7 Technical data
Control with motion detector. Full load level after motion
is detected (range motion sensor is 5 m)
Barrier-free product, as it switches itself on and off auto-
matically
Not speed controllable
Electrical plug connection for quick connection of the ER
EC with ER GH housing and ER-AK, ER-AH or ER-AB
with the ER EC fan insert.
Air volume – base load 30 m³/h for continuous operation
Air volume of the base load and full load levels can be set
Additional air volumes that can be set
in base load: 20 m³/h, 40 m³/h, 60 m³/h or 100 m³/h and
in full load: 20 m³/h, 30 m³/h, 40 m³/h or 100 m³/h
Full load level on/off via light switch or separate switch.
During manual operation (e.g. using light switch), the
start delay and overrun time apply.
Full load operation (60 m³/h) with start delay of 60
seconds and overrun time of 15 minutes, non-adjustable
Full load operation (60 m³/h), start delay can be set with
0, 30, 60*, 90 or 120 seconds
Overrun time of the full load level can be set for 0, 3, 6,
15*, 24 or 30 minutes
Adjustable interval control for ventilating rooms that are
not regularly used. Time interval can be set for 0*, 1, 2, 4,
6 or 12 hours, 10 min. operating time per interval
Interval control can be switched off.
Switching option: The base load can be switched on or
off by an additional switch (Wiring diagrams).
* Factory setting: Tolerance of time details max. ±
5 %
** For the ER-AB, the start delay only affects the
light switch operation.
*** For ER-AH humidity control in full load 40 m³/
h, 60 m³/h and 100 m³/h can be set.
7 Technical data
7.1 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 EC units have resistance to interference in
line with EN 55014-2 (depending on pulse type
and an energy factor of 1000 to 4000 V). These
values can be exceeded when operating with
fluorescent tubes. In this case, additional inter-
ference suppression measures (L, C or RC
modules, protection diodes, varistors) are re-
quired.
7.2 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;
ER-AH
ER-AB
