3.4 Heater Connection
The heater connection section applies to all
heaters or heat pumps with thermostatic circuitry
of 24 VAC or less (see pages 15 thru 17 for brand
specific installation).
NOTE If you are connecting a heater with thermostatic
circuitry of 120 VAC or greater, do not connect
to the green, 10-pin Terminal Bar. Instead
connect the heater to a high voltage relay in the
Power Center and plug the spare relay into the
Electric Heater relay socket on the back of the
Power Center PCB.

1. Connect two #14 gauge wires, designed for
use in hot environments, to the #1 and #2

terminal bar in place of the factory installed
wire loop.
3. Do not disconnect high limit or pressure
switches.
4. Turn the heater thermostat(s) to maximum
