3.3.2 Summer mode
Summer mode bypasses the ventilation unit's heat
exchanger when it needs to cool and the outdoor air is
colder than the room air. You then get cool outdoor air
in the room.
The heat exchanger takes care of the cool indoor air
during hot summer days. The capacity in summer mode
can be selected from a quick menu, and the ventilation
unit will then automatically determine the cooling.
If you wish to set the function's settings in more detail,
you select "User" mode on the settings menu.

Outdoor air limit determines at which outdoor air
temperature the function is permitted. Outdoor air start
limit determines the need of cooling.
If you select "Room air temperature limit", the need
of cooling is determined by the room air's temperature
exceeding the Room temperature start limit. The supply
air limit determines the supply air's minimum tempera-
ture. If you change the value, you must take the risk of
condensation on the pipes into consideration.
By changing the value Boost limit value room temp. dur-
ing AC boost you can determine at which room tem-
perature the ventilation shall start to variably boost.
Selecting Hood boost allows you to operate the damper
on a compatible cooker hood to the open position to
boost cooling.
Selecting In use in Away mode allows you to determine
whether ventilation boosting will be permitted in Away mode.
3.3.3 Cooker hood function
The cooker hood function balances the ventilation when
the cooker fan is used to help prevent excessive negative
pressure and improves fume extraction capability of the
cooker hood. This function enables you to boost the venti-
lation if necessary. The function starts automatically when
the damper in a Swegon CASA cooker hood is opened or
for a cooker hood defined I/O input (IO-control) receives
the signal and runs until the damper is closed.
The function is put into service from the Settings/Smart
functions/Cooker hood boost menu. The settings menu
is opened when the function is put into service.
