Fig. 17 — 50PEC Unit Manual or Auto Changeover with Complete C Controller Wiring
LEGEND NOTES:
1. Compressor and blower motor thermally pro-
tected 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. For remote sensor, position jumper J1 on upper
2 pins.
6. For F position, position jumper on both pins.
For C, position jumper on one pin.
7. Transformer secondary ground via Complete C
board standoffs and screws to control box.
