Installation method for controlling electric heating with thermostat
1. All are controlled by digital temperature control instruments. The wiring method is also relatively simple. The normally closed point of the temperature control digital display instrument is connected to the coil circuit of the contactor in series. Namely high and total terminal. Connect thermocouples to meters 1 and 2. The neutral phase is connected to the 220V instrument power supply.
2. Users can set the indoor temperature according to their own needs, and the temperature control accuracy should be different according to different products. For a knob-type electric heating thermostat, you can turn the knob to set the temperature, and point the pointer to the temperature that the user needs. If the indoor temperature is lower than the temperature set by the user, the relay contact in the thermostat will close and start Drive heating equipment. And the heating indicator light will be on.
3. If the actual temperature of the room is consistent with the temperature set by the thermostat, the heating device of the thermostat will be disconnected at this time, and the indicator light that was originally on will be dimmed. And there is an external high temperature protection temperature sensor.
4. The protection temperature sensor is usually placed near the heating source, but the specific distance depends on the protection temperature of the electric heating thermostat. When the protection temperature sensor detects that the surrounding temperature of the sensor exceeds the protection temperature value, the thermostat turns off the heating output. However, when the sensor detects that the temperature around the sensor is lower than the protection temperature (45°C), the thermostat automatically resumes work.
