NOTES:

1.Compressor and blower motor thermally protected internally.

2.All wiring to the unit must comply with NEC and local codes.

3.Transformer is wired to 460 v (BLK/RED) lead for 460/60/3 units,

575 v (GRY) lead for 575/60/3. 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.Check installation wiring information for specific thermostat hookup. Refer to thermostat installation instructions for wiring to the unit. Thermostat wiring must be “Class 1” and voltage rating equal to or greater than unit supply voltage.

6.24-v alarm signal shown. For dry alarm contact, cut JW4 jumper and dry contact will be available 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.)

8.Aquastat is supplied with unit and must be wired in series with the hot leg to the pump. Aquastat is rated for voltage up to 277 v.

9.Blower motor is factory wired for high and low speeds. No other com-

bination is available.

10.The 460-v units using an ECM (electronically commutated motor) fan motor, modulating HWR, and/or an internal secondary pump will require a neutral wire from the supply side in order to feed the acces- sory with 265-v.

NOTES:

1.Status LED (GREEN) Slow Flash - Controller In - Fault Retry Mode. Fast Flash - Controller in Lock- out Mode. Slow Flash = 1 Flash per every 2 seconds. Fast Flash = 2 Flashes per every 1 second.

2.Fault LED (RED) flashes a code representing last fault in memory. If no fault in memory code 1 is flashed.

3.Cycles appropriate code, by cycling alarm relay in the same sequence as fault LED.

4.Alarm relay closes after 15 minutes.

5.Alarm relay cycles. Closed for 5 seconds and open for 25 seconds.
