9.1 Adjustment with CI60
9.1.1 Adjustment
Only stage 2 (NORMAL) needs to be adjusted.
Stages 1
and 3 have fixed settings, while stage 2 has to be adjusted as
required in the individual home.
The function of the different stages:
MIN
Must not be used when the home is in use.
Must not be used in the first two heating
seasons.
NORMAL
Used under normal conditions. On this
setting the air supply must be adjusted
according to current regulations.
MAX
Used if there is a need for increased air
supply on account of higher occupancy or
a raised humidity level, for example during
showering or when clothes are being dried.
This setting is normally used for limited
periods.
The ventilation unit's air supply is adjusted in speed level
NORMAL using the knobs on the back of the cover. Knob 9 is
used for supply air level and knob 8 for extract air level (see
Fig. 26). The adjustment range is 20-100% of the maximum
level according to the scale on the knob.
Factory settings for supply air/extract air:
MIN
50% (fixed)
NORMAL
75% (variable)
MAX
100% (fixed)
9.1.2. Adjusting the temperature
The temperature required for the supply air can be set
with knob 11. The adjustment range is 10 - 30°C. It should
normally be set to around 18°C. Use of the factory setting is
recommended.
If necessary, the ventilation unit's additional heating can
also be switched ON/OFF with switch 10. In this case only
the rotating heat exchanger is used as a source of heat. It is
best to leave it in ON position, as the unit will then respond
automatically when there is a need for additional heating.
