 the Preheater element is switched on soonest; this level offers the best guarantee of balanced 

ventilation. Vice versa, in 

economy

 the Preheater element switches on at the last possible moment; balanced ventilation is 

not guaranteed in this mode.

When commissioning the ComfoAir, the Preheater programme can usually be left at level 2: 

nominal

 

mode

 (factory setting). In 

areas with frequent cold spells in winter (frequent periods of -10°C or lower), level 1 should be selected: 

high

 

protection

 or even 

level 0:
