5.5Deactivation depending on outdoor temperature

5.5.1 OT deactivation value in rated operation

If the outdoor temperature exceeds the limit OT deactivation value in rated operation, the affected heating circuit is put out of service immediately. The valve is closed and the pump is switched off after t = 2 x Valve transit time. 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, during the warm season, the system is switched off at an outdoor temperature of 22 °C.

5.5.2 OT deactivation value in reduced operation

If the outdoor temperature in reduced operation exceeds the limit OT deactivation value in re- duced operation, the affected heating circuit is put out of service immediately. The valve is closed and the pump is switched off after t = 2 x Valve transit time.
