The ventilation compensation
function does not operate when
summer night cooling function is
active.
6.7.2. Outdoor compensated ventilation
The ventilation compensation function adjusts the air volume depending on the existing outdoor temperature. It is
possible to enter four temperature points, with two of them defining winter conditions and the other two defining
summer conditions. When compensation start and end points for both winter and summer seasons are entered
(it is also possible to enter only one of them, example only winter compensation; in this case, the start and the
end points of summer compensation should be the same), the current ventilation intensity will be decreased in
proportion according to the outdoor temperature until it reaches the minimum possible ventilation level of 20 %.
6.7.3. Minimum temperature control
The minimum temperature control function forcibly reduces the supply and extract air flow set by the user when
the heater capacity available in the unit is insufficient and/or heat recovery does not ensure minimally possible
temperature supply to the room. The user can set a separate supply air temperature value so that when that value
is not achieved, the intensity of the ventilation unit starts to be reduced automatically. The air flow may be reduced
to the minimally possible ventilation intensity of 20 %.
In ventilation intensity control, this function has top priority over the func-
tions “Ventilation compensation according to the external temperature”
and “VAV”.
6.7.4. Override function
Override (OVR) control of the unit can be performed by the external contact (see Picture 5.3 b) or device (timer,
switch, thermostat, etc.). The received signal from the outside activates the OVR function, which ignores the cur-
rent operation modes of the unit and performs one of the selected actions listed below:
