CO2 boosting and humidity boosting may activate
in mode 2 or 3. Additionally, humidity boosting may
activate also in mode 1.
If humidity boosting is not sufficient to remove excess
humidity from the premises, the rotor dehumidification
function can be activated. When humidity boosting is
active, rotor dehumidification activates automatically
if the outside air temperature is below 0 °C and the
functionality has been activated. This functionality
slows the heat exchanger rotation down, so creating
conditions for extracting greater volumes of humidity.
Fireplace/extractor hood mode
Fireplace mode control can be activated directly from
the control panel or by using a separate button (extra
equipment), which makes lighting of a fireplace easier.
Length of overpressure and supply and extract fan
speed can be set in the control panel. Fireplace mode
can be aborted from the control panel. Fireplace mode
lowers the extract fan speed and accelerates the supply
fan speed for 10 minutes (default setting).
NOTE
: Fireplace mode is only to be used as a
temporary help for lighting of the fireplace. The
combustion air for the fireplace must be brought
by other means than the ventilation unit.
The extractor hood mode is selected by selecting 0
min as the fireplace mode activation time (parameter
c12). This disables the fireplace mode selection from
the eWind operating panel. The extractor hood mode is
active as long as the extractor hood flap is open.
Manual boosting
Boosting or airing function is started directly from the
control panel. Boosting accelerates both fans for a pre-
defined time (default setting is 2 hours). Boosting can
be aborted from the control panel.
Temperature control
Heat recovery
Heat recovery is on when the supply air temperature
drops below the temperature set-point of the supply
air.
Cooling recovery
During summer, the heat exchanger turns fully on when
the outside air temperature is more than 1 °C higher
than the temperature of extract air. The heat exchanger
stops when the outside air temperature is lower than
the temperature of extract air. This will help in keeping
the room temperature cooler.
Heat recovery anti-freezing
The control phases the running of the heat exchanger
based on data from temperature measuring, thus
preventing freezing of heat exchanger. After the threat
of freezing has passed, the heat exchanger operation
returns to normal. Anti-freezing automation can be
initiated in the control panel.
Heat recovery efficiency
The efficiency of the supply and extract air heat
recovery is reported as percent value in the control
panel.
Alarms
In alarm modes the ventilation unit either stops
altogether (A alarms, for example fire alarm) or remains
running in a fault state where the fans runs at minimum
speed (so called AB alarms, e.g. when supply air is too
cold). Refer to the table "Troubleshooting" on page
40 for more information about the alarm.
