EXCEL 12 FCU + LIGHT + SUNBLIND

APPLICATION

The Excel 12 Fan Coil Unit (FCU) + Light + Sunblind
application encompasses the entire room, including one fan
coil unit, two lights, and one sunblind.

The application is delivered together with the plug-in and must
be downloaded into the unit's flash memory during start-up.
Regardless of the given Excel 12 model, the user has the
option of choosing from among the many different available
Excel 12 applications. The user can customize the application
using Honeywell's LNS™ plug-in with CARE or any LNS™
tool (e.g. LonMaker for Windows™). Customizations can be
saved / reloaded for easy configuration of multiple devices.

Application Overview

One Fan-Coil Unit:

 Two sequences configurable for HEAT, COOL, and

CHANGEOVER.

 Support of thermal actuators, floating actuators, PWM,

0...10 Vdc, and staged output via triac outputs or relay
outputs.

 3-stage fan via triac outputs or relay outputs.
 Binary inputs for condensation, occupancy sensor,

window contact, etc.

Two Lights:

 ON / OFF switching dependent on:

 Occupancy sensor.
 Three effective occupancy modes (occupied / standby

/ unoccupied). Effective occupancy is determined on
the basis of the occupancy sensor, the schedule, and
override input (if any).

 Light level (determined on the basis of data received

via the L
sensor).

 Manual switching (via hardwired switches or

L

 Dimming / constant light control for two lights with just one

sensor. Dimming / constant light control is performed via
analog outputs (this requires an HFD [High-Frequency
Device] for dimming with 1...10 Vdc input).

One Sunblind:

 Positioning dependent on:

 The effective occupancy mode (occupied / standby /

unoccupied) determined by occupancy sensor, the
schedule, and override input (if any).

 Light level (determined on the basis of data received

via the L

 Manual command.
 Building supervisor command.

 Safety position dependent on:

 Frost / rain from weather station or XL500, etc.
 Wind speed (determined on the basis of data received

via the L

 Open windows (determined on the basis of data

received via the L
hardwired sensor) inhibit moving of sunblind.

Occupancy Modes:

 Occupied mode: The Excel 12 operates according to the

"occupied" heating and cooling set-points.

 Bypass: After the bypass button of a hardwired wall

module has been pressed or when corresponding data is
received via the L

ONWORKS® network, the Excel 12

operates temporarily according to the "occupied" heating
and cooling set-points. When the bypass time has
elapsed, the controller reverts to the previous mode. The
bypass time can be configured via plug-in.

 Standby mode: The Excel 12 operates according to the

"standby" heating and cooling set-points.

 Unoccupied mode: The Excel 12 operates according to

the "unoccupied" heating and cooling set-points.

 Occupancy sensor: The occupancy sensor is used for

FCU, light, and sunblind control. Hardwired and
L

ONWORKS® occupancy sensors are supported. The

occupancy sensor determines the effective occupancy
mode during scheduled occupied periods. Depending
upon the actual occupancy sensor state, the effective
mode will be either "occupied" or "standby."

Wall Modules:

 L

ONWORKS® wall modules.

 Hardwired wall modules (e.g. T7460, T7560).
 Wireless wall modules (e.g. W7070+T7270 or RT7070).

Master / Slave Functionality:

Benefits of Integrated Room Control

The Excel 12's light management functionality provides you
with a number of significant advantages:

Considerable Reduction in Energy Consumption:

 25...75% savings on electrical energy consumption for

illumination.

 Decreased heat generated by electric lights or incoming

solar radiation (by closing sunblind), thus reducing cooling
energy requirements.

 Decreased electrical energy consumption due to constant

light control (see section "Constant Light Control" on page

7).

 Sunlight can be used to heat the room (sunblind up) if the

room is unoccupied and to avoid unnecessary cooling
demands (sunblind down), as needed.

Increased Convenience:

 Occupancy sensor switches the light ON/OFF

automatically.

 Constant light control always provides the correct lighting.
 The sunblind is lowered if the current outdoor light level

exceeds a configurable limit and is raised if the current
light outdoor level drops below the desired limit, or in case
of strong winds.

 Usage styles (e.g. presentation, working, etc.) can be

configured in conjunction with the Web Office Console.

 Wireless control via ZAPP (see ZAPP System

Engineering, EN0B-0286GE51).

Increased Flexibility:

 Flexible room usage if a L

ONWORKS® wall module or

ZAPP (wireless remote control) is used.

Reduced Engineering Effort / Expenses:

 Just one LONWORKS® node (instead of three) is required

to cover HVAC, Light, and Sunblind.
 reduced engineering and installation effort (e.g. wiring,

binding, commissioning, etc.)

 lower cost due to reduced number of LNS™ credits
 lower hardware total loop costs

Interoperability

See also section “Approvals, Certifications, and Standards”
on page 8.

Device Configuration

The controller is configured using Honeywell's LNS™ plug-in.
The plug-in can be started from CARE 4.0 or any LNS™ tool
(e.g. LonMaker for Windows™).

LONMARK® Objects Network Variables

The Excel 12 supports the following LONMARK® objects:

 1 node object (see Fig. 8)
 1 space comfort controller object (#8501 SCC – Fan Coil)

(see Fig. 6)

 2 lamp actuator objects (#3040) (see Fig. 9)
 1 occupancy sensor object (#1060) (see Fig. 7)
 1 sunblind / closed-loop actuator object (#4) (see Fig. 10).

LONWORKS® Network Interface

The Excel 12 communicates within the LONWORKS® network
at a rate of 78 kbs via an FTT-10A Free Topology
Transceiver, which provides transformer isolation; the bus
wiring is thus insensitive to polarity.

Devices so equipped can be wired in daisy chain, star, loop,
or any combination thereof as long as the max. wire length
requirements are met. The recommended configuration is a
daisy chain with two termination modules. This layout allows
for max. bus length and has the highest communication
reliability, particularly when adding on to an existing bus.
Refer also to http://www.echelon.com

Configuration and Binding

Configuration is performed using Honeywell's LNS™ plug-in,
which can be started from CARE 4.0 or any LNS™ tool (e.g.
LonMaker for Windows™). Likewise, binding is performed
using CARE 4.0 or any LNS™ tool.

LONWORKS® Service Button and LED

All models feature a LONWORKS® service button (accessible
from the outside on top of the module).

The service pin message is broadcast:
 whenever the L

ONWORKS® service button is pressed;

 after each reset due to power-up, software reset;

2

 if a hardwired push button for lighting or sunblind is

pushed for more than 10 seconds.

All models feature a L

ONWORKS® service LED for com-

missioning and troubleshooting. The service LED displays
numerous different behaviors indicating various module states
for use in troubleshooting.

See also Excel 12 Installation Instructions (EN1B-0201GE51)
for more-detailed information.

Priority of Received/Read Sunblind Input

Depending upon the last command received/read before the
wind speed exceeds the set limit, the sunblinds will either
return to the required position or remain in the UP position
(see Table 1). Fig. 11 presents the priorities of sunblind input
received/read by the Excel 12.

Long and Short Housings

Models powered with line power (W7704A, B, D1016, and
D1024) are equipped with a built-in transformer and feature a
long housing (W X L X H = 180 X 76 X 110 mm).

Models powered with 24 Vac (W7704C, D1008, E1005)
require an external 24 Vac power supply and feature a short
housing (W X L X H = 126 X 76 X 110 mm).

Binary Inputs

The unit is equipped with four dry-contact binary inputs. The
binary inputs are fast (i.e. the signal must be stable for at
least 25 ms).

Binary Outputs

The triac outputs or relay outputs can be configured for
different functions.

Relay Outputs

The unit is equipped with up to two change-over (C-O) relays
and up to three normally-open (N-O) relays.

Analog Outputs

The unit is equipped with up to two 0...11 Vdc analog outputs
(with the exception of the W7704E1005, which supports only
a single such analog output), each of which can drive a max.
of ±1.1 mA.

Example: Floating Drives

You can configure the two triac outputs or two relays to
connect a floating drive (no mixing of triac outputs and relays
allowed). Once the outputs have been configured using
Honeywell's LNS™ plug-in, floating actuators can be directly
connected to them.

Analog Inputs

The unit is equipped with up to 7 analog inputs, all of which
can be configured as slow binary inputs (in which case the
signal must be stable for at least 1.25 sec) for the detection of
a slow signals (e.g. from a window contact).

Hardware Limits

 In order to ensure a reliable contact, a min. current of

50 mA is required.

 The normally-open contacts are designed for a max.

continuous current of 16 A. The normally-closed contacts
are designed for a max. continuous current of 1 A.

 In order to reduce the build-up of heat in the housing, the

max. combined allowable current flowing through all relays
simultaneously is 24 A (continuous).

 The max. peak in-rush current (20 ms) at the normally-

open contact is 80 A.

Triac Outputs

The unit is equipped with up to six triac outputs.

Hardware Limits for Excel 12 with Line Power Supply

 Low signal: 0 V; high signal: 24 Vac
 Max. 250 mA continuous current in sum for all triac

outputs together

 550 mA for max. 10 sec.
 cos  > 0.5

Hardware Limits for Excel 12 with 24 Vac Power Supply

 Low signal: 0 V; high signal: 24 Vac
 Max. 500 mA continuous current in sum for all triac

outputs together

 800 mA for max. 10 sec.
 cos  > 0.5

NOTE: For controlling thermal actuators, we recommend

using the 24 Vac models, which provide more
current.

Constant Light Control

If, when configuring your Excel 12 application, you provide for
a light sensor (by selecting the "Daylight Sensing" checkbox
in the appropriate sub-screen of the plug-in), you must
specify, in lux, the desired minimum and maximum light levels
("Daylight: dark level" and "Daylight bright level, respectively).
The values you choose will then be used to switch the lights
ON and OFF.

NOTE: Do not select the “Auto Off Delay Timer” checkbox

insofar as this functionality is currently not supported.

NOTE: The light sensor employed for constant light control

must be suitable for artificial light, and should be
mounted more towards the corridor.

Constant light control helps save additional energy. Over their
lifecycle, fluorescent tubes normally lose about 15% of their
illumination. To compensate for this, rooms are therefore
usually dimensioned with 15% more illumination than actually
necessary. With constant light control, the light level can drop
as low as 85%, and the required brightness can still be
achieved. Further savings and comfort can be achieved if
there is a constant light level in the room and the light is
automatically dimmed when more outside light enters. The
Excel 12 supports window correction in order to reduce the
light output of the window light. Via the plug-in, this can be
selected and the offset also adjusted.

Example: The corridor light provides 400 lux and the window
light 320 lux. It is possible to override the constant light
control by manually dimming the light.

For constant light control, you must specify the set-point, the
darkness level, a correction for window lights (in general,
during the daytime, the window light has a lower light level
than the floor light), and also whether you want it to be
possible to switch on the light manually (e.g. in case of a
bright room).

The light intensities typically encountered in everyday life are
listed in Table 4, while Table 5 presents the recommended
light levels in various environments as set forth by DIN5035.

NOTE: One lux is equivalent to 0.0929 foot-candle.
