Water heating thermostat: This heating thermostat is used in hot water heating systems to control the opening and closing of the actuator installed on the water distributor, control the hot water flow and ensure that the room reaches the set temperature. Intelligent thermostats can help you save energy and feel comfortable. (Supports maximum current 3A, voltage 100-240V)
The thermostat has a built-in sensor that easily affects the temperature display by the self-heat of the device when switched on. For this reason, we have developed an intelligent temperature algorithm: after switching on the heater, the system automatically adjusts the display by about 2-3°C to counteract the effects of the thermostat's own heat. This adjustment usually stabilizes after half an hour. Please be patient, because the system automatically calibrates to ensure a more accurate temperature display.
Supports app remote control and voice control: simply connect to 2.4G WiFi to remotely control your WiFi thermostat underfloor heating water anytime and anywhere via your smartphone with the Smart Life/Tuya app. Supports Alexa and Google Home voice commands to control the thermostat. Turn your room thermostat underfloor heating on and off with voice commands.
