0-10V Fan Output

A 0-10V output can be used to activate
supplementary fans. Refer to the User Setup
Menu to enable this kind of output.
A 0 -10V fan output can operate as an
independent ventilation stage and use its
own temperature settings. The graph below
shows how this type of output works.

• Below the start temperature: The output
follows a timer and runs at its minimum
speed;
• At the start temperature: The output oper-
ates continuously at its minimum speed, and
starts increasing in speed as the temperature
increases;
• At the maximum temperature: The output
reaches its maximum intensity;
• Above the stop temperature: The output
is deactivated.
To enable a independent 0-10V fan output,
set the operating mode of this output to
"Ventilation" in the User Setup Menu.
The start temperature of the independent
0-10V fan output can be set as an absolute
value or it can be related to the set point: this

means that when the set point changes, the

must follow the set point or not.
