5. The fan should now run at the selected speed. The
output can be verified by again referencing the Fan
Speed parameter.
The override will last for 5 minutes or until the Override
parameter is set to Disabled again.
Due to design considerations of the condenser section
of the wall unit, placement/clearance of the motor/fan
blade is critical to heat dispersal. Should a change of
motor or fan blade be necessary, see Figure 2.22 for
proper clearance adjustment.

High Pressure Transducer

The unit has a high side pressure transducer installed
on the liquid line between the condenser and electronic
expansion valve (EEV). The transducer is used for
system monitoring of high side system pressures.
This information is used to indicate when outdoor coil
cleaning is necessary based on outdoor conditions and
system pressures. The sensor is also used to adapt
the condenser fan speed for high and low ambient
conditions.
The high pressure input can be verified and adjusted
by:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to I/O Config;
press ENTER key.
4. Press UP or DOWN keys to scroll to Disch Pr
Sensor (C10); press ENTER key.
5. Verify the measurement displayed on screen is
accurate (see Figure 2.23).

6. If the measurement needs to be adjusted, apply an
offset value by pressing the ENTER key to scroll to
Offset.
7. Press UP or DOWN keys to to adjust the offset.
The update will not take effect until the cursor is
moved out of the offset parameter.
8. Once adjusted, the ESCAPE key several times to
return to Main Menu screen.

Discharge Temperature Sensor

The unit is equipped with a liquid line temperature
sensor to monitor the temperature of the liquid
refrigerant leaving the condenser and entering the EEV.
The temperature is measured with a 10k ohm NTC
thermistor.
The discharge temperature sensor can be verified and
adjusted by:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to I/O Config;
press ENTER key.
4. Press UP or DOWN keys to scroll to Disch Temp
Sensor (C3); press ENTER key.
5. Reference the Value to verify the temperature (see
Figure 2.24 on page 38).
6. If an offset needs to be applied, press ENTER key
to scroll to Offset.
7. Press UP or DOWN keys to change the offset to
desired value.
8. Press ENTER key to save.
9. Press ESCAPE key several times to return to Main
Menu screen.
