The radiator actuator is equipped with an automatic "window open detection" which is switched off at the factory. As soon as the radiator actuator detects a cooling by more than 0.3°C within 2 minutes, this is evaluated as "window open" and the thermostat is closed for 15 minutes. OPN is displayed on the radiator actuator and the setpoint temperature jumps to 4°C in the HomePilot. No entries can be made on the device for 15 minutes.
After 15 minutes, the temperature is reset to the last set temperature.
What is the exact definition of automatic "window open detection"?
