Starting up the system
CAUTION
Before starting up the system, make sure:
▪ The indoor and outdoor unit wiring is completed.
▪ The switch box covers of the indoor and outdoor units
are closed.
The controller gets its power from the indoor unit. It will start up as
soon as it is connected. For the controller to be operable, therefore
make sure the indoor unit is powered on.
Once the controller is powered, it will automatically start up. If it is
the first and only controller that is connected to the indoor unit, it will
automatically get designated as master controller. For a second
controller to get designated as slave controller, manual action is
required. For instructions, see

INFORMATION
It is only possible to use a master and a slave controller of
the same type.
INFORMATION
In case digital input adapter BRP7A5* is part of the
system, it is not possible to connect and designate a
second controller. Connecting a second controller when
the system already contains the adapter, will cause the
adapter to go in error.
INFORMATION
If a slave controller does not display the home screen 2
minutes after its designation, turn off the power and check
the wiring.
INFORMATION
After re-designating a controller, the system requires a
power reset.
INFORMATION
Slave controllers do not support all functions. If you cannot
find a function on a slave controller, check for it on the
master controller.
