1、Wiring Free: The temperature controller is a wiring free temperature controller, which is suitable for decoration without reserved buried wires and holes. The receiving power is placed next to the fan coil. The control panel of the temperature controller can be placed at will. 2、Use: The thermostat is applied to the temperature control of the water system or air system. By comparing the ambient temperature with the set temperature, it can control the fan coil unit, electric valve, electric ball valve or air valve at the end of the air conditioning system to achieve the purpose of comfort and energy conservation. 3、Microcomputer Control Technology: The temperature controller adopts microcomputer control technology, which is elegant in design and easy to use. The panel buttons can select the cooling, heating, ventilation modes, and set the required temperature and wind speed. 4、Large LCD Display: The temperature controller has a large LCD display to clearly display data, which is easy to read, use and practical. 5、High Reliability Chip: The temperature controller adopts high reliability chip, which has strong anti interference ability and high reliability. 1 x Temperature Controller1 x Power Control Board2 x Screws 1 x instructions Item Type: Fan Coil ThermostatMaterial: ABSGross Weight: 208g/ 7.3ozProduct Size: 8.6x 8.6x 1.5cm/ 3.4x 3.4x 0.69inMaterial: ABSVoltage: 220vBattery Model: 2PCS button battery, CR2032, shipped without batteryTemperature Sensing Element: NTC thermistorConsumable Power: ＜ 1wTemperature Setting: 5 ℃ to 35 ℃Display Range: - 9 ℃ to 99 ℃Load Power: ＜ 200wDisplay: LED display
