Typical control wiring schematics (cont)
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, 240-V (ORG) lead for 240/1/50 units, or
208-V (RED) lead for 208/1/60 units.
Rewire transformer L1 connection if voltage is
230-1-60 or 220-1-50, insulate unused lead.
4. FP1 thermistor provides freeze protection for
WATER. When using ANTI-FREEZE solutions,
cut JW3 jumper.
5. Refer to LonWorks
®
Installation, Application, and
Operation manual for control wiring to the unit.
Low voltage wiring must be “class 1” and voltage
rated equal to or greater than unit supply
voltage.
6. 24-v alarm signal shown. For dry alarm contact,
cut JW1 jumper. Dry contact will be available
between AL1 and AL2.
7. Transformer secondary ground via Complete C
board standoffs and screws to control box.
(Ground available from top 2 standoffs as
shown.)
