3. Environmental conditions and
operating limits
● Permissible maximum temperature of air
medium + 40 °C.
● The domestic air supply must be set up so
that virtually no air can flow into the living
areas from the kitchen, bathroom and WC.
● A room from which the air has to be ex-
tracted must be fitted with a non-closable,
free supply air cross section of at least
150 cm², e.g. with Maico door ventilation
grille MLK.
● Sufficient supply air intake must be en-
sured during operation with air-ventilated
fireplaces. The maximum permitted
pressure difference per living unit is 4 Pa.
● VZ, F, KVZ and KF units: Resistance to
interference according to EN 55014-2
depending on pulse shape and energy
component 1000 to 4000 V. If operating
with fluorescent tubes, extra interference
suppression measures are needed (L or
C components or RC modules, protection
diodes, varistors) because these values
may be exceeded.
