NOTES:
1.Compressor and blower motor thermally protected internally.
2.All wiring to the unit must comply with NEC (National Electrical Code) and local codes.
3.
4.FPI thermistor provides freeze protection for WATER. When using ANTIFREEZE solutions, cut JW3 jumper.
5.Typical heat pump thermostat wiring shown. Refer to thermostat installation instructions for wiring to the unit. Thermostat wiring
must be “Class 1” and voltage rating equal to or greater than unit supply voltage.
6.Factory cut JW1 jumper and dry contact will be available between AL1 and AL2.
7.Transformer secondary ground via Complete C board standoffs and screws to control box. (Ground available from top two stand- offs as shown.)
8.Suffix 1 designates association with lead compressor. Suffix 2 designates association with lag compressor.
9.For water valve option, DIP switch 2.1 ON, 2.2 OFF, 2.3 ON.
