This setting must be considered if this controller is a slave.
Under normal conditions, your system is not frost protected if your
setting is below 0 °C or OFF.
For water-based systems, a setting of 2 °C is recommended.
If the outdoor temperature sensor is not connected and the factory
setting has not been changed to 'OFF' , the circulation pump is always
ON.
The valve is fully closed as long as the pump is not switched on.
