CONFIGURATION
This module is in charge of managing the motorised grilles that let the air flow enter the
zones, when corresponding. Please refer to the
Datasheet
, bundled with the original
device packaging and also available at
, for details on the technical
requirements to ensure compatibility with each particular grille model
It is important to take into account the following remarks:
Prior to any other action, it is necessary to set the proper grille voltage (24V
or 12V) in the
voltage switch
located on the front of the device.
ZoningBOX operates its outputs (and therefore the grilles) sequentially, i.e.,
one by one
– not at the same time.
Each output in ZoningBOX will control a sole zone and therefore a sole grille.
If two grilles are installed in the same zone, they will be also jointly
controllable by the same output, as long as they are the same model.
There are two control modes depending on
operation mode
enabled (see
section 2.1 for more details). When
Open/Close Mode
is enabled, grille
control is performed by measuring their current demands, which allows
detecting when they reach their target position (i.e., their end-of-stroke
position). Nevertheless, an additional time can be parameterised, to allow
further motion after the theoretical detection of the target position.
Furthermore, if
Positional Mode
is enabled, grill control is performed by
combining a current demand control plus a time control, which is based on
reaching a target point applying current a time proportional to the desired
position from a known position.
After a download or a bus failure, every output will be sent the order to open the grilles,
so their position synchronises with their status. During synchronisation, the grille status
will not be sent to the bus
– it will be sent once the grilles stop, depending on the initial
position that may have been parameterised.
