In the water outlet pipe or on the pipeline (equipped with a temperature sensing wire), the temperature is controlled by two metal materials *-and then through a temperature sensor and a temperature controller. "When the water temperature is higher than the set temperature-the heater does not work-on the contrary-the water temperature is lower than the set temperature-the heater works." In this paper, the function and principle of temperature controller will be discussed in depth to help readers better understand the equipment.

The function of temperature sensitive line

The temperature sensing wire directly senses the temperature of water and transmits the temperature signal to the temperature controller.

Composition of temperature controller

In addition to the output and input of the power supply (generally 24V), the thermostat also has two connection ports, which are respectively connected with the temperature sensing line (divided into+pole and-pole).

Control of heater

When the water temperature is higher than the set temperature, the heater does not work; On the contrary, when the water temperature is lower than the set temperature, the heater works.

Brand of temperature controller

The brands of thermostat are Omron and Shenshi.
