  • Engineered to be more sensitive and accurate than conventional thermostats, APCOM water heater thermostats are the most popular in the industry. Their patented design encapsulates the bimetal thermostat sensor, protecting it from the temperature changes of other components. This feature means you get a thermostat with enhanced temperature sensitivity for accurate, reliable system control.
  • APCOM thermostats are remarkably easy to install. The wiring terminals feature "tear drop" holes that enter into the bind head screw terminal, making it easier to lock the wire into place. This speeds the assembly process, and helps ensure that connections are made properly. In addition, our limit control/safety override feature automatically trips at 180 degrees to improve safety (±5°).

  • Made In the U.S.A.
