4.3 Connecting (pairing) / separating base stations
If several base stations are used in one heating system, a maxi-
mum 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
• Time

Auxiliary function (load compensation)
The auxiliary function distributes the load of the heating circuit distributor evenly and in an opti-
mized way to all heating circuits used (load compensation). Thus, the load compensation allows
a more continuous flow of the heating medium. The distribution is performed in regular timely
intervals (pulse width modulation cycles (PWM cycles)) per heating zone, or heating zones per
thermostat.
In case of a change of the control parameters, the system performs a recalculation of the load
compensation in each case. The actuators connected to the respective heating zones regulate per
PWM cycle in different timely intervals in the scope of this cycle.
The load compensation cycle is firmly integrated into the Alpha 2 system and cannot be deacti-
vated, neither by a parameter nor by any kind of operation.
Note:
Due to the optimization of a PWM cycle during the load compensation, the actuators installed in
the system open and close at different times. This is also true if several heating zones are logged on
to a room control unit.
Note: The base station the components are connected to must be 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 “Master” 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.
