When the outdoor temperature falls below this value (less 0.5 °C hysteresis), heating operation is restarted immediately. With the default settings, this means that, at night, the system is switched off at an outdoor tem - perature of 10 °C to save energy. Nevertheless, remember that the system requires some time in the morning to heat up the bui[...]
