Timer —
If timer-based relays are assigned to
some fan stages (sec. 4.8), set the
“On Time”
and the
“Off Time”
of each timer-based relay.
On and Off Times can be adjusted from 0 to
99 minutes in increments of 15 seconds.
Seasonal Temperature
6.2.2.2.
Changes
If the outside temperature compensation on
the bandwidths of stages 1 and 2 is used, you
must specify at what outdoor temperature
winter and summer start.

6.2.3. 0-10V Ventilation Outputs
The controller has two 0-10V outputs that
can either be used to control heat lamps,
heat mats, inlets or fans. To operate these
outputs, the controller refers to the average
temperature reading of their assigned tem-
perature probes (sec. 4.7.3).
This section explains how 0-10V ventilation
outputs work.
0-10V ventilation outputs start at their mini-
mum intensity when the average temperature
of their probes reaches the start temperature.
They increase in intensity as the tempera-
ture increases; 0-10V outputs reach their
maximum intensity when the temperature
rises to the
“Maximum Temperature”
parameter
setting.

0-10V Mode: Automatic / Manual:
You
can manually control the intensity 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 intensity of the output.

Mode —
Set the operating mode of the 0-10V
output: select
“Automatic”
if you want the con-
troller to control the output or select
“Manual”
to
specify the intensity of the output 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 temperature
is adjusted by the same amount. (refer to sec-
tion 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.
