For a normally-opensensor, attach the Yellow wire to the remaining sensor terminal. Tape back the Brown wire. See Figure 3.

4.Attach the Red wires to the 24 Vac terminals. Important Most controllers with sensor connections also provide a control switch to bypass sensor operation if necessary. Check the switch setting to make sure it is not in the Bypass or Active position.

Wiring Procedure II (no sensor feature)

1.Locate the valve common wire terminal, generally labeled “C” or “COM”, and remove all common wires for valves, pump relay, etc.

2.Attach the White wire to this terminal.

3.Splice the Brown wire to the common wires and insulate the connection using a wire nut or electrical tape. Tape back the Yellow wire. See Figure 4.

4. Attach the Red wires to the 24 Vac terminals.
