This switch saves you the trouble of having to manually run to the heater to turn it on and off. When the switch is off, power enters the switch from the terminals, flows to the heater and energizes it; when the switch is on (filter pump off), the circuit is interrupted and the heater will not be energized. When installing this switch, turn off the power. The 156T4042A Fireman's Switch provides coordinated control of any pool/spa heater and filter pump. It is designed to shut off a gas-fired pool/spa heater approximately 20 minutes before the filter pump shuts off. This eliminates shock and knock problems caused by overheating the water, reduces scale and lime deposits, and extends the life of the heater.
