You can connect all devices of the same room, one after the
other, with no need for making additional entries on the central
apartment unit.
Now, switch on all RF components to be connected to the room – one
after the other – and connect them. The order of connection can be
freely selected. The only exception are the SSA955 radiator control
actuators and the RRV91... heating circuit controllers where the con-
trol actuator / control channel of the room connected first serves as
the lead controller / lead channel and the other control actuators /
control channels as the lag controllers.
Every connection made appears on the display and is confirmed by a
beep. When all devices of a room / switching group or device class
are connected, close the binding process by pressing the Menu/ok
button.

The room unit is automatically switched on as soon as the batteries

temperature.
Now, keep multifunction
button F on the room unit
depressed until the binding
symbol starts blinking. Then,
release the button again.
