Features 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 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. 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 High sensitivity: The smart thermostat is equipped with an external probe,the detection is more accurate, and the temperature measurement is accurate. Installation Position: The heating thermostat should be installed on the wall in a place where the surrounding air flows freely.
