Product Description
The 156T4042A Fireman Switch is a heater control kit that coordinates operation between a pool or spa heater and the circulation pump. It is designed to turn off a gas-fired pool or spa heater roughly 20 minutes before the filter pump stops, helping prevent overheated-water effects and reduce scale buildup while supporting longer heater service life.
Key Benefits
- Coordinated control for pool and spa heaters and filter pumps
- Turns off gas-fired heater about 20 minutes before pump shutdown to prevent water pounding
- Reduces scale and lime deposit formation
- Rated 10 A, 250 VAC max
