Meaning
Note: In GUARANTEED PROTECTION MODE the frost-free element is switched on soonest; this level offers the best guarantee of balanced ventilation. Vice versa, in ECONOMY MODE the frost-free element switches on at the last possible moment; balanced ventilation is not guaranteed in this mode. When commissioning the ComfoAir, the frost-free programme can usually be left at level 2: NOMINAL MODE (factory setting). In areas with frequent cold spells in winter (fre- quent periods of -10°C or lower), level 1 should be selected: HIGH PROTECTION or even level 0: GUARANTEED PROTECTION
