* If the outdoor temperature sensor is not connected or the
cable is short-circuited, the controller assumes that the
outdoor temperature is 0 (zero) °C.
**
The sensor must always be connected in order to have the
desired functionality. If the sensor is not connected or the
cable is short-circuited, the motorized control valve closes
(safety function).
*** This sensor is used if only one tank temperature sensor is
required.
**** The sensor must always be connected in order to have the
desired functionality.
