Heater Time Clock - 220 Volt

These Intermatic time switches provide coordinated control for heater and filter pump operations. The two-circuit switch is designed to turn off a gas-fired swimming pool heater approximately 20 minutes before the filter pump shuts down. It 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 daily. The hinged door provides easy access to the industry's most reliable timers, and the lockable latch makes the enclosure tamper proof. 240V. Dimensions: 9-3/8"H x 5-1/2"W x 3-5/8"D
