Universal Air Conditioning Unit
Installation
Check all factory and field electrical connections for
tightness. Field-supplied wiring shall conform with the
limitations of 63 °F (17 °C) rise.
6 .7 Installing the Required Ambient
Temperature Sensor
I
Do not staple the sensor cables when mounting.
The ambient temperature sensor is located on the unit.
If relocation of the sensor is necessary, adhere to the
following guidelines:
• The ambient temperature sensor should be located in
a reliable return-air stream moving from the room to
be controlled to the air conditioner it is plugged into.
• locating the ambient temperature sensor on the back
of the air conditioner coil is not ideal and can result in
false readings for several reasons.
• it is best to locate the ambient temperature sensor
just inside of a return-air grille or passage.
• the standard cable length for the ambient
temperature sensor is 15 ft (2.1 m).
1. Find the coiled temperature sensor cable located on
the top of the unit.
2. Uncoil the cable and route to the electrical box.
3. Plug the cable into the port labeled “INSIDE” on the
circuit board located in the electrical box.
6 .8 Installing the Q3 Control
1. Plan the location of the display using the drill and
cut template (P/N 086812), included with the unit.
Choose a location that is easily accessible.
2. Drill a 1 in. (2.5 cm) hole in the planned location of
the Q3 control.
3. Install the Q3 control into the drilled hole.
4. Secure the Q3 control in place using the appropriate
size and number of screws.
5. Plug one end of the display cable (6-pin connector)
into the back of the Q3 control.
6. Connect the other end of the display cable into the
port labeled “CA” on the circuit board located in the
electrical box.
7. Ensure all cables are firmly connected.
6 .9 Installing the Optional Outside
Air Temperature Sensor
I
Do not staple the sensor cables when mounting.
1. plan the location of the outside air temperature
sensor.
2. install the outside air temperature sensor to
monitor temperature outside the cabin. outside air
temperature sensor cables are available in various
lengths. mount the sensor outside but not in direct
sunlight.
3. plug in the outside air temperature sensors’ two-pin
connector to the socket labeled “Outside Temp”
(white) located on the edge of the circuit board.
