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.

humidity) sensor adjustments or perma-

nently. The selection is done with the + 

and – buttons.

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).

Monday (D=1), 07:00 (H=7),

  fan speed 

2 (Sp. = 2), supply air temperature 17 

°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).

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.
