Wall Thermostat Enable: A wired wall thermostat can be connected to the unit. To connect a
wall thermostat to the unit, this DIP switch must be moved to the Wall Thermostat Enable position
in order for the wall thermostat to function.
•
Set-point Temperature Limits: Provides a restricted range of temperature control.
•
Heat and Cool Fan CON/CYC DIP switches: Allows the fan to operate in continuous or cycle
mode while the unit is in heating or cooling mode.
o
Continuous (CON): Allows fan to run continuously, circulating air even when the temperature
setting has been satisfied. This switch helps to maintain the ambient temperature closer to the
thermostat setting.
o
Cycle (CYC): This setting allows the fan to cycle on and off with the compressor or electric
heater. The fan stops a short time after the set point is reached.
