Setting Subbase Switches
(If applicable)
The subbase system switch controls system
operation as follows:
HEAT—Heating system is controlled by the
thermostat. Cooling system is off.
COOL—Cooling system is controlled by the
thermostat. Heating system is off.
OFF—Both the heating and cooling systems
are off. If the fan switch is at the AUTO
position, the fan is also off.
AUTO—In a cooling only application, only
cooling operates. In a heating only applica-
tion, only heating operates.
The subbase fan switch controls fan operation
as follows:
ON—Fan operates continuously.
AUTO—Fan operates with cooling equipment
as controlled by the thermostat or with the
heating equipment as controlled by the
plenum fan switch. In electric heat, heat
pump, and fan coil systems, the fan is
controlled by the thermostat in heating and
cooling.
To switch positions, use thumb or index
finger to slide lever to desired position. For
proper circuit operation, stop switch lever in the
detent over desired function indicator mark.
