RH COMPENSATION

Relative Humidity (RH) Compensa-
tion on the Minimum Ventilation
Speed
The controller can compensate for high
humidity levels by increasing the minimum
ventilation fan speed. As the RH level rises,
the controller increases the minimum venti-
lation speed to compensate for the change
and reaches the maximum compensated
speed when the RH level is 10% above the
RH set point.
In addition, if the controller is already operat-
ing with the minimum ventilation mode when
this compensation starts, it will then make
the minimum ventilation fans run continu-
ously rather than cycled.

* These menus are accessible if the RH Compen-
sation function is set to "Ventilation" in the User
Setup Menu.
3. Set the following parameters:
(The parameter adjustment process is explained
in section 3.2 on page 8).
Humidity setp — Set the humidity level
over which the minimum ventilation speed
starts increasing. This set point ranges
from 40 to 100% of humidity.
RH speed comp — Set the speed that
must be added to the regular minimum
ventilation speed when the humidity level
exceeds the set point by more than 10%.
