Connecting a Pump Start Relay

CAUTION: Never connect an auxiliary pump starter directly to the controller. A 24 VAC relay, rated at 0.50A maximum current draw, must be used to connect the controller to the pump starter circuit.

1.Route a wire pair from the pump start relay into the controller housing.

2.Connect one wire to the valve common COM (8). Connect the remaining wire to the PUMP/MV (9) as shown below.

Jumper Wire

24 VAC Pump Start Relay Valve Common Wire

CAUTION: If the pump does not have an auto- matic pressure control switch, prevent pump damage due to “dead-heading,” by connecting a jumper wire from any unused station terminal to a station terminal with a valve wire connected.

Note: Refer to “Pump Control and Well Recovery” section

8on page 28 for important pump circuit control information.

Connecting the Plug-in Transformer

CAUTION: Do not plug the transformer into an electrical outlet until all of the wiring procedures have been completed.

1.Route the cable from the transformer (13) through the small opening provided in the base of the housing. Wrap the cable around and through the restraining post as shown below.

2.Connect one transformer cable wire to each terminal labeled 24 VAC (10). The wires can be connected to either terminal.

Note: The display will begin flashing 12:00 a.m. Press any button to stop the display from flashing.
