* 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 outdoor temperature
sensor is common for both heating circuits.
**
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).
*** Only for room temperature sensor connection. The room
temperature signal can alternatively be available from a
Remote Control Unit (ECA 30 / 31). See 'Electrical connections,
ECA 30 / 31'.
Factory established jumper:
