S10
Voltage signal (0 - 10 V) for
external control of desired
flow temperature in 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.
** Only for room temperature sensor connection. The room
temperature signal can also be available from a Remote
Control Unit (ECA 30 / 31). See the Mounting Guide (delivered
with the application key) for specific connections.
*** The 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 when two DHW tank temperature sensors
are required.
