Features 【High-quality material】: The mechanical thermostat controller switch is made of high-quality plastic material with fine workmanship, elegant appearance and durability. It is used in commercial and civil buildings and can control the coil motor and water valve of the central air conditioning terminal for heating and cooling 【Easy to Use】: The large data scale and adjustable buttons allow you to easily and quickly adjust and control the temperature. It has a surface mounting method that makes installation and disassembly easier. Adopt surface mounted method, easy and simple to install and remove 【Stable Performance】: The thermostat compares the measured temperature with the set temperature via a logic circuit, has stable performance and offers a temperature control range of 10℃ to 30℃. The measured temperature is compared with the set temperature by the logic circuit and the performance is stable 【Automatic Temperature Control】: When the relative temperature difference is more than 1°C, the fan or electric valve starts automatically. When the ambient temperature reaches the set temperature, the fan or electric valve closes automatically. 【Application】: The thermostat can control coil motors and water valves at the end of central air conditioning systems for heating and cooling. It is suitable for temperature control of fan coil units, electric valves, electric flaps and other terminal devices of central air conditioning systems. Suitable for temperature control of central air conditioning fan coil, electric valve, electric air valve and other terminal equipment 1.
