Vent door / Inlet 1 is already displayed.
Press Vent door / Inlet 2 to display parameter
settings of the second inlet.
* This menu is accessible if at least one vent door
(inlet) output enabled in the Installation Setup (sec-

Make sure you have selected a static-
pressure-based vent door (inlet). Refer
to section 4.5 to set vent door (inlet)
functions.
2. Set the following parameters:
(Refer to the previous section to get further informa-
tion on these parameters).
Wind Effect Delay —
Select what delay must
elapse before moving the vent door (inlet)
when the pressure level exceeds a pressure
set point.
Pre-opening Delay —
Set the time that is
required to pre-open the vent door (inlet)
before activating minimum ventilation fans.
Adjustable from 0 to 120 seconds.
6.6. 0-10V Air Inlet
The first 0-10V output of the controller can ei-
ther be used to control an air inlet or variable-
speed fans. This output operates according
to the average temperature of its assigned
temperature probes (see sec. 4.7.3).
A 0-10V air inlet works exactly the same as
a potentiometer-based air inlet but does not
need to be calibrated.
0-10V Mode: Automatic / Manual
You can manually control the opening of a
0-10V output by using the manual control
mode. While this mode is used, the control-
ler stops controlling the output and lets you
choose the inlet opening.

2. Set the following parameters:
0-10V inlets work as potentiometer-
based inlets. Refer to section 6.5.2 to
see how they work and to get information
about the following parameters.
Mode —
Set the operating mode of the 0-10V
output: select
“Automatic”
if you want the
controller to control the output according
to specified parameter settings below or
select
“Manual”
to specify the inlet opening
manually.
Opening —
This is the current opening of the
air inlet. This opening can be changed when
the manual mode is enabled above.
Closed —
This is the position of the air inlet
during the
“Off Time”
portion of minimum
ventilation cycles. Set this position to the
desired value.
Stage #x —
Assign an inlet opening (in %) to
each fan stage in use.
Over-Opening Settings:
Opening —
Assign an inlet position to the
over-opening stage.
Bandwidth —
Set the temperature range
over which the inlet gradually opens from the
position associated with the last fan stage
towards the over-opening position (see graph
in section 6.5.2).
