5.8 Service menu

Use this function to configure the following sub-menu items.
10 - Level 1 Supply air
Level 1, which is the lowest speed, is usually used when
there is nobody home. Both fans can be configured inde-
pendently of each other for all levels so that the air flow in
the supply air and in the extract air is equal, which pro-
vides optimal operation.
The adjustment of the system must be performed with
specialised air measurement equipment and can be per-
formed without the use of the main regulating damper.
It is not recommended to configure the air flows without
expert advice. Incorrect configuration can lead to major
energy consumption or unpleasant indoor climate.
Setting option: between 0 and 100 %.
Factory setting: 30 %.
11 - Level 2 Supply air
Level 2 is the recommended speed of the system in order
to provide the optimal indoor climate and it should be
adjusted to the ventilation requirement of the dwelling.
Setting option: between 0 and 100 %.
Factory setting: 50 %.
12 - Levels 3 and 4 Supply air
Level 3 is the highest speed that can be configured. It is
used e.g. if there are many guests or there is a lot of acti-
vity in the kitchen.
Setting option of level 3: between 0 and 100 %.
Factory setting of level 3: 75 %.
Level 4 is used mainly in summer to lower the indoor
temperature. Remember that a higher air exchange rate
increases the energy consumption.
Setting option of level 4: cannot be configured.
Factory setting: 100 %.

achieved as the supply air on level 1.
