Essential Info

This time switch provides coordinated control for heater and filter pump operations. This two-circuit switch is designed to turn off a gas-fired swimming pool heater approximately 20 minutes before the filter pump shuts down. Eliminates the problem of pounding and knocking due to overheated water, reduces scale and lime deposits and extends the service life of the heater. The 24-hour dial allows up to 12 ON-OFF operations each day. One set of "ON" and "OFF" trippers are supplied with each switch. Minimum ON-OFF time is one hour.

This product is also available with a plastic enclosure, sold separately.
