A temperature controller is a device used to calculate the difference between a setpoint and a measured temperature. Temperature controllers provide on/off control for a range of applications like commercial heating, cooling, air conditioning, and refrigeration. Electronic temperature controllers come with digital displays, allowing programming to take just one finger. Products possess one and two stage capabilities and diagnostic detection. The wide setpoint temperature range and ability to select heating/cooling mode allow for a variety of uses.
