Fig. 22 — 50PEC Unit Remote-Mounted Thermostat with Deluxe D Controller Wiring
*Optional wiring.
NOTES:
1. Compressor and blower motor thermally
protected internally.
2. All wiring to the unit must comply with local
codes.
3. Transformer is wired to 115-V (WHT) lead
for 115/1/60 units; 265-V (BRN) lead for 265/
1/60 units; or 208-V (RED) lead for 208/1/60
units.
For 230/1/60 operation, switch the RED and
ORG leads at L1 and insulate the RED lead.
Transformer is energy limiting or may have a
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 Installation Instructions
for wiring to the unit.
6. 24-V alarm signal shown. For dry alarm con-
tact, cut AL2 DRY (JW4) jumper and 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.)
