Connecting RF components
Notes
RF components are assigned to rooms or functions.
On the central apartment unit, the required rooms must be configured
beforehand (refer to page 16), the required functions activated and
the mode of transmission set to "Via RF" or "Via RF / S-Mode" (refer
to page 19 ff.).
If, by mistake, a device has been connected twice, the central
apartment unit ignores the second connection, delivers an
error message and a beep.
After all devices have been connected, you can check the
number of channels and the connected device types on the
device list. Missing devices can also be added later and de-
vices not needed can be removed.
Connect RF room components
The following RF components can be assigned to a room:
• Room unit QAW910
• Room temperature sensor QAA910
• Radiator control actuator SSA955
• Heating circuit controller RRV91...
(only heating circuit actuators)
• Door / window contacts wave AP 260
RF components are to be connected room by room. Inform the cen-
tral apartment unit which room you want to assign RF room compo-
nents:
Main menu > Commissioning > RF connections > Rooms >
Room X > Connect device:
Confirm entry on submenu "Connect device" by pressing the Menu/ok
button. To make the connection, press the binding button on the de-
vice to be connected.
