Calibration of the radiator control actuator
After successful connection of the control actuator, or after changing
the batteries, 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 whether calibration
was successful. If successful, the SSA955 automatically switches to
control mode.
If unsuccessful, the LED flashes red. By pressing briefly the
multifunction button, calibration can be newly triggered.
From the central apartment unit, manual calibration of all radia-
tor control actuators assigned to a room can be triggered:
Main menu > Heating > Room X > Room settings >
Actuator calibration
Connect RRV912 and RRV918 heating circuit controllers
The heating circuit controllers are automatically switched on as soon
as power is applied to them.
Then, the LED's are tested. All LED's lights up for one second. The
mains LED lights up as soon as the controller is ready to operate.
If, thus far, none of the heating controller channels has been con-
nected, the connection LED flashes. The other LED's remain dark.
When you press the binding button, the status of the individual
channels is indicated. The LED's of the channels already con-
nected light up, those of the channels not connected remain
dark. When releasing the button, the heating circuit controllers
returns to normal operation after 10 seconds. When a channel
is selected, the connection LED indicates the status of the re-
spective channel.
