Week-clock control
4.1
Week programme programming
The week programme can be used to set the desired fan speed (base fan
speed) and supply air temperature for each hour of the day on seven days
a week. The week programme overrides manual adjustments.
Carbon dioxide and humidity adjustment can increase fan speed but never
decrease it below the base fan speed set in the week programme.
Example: Monday
It is the intention to decrease fan speed to speed 2 and supply air tempera-
ture to 17 ºC between 07:00 (7 a.m.) and 16:00 (4 p.m.). After that, fan
speed is raised to speed 4 and supply air temperature to 20 ºC. For the
evening, fan speed is boosted to speed 6 between 19:00 and 21:00 (7
p.m. and 9 p.m.), after which fan speed is lowered back to 4.

The maximum fan speed setting can
be selected to be active either only in
connection with (carbon dioxide and
humidity) sensor adjustments or perma-
nently. The selection is done with the +
and – buttons.

Adjusting fan on the supply air side
DC fan, supply
100%
The desired adjustment value for the
supply air fan is selected with the +
and – buttons. The rotation speed of
the supply air fan can be decreased
by decreasing the percentage.
OPERATING INSTRUCTIONS FOR CONTROL PANEL
Move the cursor with the arrow keys and
change values with the + and – buttons.
Note that to exit and save when the
programming is fi nished, move the cursor
below the word Exit and press + or –.
Changes in fan speed (Sp.) and supply
air temperature (Temp.) are only made for
the hours desired; in other cases, use N
(no change to previous).

°C (Temp =17).
Move the cursor to the following hour.
Monday (D=1), 16:00 (H=16),
fan
speed 4 (Sp. = 4), supply air temperature
20 °C (Temp =20).
Move the cursor to the following hour.
Monday (D=1), 19:00 (H=19),
fan
speed 6 (Sp.=6), supply air temperature
no change (Temp=N).
Move the cursor to the following hour.
Monday (D=1), 21:00 (H=21),
fan
speed 4 (Sp.=4), supply air temperature
no change (Temp=N).
Move the cursor to the following hour.

Adjusting fan on the extract air side
DC fan, exhaust
100%
The desired adjustment value for the
extract air fan is selected with the +
and – buttons.
The rotation speed of the extract air fan
can be decreased by decreasing the
percentage.

Fan speed level adjustment
Speed 1 level
15%
The desired fan speed level is adjusted
from the menu. Adjustment range is
0–100%. However, fan speeds limit
the adjustment range as follows:
If for instance speed 3 is 30%, speed 2 cannot be increased to more
than 29% and speed 4 cannot be decreased below 31%.
The fan stops when the setpoint is 14% or lower. The adjustment is made
with the + and – buttons. There are 8 displays, one for each fan step.
