NOTES:
1.Compressor and blower motor thermally protected internally.
2.All wiring to the unit must comply with NEC and local codes.
3.Transformer for 208/230 v will be connected for 208 v operation. For 230 v operation, switch RED wire to ORG wire. Insulate open end of RED lead. Transformer is energy limiting or may have circuit breaker.
4.FP1 thermistor provides freeze protection for water. When using anti- freeze solutions, cut JW3 jumper.
5.Typical heat pump thermostat wiring shown. Refer to thermostat installa- tion instructions for wiring to the unit. Wire “Y” from thermostat to “Y” Complete C when a motorized valve is not used. “O” terminal is not used in cooling only applications. Thermostat wiring must be Class 1 and volt- age rating equal to or greater than unit supply voltage.
6.
7.Transformer secondary ground via green wire with yellow stripe from “C” terminal to control box.
8.Hot water generator pump only in models with hot water generation and internal pump option.
9.For auxiliary staging options, consult electric heat installation manual.
10.Fan motors factory wired for medium speed. For high or low speed, remove BLU wire from fan motor speed trap “M” and connect to “H” for high speed or “L” for low speed.
11.Aquastat is with unit and must be wired in series with the hot leg to the pump. Aquastat is rated for voltage up to 277 v.
