Review on TPI ET9SRTS Voltage Terminal 50° 90°F by Bernardino Suazo

Designed and made with good materials. not thin and not light. Works great with a ceiling exhaust fan used to dissipate the heat generated by the two refrigerators in the pantry. The only downside is the degree range between on and off... The setting of the switch-on temperature is accurate, but the temperature range from on to off seems a bit wide. But perfectly acceptable for my purposes. This is a "cooling only" thermostat, meaning it will turn off when the temperature drops to a certain temperature. This is not for heaters!
