Features Application: Used in commercial and civil buildings, it can control coil motor and water valve of central heating and cooling air conditioning terminal. Installation: Adopt the surface mounting method, easy and simple to install and remove. Functionality: the measured temperature is compared with the temperature set by the logic circuit and the performance is stable. Operation: When the relative temperature difference is more than 1℃, the electric fan or valve will start automatically, and when the ambient temperature reaches the set temperature, the electric fan or valve will automatically close. Suitability: suitable for temperature control of central air conditioning fan coil, electric valve, electric air valve and other final equipment. 1.
