Electric Heating Only / Emergency Heat (For
Heat Pump Units Only)
This setting is typically used for Emergency Heating.
Wall Thermostat Enable
A wired wall thermostat can be connected to the unit.
If it is, this dipswitch must be moved to the Wall
Thermostat Enable Position, before the wall
thermostat will begin control.
Heat and Cool Fan CON/CYC Dip--switches
Allows the fan to operate in continuous or cycle
modes while the unit is in heating or cooling mode
(continuous or cycle):
CON
(Continuous)
Allows fan to run continuously, circulating air even when the
temperature setting has been satisfied. This switch helps to
maintain the room temperature closer to the thermostat setting.
CYC
(Cycle)
This setting allows the fan to cycle on and off with the
compressor or electric heater. The fan stops a short time after
the temperature setting is satisfied.
Setpoint Temperature Limits
Provides a restricted range of temperature control.
Room Freeze Protection
If unit senses a room temperature below 40
˚
F
(4.4
˚
C), the fan motor and electric strip heat will turn
on and warm the room to 50
˚
F (10
˚
C). The fan stops
a short time after the temperature is satisfied.
NOTE: Configuration DIP switches are only read
during a power up cycle.
See Table 5 –
Dip Switch Functions
for functions of
each dip switch position.
