Temperature sensor
1.
Before mounting the control panel, consider the location. The display panel's built-
in air sensor provides excellent room-air temperature sensing when properly locat-
ed and installed. For the sensor location on the display panel, see
stalling the Display Panel.
2. Ensure the following requirements are met when mounting the display panel:
• Install the display on an inside wall, slightly higher than mid-height of the cabin.
• Select a location with freely circulating air where the temperature sensor can best
sense average temperature.
• Select a location within 15 (4.57 m) of the air conditioner to accommodate the
length of the display cable (custom lengths are available).
• Avoid installing the display in direct sunlight, near any heat-producing appliances,
or in a bulkhead where temperatures radiating from behind the panel may affect
performance.
• Avoid installing the display in the supply air stream, above or below a supply air or
return-air grille, behind a door, in a corner, under a stairwell, or any place where
there is no freely circulating air.
NOTE If you cannot mount the display in a suitable location, install the op-
tional inside air temperature sensor.

1.
Make the cut-out for the display panel to measure 2.91 in (74 mm) wide by 2.20 in
(56 mm) high.
2. Plug the 8-pin connector end of the display cable into the upper-right socket on the
circuit board in the electric box.
3. Plug the other end to the back of the display panel.
4. Secure the display panel to the bulkhead using the four screws provided.
5. When the display is securely mounted, place the bezel over the display frame and
snap into place.

Installing the optional sensor hardware
This section describes where and how to mount more sensors.
5.3.1
Inside air temperature sensor
If the display cannot be mounted in a proper location, install this optional sensor to
check the cabin temperature. The installed sensor will override the display built-in
temperature sensor.
NOTE The sensor's distance from the air conditioner must be within the 7
(2.13 m) standard cable length.
1.
Mount the sensor in the return-air stream behind the opening of the return-air grille.
2. Plug the 6-pin connector cable into the inside jack #J3 in the upper-le corner of
the circuit board.
5.3.2
Outside air temperature sensor
Install this optional sensor to check the outside air temperature.
NOTE The sensor's cables are available in various lengths.
1.
Mount the sensor outside, but not in direct sunlight.
2. Plug the cable into the OAT plug #P6.
5.3.3
Room temperature/relative humidity sensor
Install this optional sensor to check the relative humidity of the cabin.
NOTE The control board automatically detects the this sensor and immedi-
ately starts measuring humidity.
1.
Mount the sensor in the same location as the optional inside air temperature sensor.
2. Plug the sensor's 6-pin connector into the inside temperature socket at the edge of
the circuit board.
