Installation & Operation Manual
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.

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.
I t 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.
11. Connect power wiring to a 24 Vac power supply.
12. Turn on the controller's power.

6.3 Additional Information on Connecting Control Air
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.
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).
