14.5.21 Setpoint range

Set a limitation to the temperature setpoint range of both Cooling
and Heating operation.
INFORMATION
This function cannot be used when the indoor units are
controlled by a centralised controller.
INFORMATION
The default setpoint range limits for both Heating and
Cooling operation is [16°C-32°C], regardless of whether or
not "Setpoint range limitation" is enabled. It is not possible
to exceed these limits.
INFORMATION
The lower setpoint limit of the Cooling operation mode is
20°C, as per UAE Federal regulation UAE.S 5010-5:2016
clause 6, and UAE.S 5010-1:2016 clause 10.

14.5.22 Cooling/Heating masterhood

Set an indoor unit (or group of indoor units) as Cooling/Heating
master. When multiple indoor units are connected to an outdoor unit,
one of these units (or a group of indoor units, in case of group
control) needs to be set as Cooling/Heating master. The other units/
groups then become Cooling/Heating slaves, and are restricted in
their operation by the master (e.g. one outdoor unit does not allow
for one indoor unit to run in Cooling operation while another runs in
Heating operation).
When an indoor unit or group of indoor units is set as Cooling/
Heating master, the other units/groups automatically become its
slaves. To turn a slave unit into the master, first connect the app to
the controller controlling the currently active master and release it
from its masterhood, then set the (slave) unit as master.

14.5.23 Airflow direction range

Set the indoor unit airflow direction range according to the
installation location. This function is available for floorstanding indoor
units only. The maximum number of indoor units for which you can
make these settings is 16.

INFORMATION
For systems in which the indoor units run in simultaneous
operation, it is possible to set the airflow direction range of
individual indoor units by connecting the controller to each
indoor unit separately.
