Risk to health if filters are not
replaced or if there are no air filters.
Heavily soiled or moist air filters can
accumulate harmful substances (mould,
germs, etc.). This can also occur during a
prolonged shutdown of the fan. If the air
filter is missing, the fan and air channels
become soiled. Never operate the fan
without air filters. Only use original filters.
Regularly change air filter when a filter
change is indicated (LED or TimeStrip). If the
fan has not been used for a long time, always
replace the air filters.
Risk of injury when working at
heights. Use appropriate climbing aids
(ladders). Stability should be ensured, if
necessary have the ladders steadied by a
2nd person. Ensure that you are standing
securely and cannot lose your balance and
that there is no one under the unit.
Exercise caution when handling
packaging materials. Observe
applicable safety and accident prevention
requirements. Store packaging material out of
the reach of children (risk of suffocation).
Risks from parts which may affect
the ventilation system which are
added or modified at a later date. Parts
(range hood, air-ventilated fireplace etc.)
which are added or modified at a later date
may result in health risks and operation which
is not permitted. Parts may only be added or
modified at a later date if system compatibility
is established/ensured by a planning office. If
using an exhaust air range hood or airventilated fireplace, this must be accepted by
a regional master chimney sweep.
Danger from operating with the fan
not fully mounted. Electric
components are a potential source of
electric shock. If the unit is open, all off the
supply circuits must be switched off (mains
fuse off), secured against being accidentally
switched back on and a visible warning sign
positioned. Only operate the fan when it is
completely installed.
Risk of injury and health risk in the
event of changes or modifications or
if components which are not permitted are
used. The unit may only be operated with
original components. Changes and
modifications to the units are not permitted
and release the manufacturer from any
guarantee obligations and liability, e.g. if the
housing is drilled at a point which is not
permitted.
Danger if the relevant regulations for
electrical installations are not
observed.
● Before removing the housing cover or
removing the fan insert and before
installing the electrics, switch off all supply
circuits, switch off mains fuse, and secure
them against being accidentally switched
back on again. Attach a warning sign in a
clearly visible place.
● Be sure to observe the relevant regulations for electrical installation; e.g. DIN EN
50110-1. In Germany, particularly observe
VDE 0100, with the corresponding
sections.
● Unit may also be energized even when at
a standstill and may be switched on
automatically by sensors (time delay,
humidity etc.) or by the thermal switch in
the motor winding. Maintenance and fault
finding only permissible when carried out
by trained electricians.
● The degree of protection stated on the
rating plate is only guaranteed if
installation is undertaken correctly and if
the connecting cable is correctly guided
through the stepped grommet (The
grommet must completely enclose the
cable sheathing). The fan insert must also
be engaged and the housing cover
installed.

Permitted maximum air temperature + 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 or WC.
A room from which the air has to be extracted
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.
ER EC units have resistance to interference
in line with EN 55014-2 (depending on pulse
shape and an energy factor of 1000 to 4000
V). These values can be exceeded when
operating with fluorescent tubes. In this case,
additional interference suppression measures
(L, C components or RC module, protection
diodes, varistors) are required.
7.1 Regulations for operation with
fireplaces
For operation with air-ventilated fireplaces,
sufficient supply air intake must be
ensured. The maximum permitted pressure
difference per residential unit is 4 Pa.
The fan may only be installed in residential
units with air-ventilated fireplaces if:
● the evaluation criteria drawn up by the
responsible, regional master chimney
sweep are met;
● a parallel operation of air-ventilated
fireplaces for liquid or gaseous fuels and
the air-extracting equipment can be
prevented, or
● the extraction of exhaust gas from the airventilated fireplaces is monitored by
special safety equipment. The ventilation
system or the fireplaces must be switched
off if the equipment is triggered.

● Settings menu is automatically exited after
60 seconds without pushing buttons.
12.3 Automatic humidity function
ER-AH
the humidity in permanent base load
operation. If the unit is operated
without permanent base load operation, the fan starts every 2 minutes
for 30 seconds with reduced speed
(base load 20 m³/h) and measures
the automatic humidity function
Once the ER EC unit is installed, it adjusts to
the currently prevailing room humidity
(relative humidity). This humidity value is
saved as the first reference value. The
reference value does not have to be specified
manually.
If the relative humidity falls below the
reference value during operation, the newly
established reference value is saved. The
lowest possible reference value is 45 %
relative humidity.
If the room humidity rises quickly, the ER
EC unit (depending on the humidity) turns up
continuously to match the humidity. The
maximum flow rate at 100 % r. h. is 60 m³/h
or 100 m³/h, depending on the setting of V2.
If the humidity falls below the reference
value, overrun operation mode starts with the
set overrun time. Then, the current reference
value is saved.
If the humidity does not fall below the
reference value within 60 minutes, the
ER EC unit switches to the set overrun mode
and then switches off.
In case of “Light on” the ER EC unit starts
up. If the light is switched off, the ER EC unit
continues to run until the remaining overrun
time has passed. The automatic humidity
function is then assigned maximum priority
again and controls the unit as described
above.
Notes
● ER EC units can also be operated using
a light switch during operation with
automatic humidity function.
● The interval operation is deactivated
during the humidity operating mode.
● Overrun time:
● A set overrun time of 0 minutes is only
valid for manual function with a light
switch.
● For operation with automatic humidity
function, the minimum overrun time is
3 minutes.
● For settings > 0 minutes, the overrun
time is the same for manual (light switch)
and humidity operating modes.
● Volumetric flows that can be set
V1: 20, 30, 40 m³/h
V2: 60, 100 m³/h

12.4 Motion detector function
ER AB
If a movement is detected/recognised, the
ER EC unit switches to full load level
automatically without a start delay.
If no movement is registered, the overrun
delay starts. Then, the ER EC unit switches
off.
Cleaning/maintenance
The unit is practically maintenance-free. Only
the air filter needs replacing every 6 months
at the latest, depending on the degree of
soiling.
The unit will be damaged if incorrect
cleaning agent is used. Do not use
aggressive cleaning agents.
