Anti-freeze function: When the room temperature drops to the set value, the thermostat will automatically activate the heating device. When the room temperature is 2°C higher than the set value, the heating device will automatically turn off.

Open window detection function (OWD function): When OWD is enabled in the parameter settings, the system will automatically stop heating when it detects a sudden drop in room temperature (2°C in 15 minutes by default). This is usually caused when a window or door is opened without turning off the heating device. The heating device will return to its previous operation within 30 minutes. Pressing the button will stop the OWD function.
