Intermatic 156T4042A Fireman Switch for Pool/Spa Heater

Product Description

The Intermatic 156T4042A Fireman Switch is designed to provide coordinated control for pool and spa heaters, as well as filter pumps. This switch turns off a gas-fired pool or spa heater about 20 minutes before the filter pump shuts down. This reduces the potential for pounding and knocking caused by overheated water, while also reducing scale and lime deposits, which extends the life of the heater.
