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.
