0-10V Ventilation Outputs

The controller has a 0-10V output which can ei-
ther be used to control an air inlet or variable-speed
fans. To operate this output, the controller refers
to the average temperature reading of probes that
are assigned to the 0-10V output (see sec. 4.7.3).
This section explains how a 0-10V ventilation out-
puts work.

STOP T°
START T°
The 0-10V ventilation output starts at its minimum
intensity when the average temperature of its
probes reaches the start temperature. The fans
increase in intensity as the temperature increases;
they reach their maximum intensity when the tem-
perature rises to the Maximum Temperature pa-
rameter setting.
0-10V Mode: Automatic / Manual
You can manually control the intensity of the
0-10V output by using the manual control mode.
While this mode is used, the controller stops con-
trolling the output and lets you choose the intensity
of the output.

Installation Setup (section 4.5).
• Set the following parameters:
Mode: Set the operating mode of the 0-10V
output: select "Automatic" if you want the
controller to control the output or select
"Manual" to specify the intensity of the out-
put yourself.
Current output: This is the current intensity
of the output. This intensity can be modified
while the manual mode is enabled above.
Start temperature: Set the start tempera-
ture to the desired value. This temperature
can be set as a fix value (absolute) or it can
be related to the set point: this means that
when the set point changes, the start tem-
perature is adjusted by the same amount.
(refer to section 4.5 to specify if the start
temperature of the 0-10V follows the set
point or not).
Minimum & max speeds: Set the minimum
and maximum speeds of the 0-10V output.
The maximum speed must be greater than
the minimum speed.
Maximum output at: Set the temperature
at which the output reaches its maximum
speed (this parameter must be set to a
greater value than the start temperature).
Stop at: This is the temperature below which
the 0-10V output stops.
