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.

The Control Air M communicates through a Rnet connection. The Control
Air M is intended for use with a single WSHP. It can be wired using the
instructions in section 6. The Control Air M+ communicates through a
BACnet MS/TP connection. The Control Air M+ is intended for use with up
to 50 WSHP's on an exisiting network.
5.1 Recommended Wiring Scheme
Connect this wire: To this terminal on the Control Air M:
Red 24 VAC (R)

6.1 Communicate Using a Tablet Through Virtual Control Air M and M+
In lieu of using the module to interface with the controller, a connection
may be established at the local access port of the controller to perform
test and balance operations or to make changes to any device on the networ k.
6.2 To Wire and Mount the Control Air M/M+
1. Remove the backplate from the Control Air M/M+
a. Hold the Control Air M/M+ as shown in the picture below.
b. While fi rmly pressing the 2 tabs on top of the Control Air M/
M+, pull on the backplate with your index fi nger until the
backplate releases from the Control Air M/M+.
Figure 5
2. Pull the communication cable, power cable, and external
thermistor wiring (if applicable) through the large hole in the center
of the backplate.
3. Partially cut, then bend and pull off the outer jacket of the Rnet
cable(s). Do not nick the individual wire insulation.
4. If wiring 1 cable to the Control Air M/M+, cut the shield wire off at
the outer jacket, then wrap the cable with tape at the outer jacket
to cover the end of the shield wire. If wiring 2 cables in a daisychain confi guration, twist together the shield wires, then wrap the
shield wires with tape.
5. Strip about 0.25 inch (0.6 cm) insulation from the end of each
wire.
6. Connect wiring to the Control Air M/M+ as shown in Figure 6.

6.3 Additional Information on Connecting Control Air
CAUTION: ELECTRIC SHOCK HAZARD
Allow no more than 0.06 inch (1.5 mm) bare
communication wire to protrude. If bare
communication wire contacts the cable's foil shield,
shield wire, or a metal surface other than the
terminal block, the device may not communicate
correctly.
Figure 7
M/M+ to a Controller
Connect the Control Air M/M+ module (or Android tablet if using Virtual
Control Air M/M+) to the serial port on the DDC controller as indicated
below.
CAUTION: ELECTRIC SHOCK, INJURY HAZARD
If the equipment is used in a manner not specified
by the manufacturer, the protection provided by
the equipment may be impaired.
Mounting
The Control Air M/M+ must be mounted within the building interior. You
can mount the Control Air M/M+:
In a panel with the controller or on the panel door
On a wall up to 500 feet from the controller
Wiring
The Control Air M/M+ requires a 24 Vac power supply. It is not powered by
the Rnet.
7. Attach the backplate to the wall or panel. If mounting in or on a
panel:
a. Drill two 3/16 inch (4.8 mm) pilot holes in the panel.
b. Attach backplate using pan head 6-32 x 3/8" to l/2" long
machine screws. Do not overtighten screws to prevent
damage to plastic housing.
It is recommended to use Loctite 220 on screw threads if the
Control Air M/M+ will be subject to vibration.
8. Attach the Control Air M/M+ to the backplate:
a. Place the bottom of the Control Air M/M+ onto the backplate
by aligning the 2 slots on the Control Air M/M+ with the tabs
on the backplate.
b. Push the Control Air M/M+ onto the backplate until the tabs
at the top of the Control Air M/M+ snap onto the backplate.
9. Turn off the controller's power.
10. Connect the other end of the Rnet wiring to the controller's Rnet
port or to a zone sensor.
- Insert the shield wire with the ground wire into the controller's
GND terminal.
- Use the same polarity throughout the Rnet or MS/TP.
CAUTION: ELECTRIC SHOCK HAZARD
The Control Air M/M+ can share a power supply
with the DDC controller as long as you:
1. Maintain the same polarity.
2. User the power supply only for DDC
controllers.
You can also wire an external 10 kOhm, Type II thermistor to the Control
Air M/M+. See External sensor resistance requirements (Table 6, page
13).
11. Connect power wiring to a 24 Vac power supply.
12. Turn on the controller's power.
