ELECTRICAL CONNECTIONS - DOMESTIC HOT WATER

CAUTION:

DANGER

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

-SHOCKHAZARD

Make sure electrical power to the heater is disconnected to avoid potential serious injury or damage to components.

Installer action is required to electrically enable your Hi-Delta boiler to operate after making the power conections. You must make a connection on Terminal Block #3 for temperature control connections. This will be done based on the controller option selected with your boiler order.

1.For Pool and Closed Loop Water Source Heat Pump applications, your boiler should be configured to operate in an ON/ OFF firing mode. This means that you will connect a single-pole control to stage one of TB-3 (Terminals 1&2). Then jumper the remaining firing stages. For example, if your boiler is a 652, you will jumper stage two. Then your boiler will either be on at full fire, or it will be off.

2.For multi-stage controller connections, connect each stage of the control to the corresponding stage of TB-3 in the boiler. Stage 1 of the boiler to stage 1 of the control. Stage 2 of the boiler to stage 2 of the control, and so on.

Set the operating control at the setpoint in which you want the boiler to maintain. Ensure that the sensing bulb of the control is at the point in the system that will best maintain the temperature you want. For example, when you are heating a tank of water, you want the operating control sensor bulb in the tank.

Consult the wiring diagram shipped with the boiler in the instruction packet. The "TH" leads are for the remote tank control through the boilers 24 volt transformer. DO NOT attach line voltage to the "TH" leads. Before starting boiler check to insure proper voltage to boiler and pump.
