Mode of Operation

Power must be applied at all times. Upon closure of the thermostat, the delay on make period begins. Once complete, the load is energized and remains energized as long as the initiate switch is closed. When the thermostat switch opens, the delay on break period begins. Once complete, the load is de-energized and all time delays reset. If the initiate contact recloses during the delay on break period, the load remains energized and the delay on break period is reset. Removal of the input power resets all timing functions. Should the initiate contact open during the delay on make period, the delay on make period is reset to zero.

Installation

1. Disconnect power.

2. Connect terminals as shown in the wiring diagram below.

3. Select desired delay on break period.

4. Reapply power, check operation.
