5.4.7 Fan compensation
– Disable comp parameter setting (Main Index > Unit > Fan control > Disable
comp) must be observed for each compensation.
– All types of compensation that results in a step-up or switch, are added to the
overall compensation ∑ comp.
– All types of compensation that result in a step-down or switch, are subtracted
from the overall compensation ∑ comp.
– ∑ comp up and ∑ comp down are limited to 100 %.

– Fan cooling [%]
– Fan compensation [%] (Increase)
• From fan control:
– Summer compensation [%] (if positive).
– Winter compensation [%] (if positive).
• From humidification:
– Fan compensation [%] (Increase)
• From air quality control:
– Function normal [%]
• From temperature control:
– Fan Heating [%]
– Fan compensation [%] (Decrease)
