1. Make the cut-out for the display panel to measure
2.9 in. (74 mm) wide by 2.2 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.
6 .3 Installing the Optional Sensor
Hardware
This section describes where and how to mount
additional sensors.
6 .3 .1 Remote Air Temperature
If the display cannot be mounted in a proper location,
install this optional sensor to monitor the cabin
temperature. An installed remote air sensor will override
the display’s built-in sensor.
I
The sensor’s distance from the air conditioner must
be within the 7 ft (2.1 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-left corner of the circuit board.
6 .3 .2 Outside Air Temperature
Install this optional sensor to monitor the outside air
temperature (OAT).
I
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.
6 .3 .3 Humidity/Temperature
Combination
Install this optional sensor to monitor the relative
humidity of the cabin.
I
The control board automatically detects the this
sensor and immediately starts measuring humidity.
1. Mount the sensor in the same location as the ambient
air temperature sensor.
2. Plug the sensor’s 6-pin connector into the inside
temperature socket at the edge of the circuit board.
6 .3 .4 Service Sensor
–
DX Only
Install this optional DX sensor to monitor the condenser
coil temperature.
I
This sensor must be enabled with the Pump Sentry
feature. See section “Understanding the DX
Operational Settings” on page 21.
1. Mount the sensor at the condenser coil outlet and
install insulation around it.
2. Plug the sensor into the H2O OUT plug #P5.
6 .3 .5 Seawater Temperature
–
DX Only
Install this optional DX sensor to monitor the temperature
of the seawater feeding the air conditioning unit.
1. Mount the sensor in direct contact with the copper
pipe, using thermal mastic to ensure a good heat
transfer.
