can be done to the ventilation unit by random pressing of the
control panel buttons.
1. By default, the parental controls are turned off. Use
the
Arrow

2. Select
OK
.
3. The parental controls are now set.

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 outdoor 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 (rpm) will change
accordingly.
2. Measure and adjust the supply air flows from the
valves.
3. Press the
Right arrow
button

SETUP
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.
