Select a higher number to increase the fan speed, a lower number to decrease the fan speed.

Select a higher number to increase the fan speed, a lower number to decrease the fan speed.
x
Use for installations where more than one system operates from the same power source. Different
staging delays allow compressors to start at different times when the power is interrupted. Stage the
units at least five seconds apart.
x x Ambient Temperature
Calibrates the sensor to display the correct room temperature reading.
The setting increments are in °F even when the control is set to display °C.

Refer to "Fail Safe Levels" on page 20.
Applies to display firmware #40 and older.

x x OFF
Set the built-in voltmeter circuit that monitors the AC input voltage prior to each cooling or heating
cycle when set to 95 VAC or 195 VAC.
• For 100–120 VAC input power, set to OFF or 95.
• For 208–240 VAC input power, set to OFF or 195.
x OFF
Select the parameter setting for the de-icing feature depending on whether you are using the
optional inside air temperature sensor or the display built-in temperature sensor.
• If using an optional inside air temperature sensor, set this parameter to 1 to turn the de-icing feature
ON, or to OFF to disable.
• If using the display built-in temperature sensor, choose one of the two selectable behavior modes:
– 1: assumes the display sensor may be reading the room temperature as much as 5 °F (3 °C)
greater than the actual evaporator temperature (standard).
– 2: for more extreme installations - assumes the display sensor may be reading the room
temperature as much as 7 °F (4 °C) greater than the actual evaporator temperature.
• The setting of 2 should only be used if a setting of 1 does not prevent evaporator ice from forming.
x OFF
Set this parameter setting when the optional pump sentry water sensor is installed to monitor the
condenser coil temperature and to shut down the pump and compressor when the coil temperature
rises above the programmed value. This sensor is plugged into the H2O OUT sensor jack on the
control board.
Program a temperature between 100 °F and 150 °F (38 °C and 66 °C), depending on seawater
temperature and the system type. Refer to the sensor installation instructions. The setting increments are
in °F even when the control is set to display °C.
