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.
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.

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.
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 (rpm) 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 modes.
   

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 airflow adjustment, the airflow must be measured through the air volume adjustment menu (see “Save and restore settings”). This ensures that the unit settings are optimal for the  adjustment of the airflows.

VENTILATION MODES

Four ventilation unit modes
At home
Use this mode when the dwelling or the premises are occupied.
Away
Use this mode when the dwelling or premises are unoccupied, e.g. during a trip or other long absence.
Boost
Use this mode to increase the ventilation rate, e.g. when there are more people than usual in the dwelling or elsewhere on the premises.
Fireplace mode
Use this mode when, for example, you are making a fire in the fireplace. The mode is primarily used to create momentary overpressure in the dwelling.

TIP
Using the At home, Away, and Boost modes according to need saves energy.
IMPORTANT
Prolonged overpressure can result in damage to the structures of the building.

Symbols for ventilation modes
The following symbols are used on the main displays of the modes:

off.
| The mode in use is either At home, Away, or Boost. The week clock is on.

| The Fireplace mode is used. The week clock might be turned on.
