Misting Output
The controller can control one misting output. When
the room temperature reaches the start tempera-
ture of the output, mist units are activated and run
in timer mode according to their minimum timer
(Min On Time & Min Off Time).
Then, as tempera-
ture rises, a gradual transition is made from the
minimum timer towards the maximum timer
(Max
On Time & Max Off Time)
. The second mist timer
is fully used when the room temperature reaches
the
Maximum Temperature
parameter setting. The
misting output is disabled when the temperature
falls below a user-defined value. It can also stop
when humidity levels are too high (see RH Compen-
sation in chapter 10).
Start and stop temperatures of the misting output
are related to the set point. This means that when
the set point changes, these temperatures are ad-
justed accordingly.
Operating time range
The user can specify a time range during which
the output can run. This allows deactivating the
misting output at night for instance.

Static Pressure Set Points
The high & low static pressure set points are the
limits above and below which pressure-based air
inlets (such as vent doors or tunnel doors) open or
close. The controller allows using up to 3 different
set point groups; each group starts at a user-
defined fan stage. Refer to the Installation Setup
section of this manual to enable the desired num-
ber of pressure set point groups.

Accessible if at least one pressure-based air inlet output is
enabled in the Installation Setup (sec. 4.5).

The following parameters are displayed:
Static pressure set points must be
defined separately for each program
of the controller.
Low / High SP#x Set Point
Set the low and the high static pressure set
point of each group.
Use at stage
Set the fan stage at which each pressure
set point group starts being used. Note that
the 1
st
group automatically starts in mini-
mum ventilation (or at stage 1 if minimum
ventilation is not used). Also note that the
controller automatically limits the stage at
which each group starts so that the set point
groups are activated one after the other (in
numerical order).
