Room temperature sensor***,
circuit 2
20 and 30 S10 Voltage signal (0–10 V) for
external control of desired
boiler temperature, circuit 1.
* 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 boiler / 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 also be available from a Remote
Control Unit (ECA 30 / 31). See 'Electrical connections, ECA
30 / 31'.
