ELECTRICAL CONNECTIONS - DOMESTIC HOT WATER
CAUTION:
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
DANGER
- SHOCK HAZARD
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 heater 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 heater order.
1.
For Pool and Closed Loop Water Source Heat Pump applications, your heater 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 stage selector (Terminals 1&2). Then
jumper the remaining firing stages. For example, if your heater is a 162, you will jumper stage two. Then your heater 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 selector terminal
block in the heater. Stage 1 of the heater to stage 1 of the control. Stage 2 of the heater to stage 2 of the control, and so on.
Set the operating control at the setpoint in which you want the heater 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 heater in the instruction packet. The "TH" connections are for the remote tank
control through the heaters 24 volt transformer. DO NOT attach line voltage to the "TH" connection. Before starting heater
check to ensure proper voltage to heater and pump.
