fresh air start
limit
can be changed which effects to the cooling detec-
tion limits.
If “
Room air temperature limit
” is selected, the cooling
need is based on fixed
room temperature start limit
.
The supply air temperature setpoint is defined with
supply air limit
during function. If the limit is changed,
the risk of condensation on the pipes must take into
consideration.
Summer night cooling stepless boost
Summer night cooling effect is enhanced with boosting
the ventilation if supply air temperature is relatively low.
With preset values the user can select boosting level:

Automatic Summer night cooling detects cooling need
and decreases the supply air temperature, if possible,
and boosts the ventilation. Temperature control is
applied with heat exchanger efficiency control and with
external cooling battery (accessory). Summer night cool-
ing is most efficcient when the outdoor air temperature
is relatively low.
