Exhaust Air Elements; Product Features; Technical Data; Environmental Conditions And Oper- Ating Limits - Maico Centro-M Installation And Operating Instructions Manual

6 Technical data

• with a fireproof installation shaft for ER-UPB
housings;
• if unit is completely installed;
• with permissible air filters (Permitted exhaust air
systems);
• with the outside air openings stated in the plan-
ning documents;
• Centro-E/Centro-H: pressure controller for the
centralised fan required.

5.5 Exhaust air elements

Centro-M
Manual model. For use in systems with jointly
variable volumetric flows. Fixed air volume setting
by pushing out sealing plugs in each exhaust air
element.
Centro-E
Electric model. With electro-thermal servomotor
for switching between basic and demand-based
ventilation. Fixed air volume setting of the basic
ventilation by pushing out sealing plugs in each
exhaust air element. Demand-based ventilation
automatically via servomotor.
Centro-H
Model with automatic humidity control. Barrier-
free product as the fan switches itself on and off
automatically. With fixed air volume setting of the
basic ventilation by pushing out sealing plugs in
each exhaust air element. Demand-based ventila-
tion automatically or via a switch (for example
light switch).

5.6 Product features

• Fire protection identical with Maico ER single-
room air extraction, see ER UP/Centro main in-
structions.
• No cold smoke barriers required.
• No additional telephony sound absorbers re-
quired.
• It is possible to rotate the cover by ± 5° (for
housings which have been fitted at an angle).
• Control circuit board in spiral housing for
Centro-H.
• Centro-H not approved for second room con-
nection.
• The flush-mounted housing has easy to install
snap-in exhaust air elements.
• Quick installation of E and H units thanks to
electrical plug connection in flush-mounted
housing.

• Shaft level difference according to DIN 4109,
tested by IAB Oberursel (The Institute for
Acoustics and Building Physics in Germany).
• Cover with exhaust air filter and time strip. Air
filters are to be changed regularly when filter
change is indicated (time strip).
• Trouble-free filter change without tools.
• Centro-M with protection class II. Installation
also permissible with water jets (DIN VDE
0100-701, area 1).
The time strip is visibly attached to a location
of your choice (e.g. next to the cover) and after
the filter change interval has elapsed, it can be
disposed of in the domestic waste. Do not affix
the time strip under the cover. New time strips are
included in the scope of delivery of the exchange
air filter.

6.1 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.
• Minimum volumetric flow per exhaust air ele-
ment 30 m³/h.
• 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
MLK door ventilation grille.
• Centro-E and Centro-H with resistance to inter-
ference according to EN 55014-2 – 1000 to
4000 V depending on pulse type and energy
component. When operating with fluorescent
tubes, these values can be exceeded. In this
case, additional interference suppression meas-
ures (L, C or RC modules, protection diodes,
varistors) are required.
6.2 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:
