4.2 Connecting (pairing) / separating base stations
If several base stations are used in one heating system, a maximum
of seven units can be coupled (paired) for the exchange of global
system parameters via radio or system bus (syBUS). The radio range
of the base station must be observed for the radio connection. If the
radio range is insufficient, pairing must be performed with the syBUS.
Communication is done according to the master/slave principle.
Requirements and status messages are exchanged between the units.
The master unit centrally controls the directly connected functions/
components:
• CO input/output
(if the pilot function is activated)
• Boiler output
• Pump output
Note: The base station the components are connected to must be

4.1 First commissioning
4 Commissioning
The base station is in installation mode during the first 30 minutes after switching on the mains
voltage. The target and actual temperatures are compared in this mode, all other functions are
deactivated. If the actual temperature is below the target temperature, the output allocated to
the respective room control unit is activated at the base station. This allows signalling at the base
station without delay, enabling the control of the allocation between the room control unit and the
output of the base station.
¾
Switch on the mains voltage.
9
The base station initialises the installation mode for 30 minutes.

If the base station is parameterised for NC actuators, all heating zones are activated for 10 minutes in
order to unlock the first-open function of the NC actuators.

The power LED (operation display) lights up continuously.
configured as master. Further base stations can only be paired with the master.
The pairing of base stations is done as follows:
¾
Press the syBUS button of the base station to be configured as master for three seconds in order to start
the pairing mode.
9
The LED “syBUS” flashes.
9
For three minutes, the pairing mode is ready to receive the pairing signal of another room control unit.
¾
Press the syBUS button of the base station to be configured as slave two times consecutively for one
second, in order pair it with the master.
9
The paring mode ends automatically after the process has finished.
9
The LED “Master” lights up permanently at the master base station.
9
The LED “Master” flashes if the base station has been configured as slave.
¾
Repeat the process for paring another base station.
