Summer night cooling level
Summer night cooling level is defined by cooling need
detection limits and by lowering supply air temperature
setpoint. With preset values the user can select cooling
level: off, low, normal, high or full. Fresh air limit deter-
mines at which outdoor air temperature the function is
allowed.
By default the cooling need is defined by outside tem-
perature calculations and room temperature changes.
If advanced settings (User) is selected the 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:
off, low, normal, high or full.
If advanced settings (User) is selected the boost level can
be defined with room temperature boost limit and full
boost limit.
Select Use in Away mode to allow boost in Away mode.
Select Hood boost to open the damper on CASA Smart
cooker hood when summer night cooling is active.

5.1.2 Summer night cooling
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.
