22USING THE UNIT FOUR VENTILATION UNIT PROFILESAt homeUse this ventilation profile when the dwelling or the premisesare occupied.AwayUse this ventilation profile when the dwelling or premises areunoccupied, e.g. during a trip or other long absence.Fireplace profileUse this ventilation profile when, for example, you are makinga fire in the fireplace. This profile is primarily used to createmomentary overpressure in the apartment.BoostUse this profile to increase the ventilation rate, e.g. when thereare more people than usual in the dwelling or elsewhere on thepremises.Symbols for ventilation profilesThe following symbols are used on the main displays of the profiles:Table 2. Profile symbolsSYMBOL DESCRIPTIONThe profile in use is either the At home, Away, or Boost profile. The week clock is turned off.The profile in use is either the At home, Away, or Boost profile. The week clock is on.The Fireplace profile is used. The week clock might be turned on.These symbols indicate the currently active profile. The smallest fan icon indicates that the Awayprofile is in use, and the largest fan icon indicates that the Boost profile is being used.Droplet symbols indicate the relative humidity of air. The symbols are:• One drop — The humidity sensor has been successfully installed and the relative humidity ofair is normal.• Two drops — The relative humidity of air is slightly higher than normal. The fan speed will beautomatically increased if automatic adjustment is allowed.• Three drops — The relative humidity of air is significantly higher than normal. The fan speedwill be automatically increased if automatic adjustment is allowed.These symbols indicate the carbon dioxide level in the air. The colour codes are:• Green — The carbon dioxide sensor has been installed and the carbon dioxide level isnormal.• Orange — The carbon dioxide level is slightly higher than normal. The fan speed will beautomatically increased if automatic adjustment is allowed.• Red — The carbon dioxide level is significantly higher than normal. The fan speed will beautomatically increased if automatic adjustment is allowed.IMPORTANTProlonged overpressurecan result in damage to thestructures of the building.USING THE UNITTIPUsing the At home, Away, andBoost profiles according toneed helps to save energy.VENTILATION PROFILES
