* 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.
** Only for room temperature sensor connection. The room
temperature signal can also be available from a Remote
Control Unit (ECA 30 / 31). See 'Electrical connections, ECA
30 / 31'.
*** The flow temperature 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).
