AIAS Room controller - installation and operation instruction | 17 / 26
Because of the default 0 s setting, switching operating modes
by depressing the Occupancy button functions differently: If the
Occupancy button is pressed when the controller is in the preset
operating mode or in Bypass mode, the controller will change
to Shutdown. If the Occupancy button is pressed in Shutdown
mode, the controller will switch to Bypass. After a congurable
period of time in Bypass (FS=2 hours), the controller will return
to the preset operating mode.
Occupancy detector
For local control of the operating mode between the preset ope-
rating mode and Bypass, an occupancy detector is connected.
When occupancy is indicated, the controller changes opera-
ting mode to Bypass. If you want to be able to enter the room
temporarily without activating Presence (to, for example, pick
something up) it is possible to congure a power-up delay. This
means that Presence is not activated until the power-up delay
has expired. The Presence delay can be set to a value between 0
and 60 minutes (FS=0 min).
In Bypass on presence, there is a switch-off timer, which means
that if there is no occupancy indication during this time (FS=10
mi), the controller will return to the preset operating mode.
Central control
Central control of the operating mode is also possible. By chan-
ging the variable RegioRemoteState, you can control the opera-
ting mode centrally according to the following table (there is a
variable list for central control in Part IV of this manual):
RegioRemoteState Description
0 Central operating mode Off
1 Central operating mode Unoccupied
2 Central operating mode Standby
3 Central operating mode Occupied
4 (Not used)
5 (FS) No central control
The occupancy button
When using central control (i. e. RegioRemoteState <> 5) and you
press the Occupancy button, the controller will change to Bypass
and stay in this mode for as long time as you have congured.
If you press the Occupancy button again when the controller is
in Bypass, the controller will change to Stand-by, regardless of
what has been set in the central control (RegioRemoteState).
When the controller is in Bypass and the Bypass time has run
out, the controller will change to the operating mode given by
RegioRemoteState. If RegioRemoteState equals 5 it will change
to the preset operating mode. If the controller is in Stand-by and
the central control is changed, the controller will change to this
new operating mode.
Occupancy detector
When central control is used and the occupancy detector is
activated, the controller will go to Bypass for a congurable time,
and thereafter return to the central operating mode.
Central command
Via central commands from a comprehensive system, for examp-
le EXO4, you can handle the controller in the same way as you
handle it locally via the Occupancy button, i. e. you can change
its operating mode to Off/Unoccupied (Shutdown) or Bypass.
Central commands should be regarded as events and can be
changed locally via the Occupancy button.
