Effortlessly manage your pool or spa heating system with the Intermatic Heater Control (Fireman) Switch Kit (ITM156T4042A). This kit not only streamlines your heating control but also incorporates the intelligent design of the 156T4042A Fireman Switch, providing coordinated control for your pool/spa heater and filter pump.
Designed to enhance efficiency, the 156T4042A Fireman Switch is crafted to turn off a gas-fired pool/spa heater approximately 20 minutes before the filter pump shuts down. This strategic timing eliminates issues like pounding and knocking caused by overheated water, reducing scale and lime deposits. The result is an extended service life for your heater, ensuring optimal performance and longevity.

With durability and reliability at its core, the Intermatic Heater Control (Fireman) Switch Kit provides a hassle-free solution for maintaining a comfortable and efficient pool or spa environment. Take command of your heating system and enjoy the benefits of coordinated control for enhanced performance and longevity.
