Feature:1. High Temperature Protection: Smart thermostat has a control electric heating device, which can be applied to control floor heating devices. The built in sensor measures the indoor temperature, and the external sensor measures the floor temperature or the heating equipment temperature to control high temperature protection, preventing the heating device from burning due to high temperature.2. Convenient Control: Floor heating controller has two control modes, manual mode and automatic mode. The automatic mode can control different temperature heating according to the user's set time period. Manual mode does not need to be divided into time periods, and users can freely choose, which is convenient and saves time.3. Programming Mode: In the shutdown state, press and hold the mode key M and clock key for 5 seconds to enter programming mode. You can switch parameters through the mode key. After entering programming mode, press the mode key to adjust the hour, then press the mode key to adjust the minute, and press the mode key again to adjust the temperature.4. High sensitivity: The smart thermostat is equipped with an external probe,the detection is more accurate, and the temperature measurement is accurate.5. Installation Position: The heating thermostat should be installed on the wall in a place where the surrounding air flows freely.Specification:Item Type: Programmable Digital ThermostatMaterial: ABSModel: MH1822DTemperature Sensor: NTCControl Temperature Accuracy: 1Power Consumption: <1wVoltage: AC85 to 250VFrequency: 60HzLoad Current: 16ATemperature Setting: 5 to 50 Keys: Touch keysLow Temperature Protection Function:In the shutdown state, the thermostat will self heat when the temperature is below 5 and stop heating when the temperature is above 7.Package List:1 x Programmable Digital Thermostat1 x Temperature Humidity Probe2 x Screws1 x English ManualNote:Installation location should not be affected by other heat sources such as sunlight, air flow through windows and doors or exterior wall temperatures
