3.3 Switching and setting options
3.3.1 Ventilation volume
Using the switch shown, the Xcell 350V EC BP is adjustable in the following three ventilation positions:
Position 1 - To be used in the event of absence. Ventilation at the minimum required volume
Position 2 - Normal position.
Position 3 - High position. Use this position for cooking and showering and whenever extra ventilation
is required.
The current position is shown on the unit’s display.
• The current ventilation position cannot be altered on the Xcell 350V EC BP display, but only using the
switch.
• After cooking and showering, keep the Xcell 350V EC BP in the highest setting for a little while to
ensure the rapid extraction of surplus moisture and odours; refer also to ‘time delay’ on the following
page.
3.3.2 Comfort temperature
This is the temperature at which the bypass is regulated. Set this to your desired temperature. The
Xcell 350V EC BP will work to the temperature set.
• Regulation occurs automatically. If the outside temperature is too high (e.g. during the day), the
bypass will not be activated.
Setting comfort temperature:
• Press button
for 2 sec.
• The current comfort temperature is shown in the display
• Set the desired temperature using the
or
buttons.
• Press
to confirm the chosen temperature.
The Xcell 350V EC BP will now show the current ventilation position again
3.3.3 Supply off
On warm summer days, windows and/or doors are often left open. In principle, automatic supply is then
not needed. Once the supply feature is switched off, your Xcell 350V EC BP operates as an extractor
fan.
Set supply off:
• Press button
for 2 sec. and the supply fan is switched off.
• You have deactivated the balanced ventilation and heat recovery functions. Switch them back on as
soon as it gets colder in order to prevent energy wastage and unnecessary expense.
• Press button
for 2 sec. and the supply fan is switched on again. The balanced ventilation and
heat/cold recovery functions (with opened bypass) are again available.
3.3.4 Dirty filter alarm
The Xcell 350V EC BP filters both air flows (supplied and extracted air). The filters must be regularly
cleaned or replaced.
In this event, the alarm symbol ‘FiL’ ‘tEr’ will flash in the display.
Filter contamination rates depend on where you live. You can set this in the P24 menu:
‘normal’ (setting 0)
‘rural’ (setting 1)
‘urban’ (setting 2)
The ‘FiL’ ‘tEr’ alarm is displayed earlier for the ‘urban setting, followed by the ‘normal’ setting and then
the ‘rural’ setting.
Setting the dirty filter alarm:
Menu P24:
• Press the [menu] button
• Press the [ok] button
