NOTES:

1.Compressor and blower motor thermally protected internally.

2.All wiring to the unit must comply with NEC and local codes.

3.Transformer is wired to 460 v (BLK/RED) lead for 460/3/60 units. Transformer is energy limiting or may have circuit breaker.

4.FP1 thermistor provides freeze protection for water. When using antifreeze solutions, cut JW3 jumper.

5.Typical thermostat wiring shown. Refer to thermostat installa- tion instructions for wiring to the unit. Thermostat wiring must be Class 1 and voltage rating equal to or greater than unit sup- ply voltage.

6.Factory cut JW1 jumper. Dry contact will be available between AL1 and AL2.

7.Transformer secondary ground via Deluxe D board standoffs and screws to control box. (Ground available from top two standoffs as shown.)

8.Aquastat is supplied with unit and must be wired in series with the hot leg to the pump. Aquastat is rated for voltages up to 277-v.

9.Blower motor is factory wired for medium and high speeds. For any other combination of speeds, at the motor attach the BLK wire to the higher of the two desired speed taps and the BLU wire to the lower of the two desired speed taps.

10.Optional LON wires. Only connect if LON connection is desired at the wall sensor.

11.Blower motor is factory wired for high and low speeds. No other combination is available.

12.The 460-v units using an ECM (electronically commutated motor) fan motor, modulating HWR (hot water reheat), and/or an internal secondary pump will require a neutral wire from the supply side in order to feed the accessory with 265-v.
