Basic fan settings
IMPORTANT
Adjust the air flows according to the values specified in the
ventilation plan. It is recommended that the air flows be
adjusted without having to choke the air flows at the valves.
This is the most energy-efficient set up.
First, set both values as close to the ideal value as possible
by looking at the supply and extract air fan curves. If the
ratio between the air flows is very high at first, the ventilation
unit may have to carry out extra defrosting cycles in sub-zero
temperatures, thus making adjustment of the air flows more
complicated. Check the air flows by measuring them at the
valves, and fine-tune the percentage values as required.
NOTE
If the outside air is extremely cold (below -10°C on an
aluminium cell or below -3°C on a plastic cell), the ventilation
unit may have to defrost the heat recovery cell. If this
happens, the
Defrosting
icon will be displayed on the control
panel. The air flows cannot be adjusted during defrosting.
Adjusting the supply and extract air flows
1. Use the
Plus
and
Minus
buttons to set the supply air fan
ratio as a percentage of the maximum output ratio. The
fan speed (1/min) will change accordingly.
2. Measure and adjust the supply air flows from the valves.
3. Press the
Right arrow button.
4. Use the
Plus
and
Minus
buttons to set the extract air fan
ratio as a percentage of the maximum output ratio. The
fan speed (1/min) will change accordingly. Measure and
adjust the extract air flows from the valves.
5. Select
OK
. Supply and extract air flow settings are now
complete.
6. Record the set percentages in the measurement log.
Do not change the output ratio between the supply and
extract air fans once the settings are complete. The same
ratio is also used in the Away and Boost profiles.
TIP
You can browse the
Basic fan settings
by using the
Right
arrow
button.
NOTE
If the use of the ventilation unit has been started before air
flow adjustment, we recommend that the factory settings of
the ventilation unit be restored before adjustment is started
(see “Save and restore settings”). This ensure that the unit
settings are optimal for adjusting the air flows and that any
settings made during the adjustment are saved as setup
settings. Any later changes will be saved as user settings.
Both the setup and user settings can be restored later even
if the settings had been modified later.
IMPORTANT
The supply and extract air
settings have been completed
by a specialist during setup
of the ventilation unit. These
settings should be changed
only when the ventilation
unit is reconfigured, and not
at any other time. Changing
the ventilation settings so
that overpressure is created
can result in damage to the
structures of the building.
