Probe Assignment
Some outputs of the controller (heaters, 0-10V
output and curtains) operate according to the av-
erage temperature measured by chosen tempera-
ture probes. You must assign temperature probes
to each of these outputs.
Room Temperature Sensors
Most cooling outputs (misting output, tunnel fans,
etc.) operate according to the average tempera-
ture in the room. You must select what tempera-
ture probes are used to measure the room tem-
perature.

Settings
This section explain how to select temperature
probes that are used to measure the room tempera-
ture and how to assign temperature probes that
are used to control/ monitor the following outputs:
• Heaters 1-4
• 0-10V output
• Natural ventilation curtains
A template is available at the end of
this manual to write down your selec-
tion of sensors.
Probe Set 2
In tunnel ventilation, some changes in airflow pat-
terns can distort the room temperature calculation.
For this reason, it is possible to make another se-
lection to measure the room temperature in tunnel
ventilation. The second probe set must be enabled
in the Installation Setup to use this function (see
section 4.5).

RH COMPENSATION
The controller offers different way to compensate
for high/low relative humidity (RH) levels in the
room. All compensation functions are explained
below. To use them, you must enable each desired
compensation function in section 4.6.
•
High RH Compensation
with Heating Outputs:
When RH levels are too high, the controller
can activate heating outputs in timer mode.
As RH levels increase, the controller in-
creases the On Time portion of the heating
cycle to compensate for the change. The
maximum compensated heating On Time is
reached when RH levels are 10% above the
RH Set Point.
•
High RH compensation with
cool cells & misting outputs:
If RH levels are too high, the controller can
stop the misting output and/or cool cell out-
put. Theses outputs are disabled when RH
levels reach the respective RH shutoff limit
of each output.
•
Low RH compensation
with misting outputs:
To compensate for low RH levels, the con-
troller can activate the misting output in
timer mode. The misting output starts when
RH levels decrease below the
Low RH Set
Point
.
