Features Convenient Building Temperature Controller: Used in commercial and civil buildings, the mechanical temperature controller can control the coil motor and water valve of central heating and cooling air conditioning terminal. HOW IT WORKS When the relative temperature difference is more than 1℃, the electric fan or valve is automatically started, and when the ambient temperature reaches the set temperature, the fan or electric valve is automatically closed. Wide Application Our thermostat is suitable for temperature control of central air conditioning fan coil, electric valve, electric air valve and other final equipment. Stable performance: the measured temperature is compared with the temperature set by the logic circuit, and the performance is stable. Easy Surface Installation Adopt surface mounting method, easy and simple to install and remove.
