21 and 30 S9 ECL 310 only:
Not used
20 and 30 S10 ECL 310 only:
Voltage signal (0 - 10 V) for
external control of desired
flow temperature
* 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 alternatively 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).
**** This sensor is used if only one tank temperature sensor is
required.
Factory established jumper:
30 to common terminal.
