How to Test a Mechanical Room Temperature Controller

1. Set temperature test: When setting the temperature, observe whether the thermostat can switch to the set temperature normally. If it cannot switch to the set temperature, the machine is faulty and needs to be repaired or replaced.

2. Thermometer indication test: Observe the indication of the thermometer equipped with the controller to determine whether the machine is working normally. If the thermometer indicates too hot or too cold, the temperature is not being controlled and needs to be repaired or replaced.
