Connect Rrv912 And Rrv918 Heating Circuit Controllers - Siemens Synco living QAX913 Mounting And Commissioning

After the battery charge test, an actuator previously connected
checks its settings as a lead controller (master) or lag controller
(slave). For lead controller settings, the LED blinks 3 times red/green,
for lag controller settings, the LED remains dark. Afterwards, the de-
vice assumes Normal operation.
If the room temperature is acquired with the built-in sensor of a radia-
tor control actuator, the control actuator, whose sensor is to be used,
must be connected first. The sensors of the other radiator control ac-
tuators of a room are not considered.
The binding LED on the device blinks green and goes out on successful bind-
ing with the central apartment unit.
If binding with the central apartment unit is unsuccessful, flashing of
the LED goes to blinking after 1 minute (status indication for unbound
operation).
After successful connection, the radiator control actuator restarts and auto-
matically starts self-calibration (see page 62).
The device is now connected and performs normal operation.
Calibrate the radiator control actuator
After successful connection of the control actuator, or after changing the bat-
teries, the SSA955 automatically starts the calibration process. This ensures
that the actuator is optimally matched to the radiator valve with which it is
used. During calibration, the LED blinks green.
The SSA955 informs the central apartment unit if calibration was successful. If
successful, the SSA955 automatically switches to control mode.
If unsuccessful, the LED flashes red. Retrigger calibration by pressing briefly
the function button.
Trigger manual calibration from the central apartment unit for all radia-
tor control actuators assigned to a room:

Connect RRV912 and RRV918 heating circuit controllers

The heating circuit controllers are automatically switched on as soon as power
is applied.
The LEDs are tested. All LEDs light up for one second. The mains LED lights
up when the unit is ready to operate.

Press the function button on the radiator
control actuator. The LED lights up in ac-
cordance with the battery charge (green:
Bat. ok, red: Bat not ok). Release the but-
ton when the LED starts blinking.
