NOTES:

1.Compressor thermally protected internally.

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

3.Transformer is wired to 208-v RED lead for 208-3-60 units. For 230-3-60, switch RED and ORG leads at L1 and insulate 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.Refer to microprocessor control, LON, or thermostat installation instruc- tions for wiring to the unit. Wire “Y” from thermostat to “Y1” Deluxe D

when motorized valve is not used. Thermostat wiring must be Class 1 and voltage rating equal to or greater than unit supply voltage. Heat/cool thermostats not compatible with motorized water valve.

6.24-v alarm signal shown. For dry alarm contact, cut JW4 jumper and dry contact will be available between AL1 and AL2.

7.Transformer secondary ground via green wire with yellow stripe from “C” terminal to control box.

8.Blower motor is factory wired for medium and high speeds. For any other combination of speeds, attach black wire to the higher of the two desired speed taps and the blue wire to the lower of the two desired speed taps.
