow

For monitoring correct fan operation using an air flow switch. When the fan is commanded on, the controller
monitors this input for the fan run-up time. If the fan does not run within 30 seconds, the input indicates that
the fan has failed. Similarly, the input indicates if the fan fails during normal operation. If the contact is closed,
the fan is not running.

ChangeOver Cool

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat
switch. When the contact closes, this input indicates that the system can operate in cooling mode. When the
contact opens, this input indicates that the system can operate in heating mode.

Changeover Heat

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat

Movement

This selection is used for movement detector configuration where a closed contact indicates movement.
Movement detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This
adds a delay to the occupancy signal such that the space is considered occupied until 15 minutes has
elapsed since the last movement is detected.

No Movement

This selection is used for movement detector configuration where a closed contact indicates no movement.
Movement detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This
adds a delay to the occupancy signal such that the space is considered occupied until 15 minutes has
elapsed since the last movement is detected.

Not Used

This setting indicates that the digital input is not used. Use this setting if nothing is connected to the controller
to ensure that spurious signals do not cause the controller to operate incorrectly. The status of this digital
input is reported to the network for use as a free digital input if required. It has no effect on the control
algorithm.

Output 1 / Output 2

Define operation of output 1 and output 2 as configured in the Outputs page. The fields have the same meanings for
both outputs.

Fan Interlock

Normally used to protect electric heating coils controlled by Output 1 or Output 2. Without this protection, heating coils
can overheat. This option can also prevent ice-up or condensation build-up on cooling or compressor coils.

Yes

The fan always turns on for the run-up time before turning on the control output, to ensure air is flowing over the electric
heating coil before turning on the electric coil. The fan continues to run after the electric coil is turned off, for the post-run
time, to ensure the electric coil is cooled down before the fan turns off.
Similarly, for cooling coil condensation protection, the fan re-run and post-run times are observed.
Additionally, if the digital input is configured for fan fail detection, and the fan does not operate within the defined run-up
time, then the control output is not turned on. This action also occurs if the fan fails during normal operation.

No

There is no interlock between fan operation and the control outputs.

Valve Direction

Define the operating direction of the valves for actuator types Floating, PWM, and Thermal.

Min Stage Off Time

Define the minimum off-time for control outputs configured for operation as staged outputs. This setting is particularly
useful for heat exchanger operation or compressor units. Each stage of the controlled output stays off for the minimum
period of time before the controller turns it on again. The selectable range is 0 to 600 seconds.

Valve Runtime

This configuration parameter has three different functions depending on the control output type selected in Control
Outputs:

(CONTROL OUTPUT TYPE = FLOATING) The value is the actuator run-time in the range 20 to 600 seconds.
(CONTROL OUTPUT TYPE = PWM) The value is the cycle period of the PWM output in the range 20 to 600
seconds.
(CONTROL OUTPUT TYPE = ONE, TWO OR THREE STAGE) The value is the minimum on-time for each of the
stages, for controlling compressor units.

Reheat
Options

PWM
Options

Defines the control output level at which the electric reheat relay (relay 4) switches.

Switch Level

Define the control output level at which the electric reheat output switches on. Range 0% to 100%.
Use a setting of 5% where electric heating has priority over a water heating valve, for example, as the first heating
sequence. Or use for electric heating control only.
Use higher settings, for example, 90%, where water heating has priority over electric heating. Or when electric heating
is required during summer/winter changeover periods.

Hysteresis

Define the control output level (Switch level - Hysteresis) at which the Reheat control output switches off.
Allows the full range of the PWM outputs to be configured. Many PWM-controlled devices cannot provide an output of

0% or 100% because a PWM output shows no switching at these percentages. Therefore, most PWM devices have a
minimum duty cycle and a maximum duty cycle between which they operate from zero to full scale. The fields here allow
you to configure the full range of settings. It is possible to swap the Zero and Full range values to achieve reverse

Description

The W7762A and B Controllers are Hydronic Controllers in
the Excel 10 product line. They cover a wide range of control
applications including radiators, induction units, and fan coil
units with manual fan switching, and are suitable for either

Description

The W7762A and B are LonMark compliant Hydronic
Controllers in the Excel 10 family product line. These
controllers provide room temperature control using different
heating and cooling sequences. The controller is provided
with default configuration settings from the factory and is fully
operable on installation. Using standard Echelon configuration
tools, the controller can be configured with job specific
settings. TR21 and TR23 wall modules interface with the
Hydronic Controllers and provide the following options:
setpoint adjustment, an occupancy bypass button and LED,
and a LON network access jack. All wall include a space
temperature sensor, however a remote C7068A return air
sensor can also be used.

WEBVISION™

Heat and cool sequences can be selected to be active or not
active, giving a total of four different sequence options:

• Heat only

• Cool only

• Heat/cool changeover

• Heat and cool sequence

Modes Of Operation

The controller has the following modes of operation.

Occupied mode

This is the normal operating condition for a room or zone
when it is occupied. The controller can be switched into this
mode by a network command, by the room occupancy sensor,
or by a bypass button on the wall module.

Standby mode

The standby mode saves energy by reducing heating or
cooling demand during periods where the room is temporarily
unoccupied.

Unoccupied mode

This mode is used for longer unoccupied periods, such as at
night or during weekends and holidays.

Window open

If the controller is configured for window open detection, the
controller automatically disables heat and cool control until the
window is closed again. Frost protection remains active.

Frost protection

If the temperature drops below 46 ºF (8 ºC), the controller
enables the heating circuit as frost protection.

Fan fail

When configured with an air flow detector, the controller
protects equipment by disabling the system when the fan fails
(for fan coil units with manual fan speed control).

Changeover

The controller operates two-pipe units configured with a
changeover input.

System

Define the type of equipment (number of pipes) being controlled.

TWO_PIPE

Unit has only two pipes. Selecting this system type limits the controller to control only one valve output and operate in
a changeover mode. When operating in changeover mode, the controller uses only the one valve for controlling both
heating and cooling. Use this configuration only when changeover operation is required.

FOUR_PIPE

Unit has four pipes connected, providing both heating and cooling at the same time. The controller uses one output to
control heating only and one output to control cooling only (as specified in Control Outputs).

Configures the two control outputs for the different type of actuators and control sequences required for the application.

Output 1- Mode

Output triac pair connected to terminals 13/14/15 of the controller.
Select the control sequence option for output 1. For four-pipe applications, always allocate this output to the heat
option to minimize field wiring errors. For two-pipe applications, you can select only the changeover option.

HEATING

The output is modulated open when heat energy is needed in the space.

COOLING

The output is modulated open when cool energy is needed in the space.

CHANGEOVER

The output is modulated open when heat or cool energy is needed in the space.

OUTP_NOT_USED

the features available on the wall module device to be connected.

Space Temp Sensor

Define whether or not the controller is to be used with a space temperature sensor connected to its input. Typically, a
space temperature sensor is used, but in cases where the space temperature is supplied from another device via the
network, the local space temperature sensor input is not used.

YES

The local space temperature sensor input is used. Ensure that a space temperature sensor is actually connected,
otherwise the controller measures incorrect values.

NO

The local space temperature sensor is not used. This option must be selected when a sensor is not connected.

LED/LCD Display

This configuration defines whether a Wall Module with LED or a Wall Module with LCD Display is connected.
For the LED there is shown either the Override Status or the Effective Occupancy Status. The LCD Display shows the
both – the Effective and the Override Status and an additional Off Condition.
The Override Status results from the Scheduler, the Network Override, the Override Button and the Occupancy Sensor.
The Off Condition results from the Fanspeed Switch, the Window Contact and the Medium from nviApplicMode.

LED_OVERRIDE

The LED shows the Override from the Override Button or from the Network. On means Override Bypass, 1 Flash per
Second means Override Unoccupied, 2 Flashes per Second means Override Standby or Occupied. 4 Flashes
means the Controller answers of the Network Management Command Wink.

LED_OCCUPANCY

The LED shows the effective Occupancy Mode. On means effective Occupied or Bypass, 1 Flash per Second means
effective Standby, Off means effective Unoccupied. 4 Flashes means the Controller answers of the Network
Management Command Wink.

LCD_DISPLAY

This Mode is used only for a Wall Module with LCD Display. The Display has following Symbols to show the
Occupancy Modes: Sun means effective Occupied or Bypass, Half Sun means effective Standby, Moon means
effective Unoccupied. No Symbol and OFF in 7-Segment means the Controller is Off. In the Off Mode, a Snow Flag
indicates whether Frost Protection is configured. Blinking Symbols are used to show the Override: Blinking Sun

Digital
Input
Points

Specifies usage of the controller's digital input. Digital Input 1.

DI_WINDOW_CLOSED

Indicates if a window is opened. An open window disables the controller operation. If the contact is closed, the
window is closed.

DI_WINDOW_OPEN

Indicates if a window is opened. An open window disables the controller operation. If the contact is closed, the
window is open.

DI_OCCUPIED_SENSOR

Indicates if the room is occupied. While unoccupied, the controller switches from the occupied operating setpoints to
the standby operating setpoints. If the contact is closed, the space is occupied.

DI_UNOCCUPIED_SENSOR

Indicates if the room is occupied. While unoccupied, the controller switches from the occupied operating setpoints to
the standby operating setpoints. If the contact is closed, the space is unoccupied.

DI_CHANGEOVER_COOL

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch.
When the contact closes, this input indicates that the system can operate in cooling mode. When the contact opens,
this input indicates that the system can operate in heating mode.

DI_CHANGEOVER_HEAT

This selection is for local heat/cool changeover operation for two-pipe units using a switch or local thermostat switch.
When the contact closes, the input indicates that the system can operate in heating mode. When the contact opens,
the input indicates that the system can operate in cooling mode.

DI_MOVEMENT

This selection is used for movement detector configuration where a closed contact indicates movement. Movement
detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This adds a delay to the
occupancy signal such that the space is considered occupied until 15 minutes has elapsed since the last movement
is detected.

DI_NO_MOVEMENT

This selection is used for movement detector configuration where a closed contact indicates no movement.
Movement detector is the same as occupancy sensor, but with an additional Hold Time of 15 minutes. This adds a
delay to the occupancy signal such that the space is considered occupied until 15 minutes has elapsed since the last
movement is detected.

DI_NOT_USED

This setting indicates that the digital input is not used. Use this setting if nothing is connected to the controller to
ensure that spurious signals do not cause the controller to operate incorrectly. The status of this digital input is
reported to the network for use as a free digital input if required. It has no effect on the control algorithm.

Options

Defines the operating characteristics of the two valve actuator outputs, Output 1 and Output 2 as configured in the
Outputs tab. The settings for both Outputs have the same meaning as described in the following text.

Valve D irectio n

Define the operating direction of the valves for actuator types Floating, PWM, and Thermal.

DIRECT

To open, the valve is modulated from 0% to 100%.

REVERSE

To open, the valve is modulated from 100% to 0%.

Min Stage Off Time

Define the minimum off-time for control outputs configured for operation as staged outputs. This setting is particularly
useful for heat exchanger operation or compressor units. Each stage of the controlled output stays off for the minimum
period of time before the controller turns it on again. The selectable range is 0 to 600 seconds.
Min St On or PWM Per or Valve Runtime
This configuration parameter has three different functions depending on the control output type selected in Control
Outputs:

(CONTROL OUTPUT TYPE = FLOATING)

The value is the actuator run-time in the range 20 to 600 seconds.

(CONTROL OUTPUT TYPE = PWM)

The value is the cycle period of the PWM output in the range 20 to 600 seconds.

(CONTROL OUTPUT TYPE = ONE, TWO OR THREE STAGE)

The value is the minimum on-time for each of the stages, for controlling compressor units.

Configures the full range of the PWM outputs. For many PWM-controlled devices, an output of 0% or 100% is not
allowed since a PWM output shows no switching at these percentages. Therefore, most PWM devices have a minimum
duty cycle and a maximum duty cycle between which they operate from zero to full scale. The fields here configure the
full range settings. You can swap the Zero and Full range values to achieve reverse operation for a PWM output.

RIO Deltas

Use Table 52 to configure the RIO Deltas.

Purpose

Delta is an adjustable threshold that allows the user to
determine, on a per-sensor basis, what change in value is
required before the sensor is updated. All Excel 10 controllers
have a guaranteed periodic update time of 55 seconds, which
requires that all sensors report any change every update
period. The delta for each sensor is used to reduce LonWorks
Bus traffic by reducing the amount of updates on a sensor that
are constantly or quickly changing. View or modify Deltas
(change thresholds) for sensors.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Procedure

1. Click the Deltas_pane button on the left pane to open

Purpose

Adjust PID (Proportional Integral Derivative) control
parameters for the Unit Ventilator Controller.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Equipment Damage Possible

Can cause short cycling of compressors or wide

swings in space temperature and excessive
overdriving of modulating outputs.

If a large or frequent change to the PID control

parameters is made, it is possible to cause
equipment problems such as short cycling
compressors (if the stage minimum run times were
disabled). Other problems that can occur include
wide swings in space temperature and excessive
overdriving of modulating outputs.

The default values provide proper control for most
applications. If the PID parameters require adjustment away
from these values, use caution to ensure that equipment
problems do not arise. If any change to the PID control
parameters is made, the adjustments should be gradual. After
each change, allow the system to stabilize so the effects are
accurately observed. Make further refinements as needed
until the system is operating as desired.

If the default values are changed and you want to reset them,
add a second Unit Ventilator Controller to the subnet, record
then re-enter the default PID values to the first Unit Ventilator.

Defines the control method the controller uses when the controller status is set to morning warm-up.

Valid selections for this field are:

• Fixed Flow – The controller maintains a fixed air flow setpoint or damper position during the warm-up
period.

• Modulating Flow with Reheat – The air flow setpoint is reset by the local space temperature during the
warm-up period. If controller is at maximum flow and additional warm-up is required local reheat is used.

• Modulating Flow without Reheat – The air flow setpoint is reset by local space temperature during the
warm-up period. No local reheat is used during the warm-up period.

• CZS Terminal Load

The check box enables Proportional reheat flow.

When checked, the temperature control loop modulates the damper (pressure-dependent mode) or reset air
flow setpoint (pressure-independent mode) when the controller is in the reheat mode from Minimum Flow
Setpoint to the Reheat Flow Setpoint.

If the check box is not checked, then when the controller is in the reheat mode, there is a step change from
Minimum Flow Setpoint to the Reheat Flow Setpoint.

Defines the time it takes the damper motor actuator to travel from the full close to full open position or visa
versa. This time should reflect the damper travel time and not the motor actuator speed. Example, if the
actuator motor speed is 90 seconds but the travel time of the damper from full close to full open is 45
seconds then the Dmpr Mtr Spd should be set to 45 seconds.

Defines the time it takes the reheat actuator to travel from the full close to the full open position or visa versa.
This time should reflect the reheat valve travel time and not the motor actuator speed. Example, if the reheat
actuator motor speed is 125 seconds but the travel time of the valve from full close to full open is 90 seconds
then the Reheat Mtr Spd should be set to 90 seconds.

Configuring the Vacon NX Frequency Converter (NXVFD)

VACON NX frequency converter (NXVFD) is an electronic
device for control of speed and torque of three-phase
alternating current (AC) motors. NXVFD converts the fixed
frequency and voltage of the main supply (mains) to a variable
frequency and voltage, which can then be regulated to provide
flexible motor operation and reduce energy consumption.
VACON NX frequency converters can be connected to the
LonWorks network using a field bus board.

The VACON NXOPTC4 option board is equipped with an
FTT-10A transceiver supporting the Free Topology
transformer coupled network, which allows the network wire to
be connected as bus, star, loop or combination of these. The
converter can then be controlled, monitored and programmed
from the Host system. The LonWorks board shall be installed
in slot E on the control board of the frequency converter. The
converter can then be controlled, monitored and programmed
from the LONWORKS network.

Configuring the XL15C Controller

The options for configuring the XL15C Controller are as
follows:

• Local Inputs

• SetPoints (Loop Logic)

• Math Functions

• Control Loops

• Logic Loops

• Start Stop Loops

• Outputs

Configuring XL15C Local Inputs

The XL15C controller has 8 Analog Inputs and 8 Digital
Inputs.

ANALOG INPUTS

Analog Inputs are used to monitor external conditions, such
as temperature, humidity or pressure. These inputs are
commonly used for monitoring and as inputs to Control Loops,
Start /Stop Loops, Math Functions & Logic Loops.

Each Analog Input may be configured as Analog or Digital.

Analog Inputs configured as Analog can receive Input from
various types of sensors. Analog Inputs configured as Digital
can only receive digital signals as inputs

DIGITAL INPUTS

Digital Inputs are used to monitor external events, such as
contact closures (10 mA, 5Vdc). The contact closures initiate
alarms, monitor equipment status, and read pulse meters.
These inputs are commonly used as inputs to Control Loops,
Start /Stop Loops, Math Functions & Logic Loops.

Each Digital Input can be configured as Maintained,
Momentary, Counter Slow, Counter Fast, Pulse Meter.

An external digital input source is connected to the digital
input.

Poll Points

The XL15C controller utilizes poll points as a means to
retrieve data from other network devices. Data retrieved by a
poll point is available for linking to XL15C objects such as
math functions, control loops, logic loops, and start/stop loops.

The XL15C polls each point every two seconds. If the
response is not received within ten seconds the poll is
changed to once every 30 seconds. When the response is
received the poll rate returns to once every 2 seconds.

The XL15C controller supports a maximum of 20 poll points.

Purpose

Specify the attributes for up to eight analog inputs and the
sensor types and attributes for up to eight digital inputs.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Purpose

General Purpose Math functions are used to perform
operations like minimum, average, square root etc. on up to 6
floating point analog values available within the controller.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Procedure

1. On the Configuration page click Math Functions. The
Math Function page appears on the right pane.

2. Select a required math function from Select Function.

3. Type a Function Name.

4. Select an operator from Select Operator.

Configuring XL15C Control Loops

The XL15C controller may be configured for up to 10 Control
Loops.

In the simplest form, a Control Loop reads a sensor (i.e. the
control sensor) and calculates an output to maintain the
sensed value at a user defined set-point. There are many
variations of this. For inputs, the user can configure control,
reset, recovery, occupancy, enable/disable, and TOD bypass
sensors. For outputs, the users may configure up to 4
modulating analog outputs, up to 4 stages for each analog
output and an auxiliary digital output for controlling a fan or
pump.

The control portion of the loop is an Enhanced PID (EPID)
algorithm. The user configures control algorithm type (PID or
Non-linear), bias (position of set point within the proportional
band (i.e. 0% or 50%), direct/reverse acting output, which
sensor and outputs to use, throttling range, integral time,
derivative time, start up ramp time, recovery, reset and
sequencer parameters, set points, minimum on, off and
bypass times, DLC shed bump and lead/lag.

Purpose

Define up to ten control loops that create outputs based on
algorithms.

Mode

Configuration can be performed with the wizard Off-line or
On-line.

Procedure

1. On the Configuration page click Control Loop. The
Control Loop page appears on the right pane.

2. Select a control loop from Select Loop.

3. Type a Loop Name.

4. Select Algorithm Type. This field defines the algorithm

type for the control loop. The default type is
“Unconfigured”. The user can select the type to be “Flex
PID” or “Flex Non-Linear”. Only if the algorithm type is
“Flex PID” or “Flex Non-Linear” will the other controls in
the Control Loop page get enabled. Select the
corresponding radio button to select an algorithm type.

5. Select a priority from Occupancy Override Priority.
The two options for occupancy override priority are:

•With Network wins (the default), nviManOcc has
priority. If nviManOcc is some other value than
OC_NUL, then the result is the value on
nviManOcc. When nviManOcc is OC_NUL, then
nviBypass has priority. If nviBypass is SW_OFF/
SW_NUL then the wall module override is
evaluated. Both nviManOcc and the wall module
override use the internal bypass timers. nviBypass
depends upon the other node’s timer to control the
duration of the bypass. The Excel 15C keeps the
loop bypass_timer running while nviBypass is
SW_ON. If nviBypass goes away before the timer
expires, then the loop remains in bypass for the
balance of the timer.

•With Last in Wins, the last bypass source is used to
determine the state. If multiple sources change the
state in the same second, they are evaluated in
order: nviManOcc, nviBypass, wall module override.
Each second the algorithm looks for an update to
either nviManOcc, a change of state to nviBypass,
or the wall module override being pushed. If any of
these occur, then appropriate action is taken. Else,
the bypass timer is checked for expiration and the
current state returned.

6. Select/Type information for the following.
a. Input & Setpoints

• Inputs: Used to configure the inputs required for
the Control Loop.

• Setpoints: Control Loop can host separate
setpoints apart from main 40 setpoints. These
are used to drive the occupancy state of the
control loop.

93 95-7769—01

WEBVISION™

• Setpoint Override: A configured setpoint
overrides the existing setpoint if the
corresponding Digital Input is TRUE. The Digital
Input1 maps to Setpoint1, Digital Input2 maps to
Setpoint2, vice versa.

b. Loop Configuration

• Reset: Control loops allow the setpoint (only in
occupied mode) to reset either in the direction of
increased energy savings or in the direction of
the increased comfort. The reset of a control loop
is dependent on the analog reset sensor input.
The Zero Reset Sensor Value is the minimum
value above which the reset action occurs. The
engineering unit is the reset sensor engineering
unit. The Max Reset Sensor Value is the
maximum value below which the reset action
occurs. The Max Reset Amount is the value
subtracted from the setpoint when the setpoint is
reset as per the reset sensor input.

• Recovery: This is used to calculate the ramp
rate at which it must reach the setpoint.

• Control Params: This is used to configure the
EPID loop.

• Auxiliary: The Aux D.O.is always intermittent for
unoccupied mode. The options available are
Continuous and Intermittent. The On Time is the
minimum ON time for the auxiliary digital output.
It ranges from 0 to 254 minutes with a resolution
of 1 minute. The Off Time is the minimum OFF
time for the auxiliary digital output. It ranges from
0 to 254 minutes with a resolution of 1 minute.

• SetPoint Alarms:
The Alarm Pre Delay represents the time
required for the main sensor input value to be
beyond the range set by the Alarm Delta Above
setpoint or Alarm Delta Below setpoint (before
the SET_POINT_LOOP_ALARM is set). The
range is 0 to 65460 seconds with a resolution of
1 second
The Alarm Post Delay represents the time
required for the main sensor input value to be
within the range set by the Alarm Delta Above
setpoint or Alarm Delta Below setpoint (before
the SET_POINT_LOOP_ALARM return to
Normal is set). The range is 0 to 65460 seconds
with a resolution of 1 second.
The Alarm Delta Above Setpoint value
establishes the Alarm high limit for the main
sensor input. If the main sensor input value
increases above the effective setpoint value plus
the Alarm Delta Above Setpoint Value and
remains above for Alarm pre-delay time period
then a SET_POINT_LOOP_ALARM is set.
The Alarm Delta Below Setpoint value
establishes the Alarm low limit for the main
sensor analog input. If the main sensor input
value decreases below the effective setpoint
value minus the Alarm Delta Below Setpoint
value and remains below for Alarm pre-delay
time period then a SET_POINT_LOOP_ALARM
is set.

c. Sequencer & Stager

• Sequencer: The sequencer configuration values
x1, x2, y1, and y2 determine the conversion from
the primary control loop (EPID) to the three
sequencer analog outputs. The sequencer takes
the primary (EPID) analog output value and splits

it to three separate analog outputs. Each of the
sequenced analog outputs ranges from 0 to
100%. The uses are controlling heating,
economizer and cooling, or converting the
primary EPID analog output into more stages.
The Sequencer 1 (Heat) Start field represents
start (x) percent of Sequencer
The Sequencer1 (Heat) End field represents
end (y) percent of Sequencer 1.
The Sequencer2 (Econ) Start field represents
start (x) percent of Sequencer 2.
The Sequencer2 (Econ) End field represents
end (y) percent of Sequencer 2.
The Sequencer3 (Cool) Start field represents
start (x) percent of Sequencer 3.
The Sequencer3 (Cool) End field represents
end (y) percent of Sequencer 3.

For example,
Sequencer 1 (Heat) Start: x = 0% y = 100%.
Sequencer 1 (Heat) End: x = 33% y = 0%.
Sequencer 2 (Econ) Start: x = 33% y = 0%.
Sequencer 2 (Econ) End: x = 66% y = 100%.
Sequencer 3(Cool) Start: x = 66% y = 0%.
Sequencer 3 (Cool) End: x = 100% y = 100%.

• Staging
The Stage1-4 are used to control equipment with
ON and OFF states. Up to 4 digital outputs can
be assigned to each of the 4 analog outputs (16
total). Typically, the user would either assign 4
digital outputs to the primary analog output or up
to 12 digital outputs to the three sequenced
analog outputs. It can be configured as local or
remote digital outputs. The pseudo point can also
be selected.
The Lead Lag selection is used to equally share
the run time of the equipment among the stages.
The XL15C keeps track of run time by counting
the ON time every minute.
The Minimum On Time is the minimum time for
each staged digital output to be ON at a
resolution of 1 minute. It ranges from 0 to 254
minutes.
The Minimum Off Time is the minimum time for
each staged digital output to be OFF at a
resolution of 1 minute. It ranges from 0 to 254
minutes.
The Integral stage On Time is the interstage ON
time for the staged digital outputs at a resolution
of 1 minute. It is the time a lower numbered stage
must be ON before the next stage can turn ON. It
ranges from 0 to 254 minutes.
The Integral stage Off Time is the interstage OFF
time for the staged digital outputs at a resolution
of 1 minute. It is the time when a higher
numbered stage must be OFF before the next
stage can turn ON. It ranges from 0 to 254
minutes.

Configuring XL15C Logic Loops

The XL15C controller has 32 Logic Loops. Each configured
Logic Loop generates outputs by applying logic functions on
different analog and digital inputs selected. These logic loop
outputs are commonly used as inputs to control loops, start/

Configuring the T7350 Thermostat Controller (T7350)

The T7350 is a full-featured Commercial programmable
thermostat. The primary opportunity for a Commercial
thermostat is in buildings with less than 55,000 square feet.
These buildings include restaurants, shopping malls, office
buildings and banks. Commercial thermostats are used on
single zone rooftop units, split systems, heat pumps or hot/
chilled systems.

The electronic thermostat consists of two pieces, the cover
assembly and a subbase. The subbase(s) include the
equipment control connections. The subbase is mounted on
the wall and the thermostat cover assembly is mounted on the
sub base. Different subbases will be used for different
applications including; up to Three Heat/Three Cool or Two
Heat/Four Cool, modulating outputs, and dehumidification
high limit control. Each subbase is compatible with the
common cover assembly.
