Silent Mode - Zennio MAXinBOX FC 0-10V VALVE User Manual

2.5.3.2 SILENT MODE

The Silent Mode function permits restricting the maximum fan speed during the
automatic fan speed control. This guarantees that the fan noise level remains low.
To that end, one specific binary object is provided to permit entering / leaving the silent
mode when desired, as well as the corresponding status object. Note that entering the
silent mode implies switching to the automatic fan speed control, in case the
manual speed control is active.
The fan coil module will also leave the silent mode if an alarm or an order with a higher
priority (a switch-off, a purge, or a heating/cooling mode switch). Please refer to
Annex I: Fan Coil Priorities.
On the other hand, entering the manual fan speed control when the silent mode is
active will make the device ignore the latter, although it will be taken into account again
after returning to the automatic fan speed control.
Note: the silent mode function cannot be enabled in parameters if the automatic fan
speed control is not available.
ETS PARAMETERISATION
The Silent Mode screen is accessible after enabling such function (see section 2.5.3). It
contains the following parameter:
Maximum Speed Allowed in Auto Mode: sets the maximum speed
permitted for the fan while the silent mode remains active (as long as the fan
speed control remains automatic).
The silent mode can be entered or left by sending the values "1" and "0" (respectively)
to the binary object "[FCV1] Silent Mode". On the other hand, "[FCV1] Silent Mode
(status)" will show whether this mode is currently active or not.
