Installation & Operation Manual Control Air M/M+ Water to Water Applications | 5

2 Introduction

2.1 The Control Air M/M+ Interfaces

The Control Air M and M+ (M=Manager) is a Human-Machine Interface
(HMI) that interfaces with the BOSCH DDC Control Air 5600, enabling the
user to view and change property values, and/or control parameters, to
match a corresponding application whether it is a Water to Air or Water to
Water Heat Pump. It also provides a means of accessing and modifying the
controller’s schedule and real time clock in applications where a system
server or Building Automation System (BAS) is not available. The Control
Air M is designed for applications where there is one (1) WSHP. The
Control Air M+ is designed for applications where there is up to fi fty (50)
WSHP's (existing networks only).

The software is normally confi gured at the factory to match the unit
confi guration, however, there are cases where additional on-site changes
need to be made and this screen will allow the qualifi ed technical or
commissioning agent to incorporate such changes (without having to
download a diff erent software application) via the commissioning tool.
The interface is off ered in two forms: as a wall mount or unit mounted
Control Air M/M+module or in the form of an APP called the Equipment
Touch (OEM), which can be found in the Google Play Store (Android Only).

2.2 The Control Air M/M+ Module

The Control Air M/M+ module (Figure 1) is a touchscreen device with a

4.3" color LCD display that you connect to a Control Air 5600 to view or
change its property values, schedule units, view trends and alarms, and
more. The unit connects to the controller via the onboard serial port. The
module can be purchased by the following part numbers:

2.3 Virtual Control Air M/M+ (Equipment Touch (OEM) APP)

Virtual Control Air M/M+ (see Figure #2) provides the end-user an
interface to a controller by way of a Android Tablet and a purchased USB-L
cable (8733-927-403). The adapter; USB to micro USB (not provided by
BOSCH) may be needed if USB port is not available on Android device.
This adapter, not provided by Bosch, needs to be a female USB to male
micro USB. Once the cables are purchased, the corresponding driver will
need to be downloaded and installed before using the application. The
USB or micro USB end of the cable is connected to the Android device,
and the serial end is connected to the DDC controller. The Control Air M/
M+ cable driver, and instruction manual are all available for free download
at the Bosch Thermotechnology website.

WARNING: FIRE, INJURY HAZARD

 When working on equipment, always observe

precautions described in the literature, tags,
and labels attached to the unit. Follow all safety
codes. Wear safety glasses and work gloves. Use
a quenching cloth for brazing, and place a fire
extinguisher close to the work area.

Control Air M/M+ Water to Water Applications Installation & Operation Manual

9 The Control Air M and M+ Screens

9.1 Units Status Screen/Home Page

The Unit Status screen (Figure 14) is the home page for the Control Air
M, and shows the main menus/categories of the software the user can
interface with on the devices.

 Settings – For an installer, these settings allow for changes to

the device, as well as unit configuration at start-up.

 Service – For a service technician, this menu allows a user to

diagnose or troubleshoot the unit.

The screen provides valuable unit diagnostic data - entering and leaving
water temperatures, states of the compressors, Reversing valve, Pump.
It gives the user the ability to change the temperature units between
Fahrenheit and Celsius. The header of the screen is common to most
screens.

Figure 14

9.2 Settings Screen

The Settings page allows the user to access one of the following pages:

 Unit Settings
 Device Settings
 Alarm Settings
 *Pumps
 Temperature
 Schedule
 Setpoints
 *Lead/Lag

9.2.1 Unit Settings Screen

This screen can be accessed from the Settings menu. This menu allows
the commissioning agent to setup or modify operational parameters of the
unit.

Once all operational parameters are confi gured, these settings may be
saved and archived to fl ash memory by selecting the Save Settings check­box.

Figure 16

Occupancy Command

Under the Unit Settings screen, this parameter is used to select the
control source that will provide the occupancy command to the unit. The
options for this variable are the following:

 Digital Input
 Local Schedule
 BAS Command
 Manual Override

Throughout the setup process, by selecting diff erent boxes, this

is how you advance to the next setup screen if available, while
the back arrow is used to backtrack to previous screens.

Digital Input: The Digital Input option may be selected if the unit
occupancy is required to be controlled remotely via a switch (dry
contact) or other binary input. The connection (typically from a room
occupancy sensor) should be made in IN-1 of the controller. Choosing
this setting allows the unit to be placed in occupied mode once the
input is shorted to ground, and in unoccupied mode once the input is
opened.

*

If confi gured in Unit Settings.

Figure 15

Local Schedule: Schedule runs the unit on a local, modifi able
schedule, which cannot be accessed over a network. The occupancy
schedule for heating or cooling can be set according to the morning,
daytime, and night time settings for each day of the week. The option
will allow the unit to run on an 8:00 AM to 5:00 PM default schedule
everyday if the unit is to be started up during the construction phase of
the project. See the Schedule Screen for more information.

Installation & Operation Manual Control Air M/M+ Water to Water Applications | 15

BAS Command:

The unit factory default for the Occupancy Command
parameter is set to BAS Command. A qualifi ed technical agent may change
the parameter to be BAS Command, if diff erent from the default setting. This
option will enable the unit to be commanded from the BAS Server. The unit
is ready for BAS integration once this parameter is set up, and it can then
be commanded to occupied or unoccupied via the BAS by writing to the
Occupancy Status integration point (refer to Integration Points List document).

Manual Override: If the unit is intended to run all the time it can be set
to Manual Override, which will override the schedule and set the unit
into occupied mode indefi nitely, until the Manual Override option is
deselected.

Compressor Stages

This parameter allows the user to choose the number of compressors and stages
for the application. This parameter is typically set up from the factory to match the
unit confi guration and should only be changed by a qualifi ed technician.

Ensure the compressor confi guration is set accurately as this

selection will determine the code structure for reporting
compressor safety alarms from the Unit Protection Module
(UPM) to the controller. The fault codes for a 1 compressor 1
stage unit are diff erent from that for a 2 compressor 2 stage unit.

Mode Selection Method

This setting is similar to a thermostat mode select feature, which gives the user the
option of setting the unit mode. The options are: Heat, Cool, Off , Auto and Digital
input. When operating on Digital Input mode the unit will change from heat to cool
by using the state of the digital input (IN6) on controller as follows:

 Off = Heat
 On = Cool

This feature is typically used when the unit is not confi gured into a BAS network.
However, if there is a BAS network, it is recommended to operate the unit using
the integration points.

Figure 17

2 Compressor 2 Stages: This value is selected when unit has 2 compressors
and each compressor will operate as an independent stage.

1 Compressor 2 Stages: This value is selected when unit has 1 compressor
that has two independent stages. This is the default setting from the factory.

1 Compressor 1 Stage: This value is selected when unit has 1 compressor with
only 1 stage of operation.

Night Setback Enable:

This parameter allows users to enable or disable night setback feature.
Enabling Night setback will operate the unit under the following setpoints
when it enters the unoccupied state.

Control Air M/M+ Water to Water Applications Installation & Operation Manual

9.2.2 Device Settings Screen

Figure 18

The Device Settings menu allows the user to adjust or reset any settings
on the actual Control Air M/M+ module.

On this screen the BACnet® ID will be displayed. This value can be
changed, however, it is not recommend to change this parameter
arbitrarily as it may cause network problems.

Always consult with Network Administrator (Front End company) before
changing the controllers BACnet® ID as it may interfere with other devices
in the network.

Two main sub menus are available on this screen:

 Controller
 Touchscreen

9.2.2.1 Controller Screen

9.2.2.1.2 Communication

This screen lets you edit the information below for the controller.

Figure 21

Touch a fi eld to tap in new information.

— BACnet Device Instance – number
— Auto Generate Device ID – Enter No or Yes

You can edit the following fi elds that pertain to the controller's MS/
TP network:

— Max Masters - Set this to the highest MAC

address (up to 127) on the MS/TP network. If
you later add a device with a higher address, you
must change this field to that new address.

— Max Info Frames - Specifi es the maximum

number of information messages a controller
may transmit before it must pass the token to the
next controller. CAUTION Increasing this number
allows the controller to transmit more messages
while it has the token, but it also increases the
overall time it takes for the token to pass through
the network.

Figure 19

This screen provides access to the device Module Setup menu, that
provides the end-user the ability to set the time/date, update device
communication information, and access to the Time Master page.

9.2.2.1.1 Set Time and Date

Touch the time or date fi eld to edit it.

Figure 20

 For a router, set this value to a high number such as 200

 In non-router controllers, use the following formula to

calculate this value: [2 - (devices * (.002 + (80/baud))] /
[(600/baud) * devices] = Max Info Frames

For example, if the network has 15 devices at 19200 baud,
Max Info Frames would be 4.

You may need to increase the result of the formula for controllers

that need to communicate many values to other devices.

9.2.2.1.5 Time Master

If the controller can be a BACnet Time Master, this screen lets you
confi gure how it sends time synchronization broadcasts.

Figure 24

Time Sync Mode - Tap in the number below that represents your
selection:

— 0 = No Broadcast - The controller will not act as Time

Master.

— 1 = Local Broadcast - If it doesn't already exist, a

BACnet address with network number and MAC address
length both set to zero is added to the controller's Time
Synchronization Recipients list found on the driver's
Device page in WebCTRL®. The controller will then send
time broadcasts only to controllers on its ARCnet or MS/
TP network.

Figure 23

Touch a fi eld to tap in the new number on the keypad.

— 2 = Global Broadcast - If it doesn't already exist, a global

address with network number set to 65535 and MAC
address length set to zero is added to the controller's
Time Synchronization Recipients list found on the driver's
Device page in WebCTRL®. The controller will then send
time broadcasts to all its connected networks.

Time Sync Interval - Enter how often local or global time
broadcast should be sent (1-9999 minutes). If Time Sync Interval
is set to zero, no time sync messages are sent.

If the controller looks through its Time Synchronization Recipient

List and fi nds an entry with MAC address length set to zero and
network number set to 65535, the controller's BACnet Time
Master mode is set for Global Broadcast. If there is no global
broadcast entry in the recipient list, the controller then looks for
a local broadcast address (MAC address length set to zero and
network number set to zero or to the same network number as
the module's). If such an entry is found, the BACnet Time Master
mode is set for Local Broadcast. Otherwise, the mode defaults to
Disabled/None.
