Intermatic 178T24 Freeze Protection Thermostat (Replacement Thermostat Assembly)
Intermatic 178T24 is a genuine freeze protection thermostat replacement used with Intermatic freeze protection controls and timers to help protect pool and spa equipment and plumbing from freeze damage. When the outdoor/ambient temperature drops below the user-adjustable setpoint, the thermostat signals the system to turn the pump (and commonly the heater circuit, depending on wiring/configuration) on to keep water moving and reduce freeze risk.
