INFORMATION
▪ The connection of optional accessories to the indoor
unit might cause changes to some field settings. For
more information, see the installation manual of the
optional accessory.
▪ For details about the specific field settings of each type
of indoor unit, see the installation manual of the indoor
units.
▪ Outdoor unit field settings can only be configured via
the outdoor unit PCB. For more information, see the
installation manual of the outdoor unit.
▪ Field settings that are not available for a connected
indoor unit are not displayed.
15.5.23 Duty rotation
Activate Duty rotation to let the indoor units operate alternately (one
indoor unit alternately inactive), this to increase system lifespan and
reliability.
Duty rotation is designed for units operating in critical applications
(e.g. in server rooms that require lots of cooling). In these cases, the
system is equipped with an extra backup unit. Activating Duty
rotation then allows for:
▪
Rotation
: because the system is equipped with more units than
are required to provide the heating/cooling load, one of the units
can remain inactive during normal operation. After a set time (i.e.
"Rotation cycle time"), the inactive unit will start operation, and a
previously active unit will become inactive (i.e. duty rotation).
Because the units only operate alternately, the lifespan of the
system increases.
▪
Backup
: having a backup unit allows for system redundancy. If an
active unit goes into error, "Duty rotation" makes sure an inactive
one takes over.

INFORMATION
This function can only be used when the indoor units are in
group control.
INFORMATION
▪ To let the backup unit reach its cooling/heating
capacity, an overlap period is included in which all
indoor units are active. For more information, see
"Indoor unit field settings" on page 18
1E-7).
▪ The rotation order depends on the set unit number. For
instructions on how to change the indoor units' unit
number, see
"15.5.18 Unit number" on page 32
15.5.24 Test operation
Perform a test run on Sky Air indoor units. During the test run, the
indoor units cycle through various operation modes and functions to
check if they are ready for operation.
When
Only activate the test operation after the following is completed:
▪ Installation of refrigerant piping;
▪ Installation of drain piping;
▪ Connection of electrical wiring.
Typical workflow
Performing a test operation typically consists of the following stages:
1
Activating the test operation (Madoka Assistant app),
2
Testing the indoor unit functions according to the instructions
set out in
"To perform a test operation" on page 34
,
3
Deactivating the test operation (Madoka Assistant app),
4
Checking the error history for possible errors.
5
If applicable, fixing the causes of those errors.
6
Repeating the procedure if required.
INFORMATION
Also see the installation manual of the indoor unit and
outdoor unit.
