One line voltage “HUM” 1/4” spade terminal is provided on
the furnace control board. Any humidifier rated up to one
amp can be connected to this terminal with the neutral leg
of the circuit being connected to one of the provided neutra
terminals. If a humidifier rated at greater than one amp is
connected to this terminal, it is necessary to use an external
relay. See Figure 49 for control board configuration. This
terminal is energized in the heating mode when the
combustion air inducer is operating.
Install the room thermostat according to the instructions
provided with the thermostat. See Figure 46 for thermostat
designations. If the furnace is being matched with a help
pump, refer to the FM21 installation instruction or appropriate
dual fuel thermostat instructions.
