Intermatic Pool Pump Timer with Fireman's Switch - 230V
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.
The Time Switch eliminates the problem of pounding and knocking due to overheated water, reduces scale and lime deposits and extends the service life of the heater. Works on Jandy Laars, Raypak or Hayward heaters. One set of "ON" and "OFF" trippers supplied with each switch. 204V-250V. Saves money and equipment.
