NOTES:
1. Compressor and blower motor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. 208-240 60 Hz units are wired for 208v operation. Transformer is energy
limiting or may have circuit breaker.
4. FP1 thermistor provides low temperature protection for water. When
using antifreeze solutions, cut JW3 jumper.
5. Refer to multiple protocol controller (MPC), LON, or TSTAT Installation,
Application, and Operation Manual for control wiring to the wire from
PremierLink controller to "Y" Complete C when motorized valve is not
used. Thermostat wiring must be "Class 1" and voltage rating equal to or
greater than unit supply voltage.
6. 24v alarm signal shown. For dry contact, cut JW1 jumper and dry con-
tact will be available between AL1 and AL2.
7. Transformer secondary ground via green wire with yellow stripe from "C"
terminal to control box.
8. Aquastat is supplied with unit and must be wired in series with the hot
leg to the pump. Aquastat is rated for voltages up to 277v.
