Features: - High-quality material: made with high-quality and durable plastic. - Easy to use: large data scale and adjustable buttons for quick and easy temperature adjustment and control. - Stable performance: comparison of measured temperature with set temperature through a logic circuit, providing a temperature control range of 10 ℃ to 30 ℃. - Automatic temperature control: automatic activation of fan or electric valve when the relative temperature difference is greater than 1 °C. Automatic shutdown when the ambient temperature reaches the set temperature. - Application: ideal for controlling coil motors and water valves in central heating and cooling air conditioners, as well as in central air conditioning fan coils, electric valves, and electric gates.
