Boost functions
14 % RH boost OFF Options are ON/OFF. This setting allows or prohibits
boosting according to the air humidity.
Summer / winter
limit temperature
4°C When the 24 hour mean temperature of outside air
is higher than this limit, boosted ventilation based
on the 48 hour mean humidity of extract air is taken
into use. If the 24 hour mean temperature is below
the value set here, a xed limit for boosted ventila-
tion is used.
% RH boost limit
value
45 % In winter mode (24 h mean temperature of outside
air is less than +4°C) boosted ventilation activates
when relative humidity of the extract air is higher
than this value.
Threshold value 48
hr % RH
15 % In summer mode (24 h mean temperature of out-
side air is higher than +4°C) boosted ventilation
activates when relative humidity of extract air is
higher than the 48 h mean humidity by the value
set here.
Max. supply air fan
speed
90 % The maximum allowed speed of the supply air fan
during humidity boosting.
Max. extract air fan
speed
90 % The maximum allowed speed of the extract air fan
during humidity boosting.
Rotor
dehumidication
OFF Options are ON/OFF. If allowed rotor dehumidica-
tion is active when humidity boosting is active and
the outside air temperature is below 0 °C.
15 CO2 boost OFF Options are ON/OFF. This setting allows boosting
of the fans according to the CO2 level. CO2 set-
tings require an external carbon dioxide transmitter
(optional extra).
CO2 boost limit
value
1000 ppm Boosting starts when the amount of CO2 exceeds
the value set here.
Max. supply air fan
speed
90% The maximum allowed speed of the supply air fan
during CO2 boosting.
Max. extract air fan
speed
90% The maximum allowed speed of the extract air fan
during CO2 boosting.
