*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 203/1/60 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. 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 contact, cut
AL2 DRY (JW4) jumper and dry contact will be avail-
able 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.)
