The STC-200+ thermostat is a device that controls the power supply status of a wired heater or cooler or output alarm. It has just one relay and can be used for refrigeration, heating, or alarm mode. The thermostat has a function menu that allows you to set the temperature range, temperature hysteresis, protection delay time for the compressor, lower limit for SP setting, upper limit for SP setting, and calibration of real-measured temperature.

Wiring Diagram

Before using the thermostat, refer to the wiring diagram in the user manual to ensure that it is properly connected to the heater or cooler.
