5 Technical data
5.1 Environmental conditions and op-
erating limits
• Permissible maximum temperature of air me-
dium + 40 °C.
• The air supply to the home must be set up so
that virtually no air can flow into the living areas
from the kitchen, bathroom or WC.
• A room from which the air is to be extracted
must be fitted with a non-closable, free supply
air cross section of at least 150 cm², e.g. with
Maico MLK door ventilation grille.
• ER-UP/Centro units have resistance to interfer-
ence in line with EN 55014-2 (depending on
pulse type and an energy component of 1000 to
4000 V). These values can be exceeded when
operating with fluorescent tubes. In this case,
additional interference suppression measures
(L, C or RC modules, protection diodes, varis-
tors) are required.
• Take the risk of draughts into account when
planning by selecting a suitable installation loc-
ation.
5.2 Regulations for operation with
fireplaces
Sufficient supply air intake
must be ensured
during operation with
air-ventilated fireplaces
.
The maximum permitted pressure difference per
residential unit is 4 Pa.
The unit may only be installed in residential units
with air-ventilated fireplaces under the following
conditions:
• the evaluation criteria drawn up by the respons-
ible, regional master chimney sweep are met;
• Parallel operation of air-ventilated fireplaces for
liquid or gaseous fuels and air-extracting equip-
ment can be prevented using safety devices or
• the extraction of exhaust gas from the air-ventil-
ated fireplaces is monitored by special safety
devices. The ventilation system or the fire-
places must be switched off if the equipment is
triggered.
