FA Series

Thermostat Connection

NOTE: Different thermostats operate according to their particular features. Refer to the thermostat’s

speciﬁcations for details.

Each FA Series heater requires a single stage thermostat rated for 24VAC to operate. The heater

comes standard with a terminal strip for making the thermostatic connections, located on the back

panel. The thermostat terminal designations are as follows:

R: 24VAC Power

W: Call for Heat

G: Continuous Fan

C: Common for 24VAC Power

24VAC is supplied from an internal 40VA transformer. Do not supply 24 Volts to the terminal strip. A

minimum of 18 AWG low voltage thermostat wire must be used for connecting the thermostat to the

heater. Follow the ﬁeld wiring diagram in Figure 3.4 for wiring to a typical single-stage thermostat.
