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.
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.
