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.
