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 located on the
upper right hand corner of the Power Center
PCB.
