Product description
● EC A piano STANDARD, speed
controllable. On/off with light switch or
separate switch (both to be supplied by the
customer). Fan switches on/off immediately
when the switch is operated.
● ECA piano TC with adjustabl e overrun
time, not speed controllable. On/off wi th
light switch or separate switch (both to be
supplied by the customer). Fan switches off
immediately when t he overrun time expir es
after the s witch has been operated.
Overrun time: appr ox. 3 … 25 min,
– factory s etting: approx. 6 min.
● ECA piano H, with humidity control and
adjustable overrun time, not speed
controllable. Different functions depending
on the connection version.
Version 1: The fan sw itches on
automatically when the relati ve ambient
humidity in the area of the fan exce eds the
pre-defined s witching point. The fan is
switched off when the humidity level drops
below the swit ching point threshold and
once the define d overrun time has expired.
The fan can also be d eactivated wi th the
optional “S1” switch.
Version 2: The fan is switched on
automatically, controll ed by the humidity
level (as version 1) or manuall y by the light
switch. If the relative humidity level remains
above the switching point threshold, the fan
cannot be switched off, even with the light
switch. The f an switches off when the
humidity level dr ops below the switching
point threshold and once the defined
overrun time has expired.
Valid for both versions:
1. Ambient humidity:
approx. 50 … 90 % relative humidity
Factory setting:
approx. 70% relative humidity
2. Overrun time: approx. 0.5 … 18 min,
Factory setting: approx. 12 min

5. Environmental conditions and
operational limits
● Ma ximum per mitted airst ream temperature:
+40 °C
● I f the fans are bei ng used with air-
ventilated fi replaces, you must ensure
that there is sufficient flow of supply air.
The maximum permitted pressure
difference per domestic unit is 4 Pa.
● Res istance to interference complies with
EN 55014-2, depending on the pulse shape
and energy fact or 1000 to 4000 V
If operating wi th fluorescent tube lighting,
additional interferenc e suppression
measures (L, C components or RC
modules, protection diodes, varistors) are
needed, as these values can be exceeded.

7. Installation preparation
Wall
Maintain the minimum spacings according
to the picture.
Make sure there is a flat surface to mount
the housing on.
Prepare the wall br eakthrough.
Minimum diameter is 105 mm.
Use a ZM11 mounting plate, with
rectangular wall breakthroughs.
Lay the cables.
CAUTION
If the surface is uneven, there
is a danger of short circuits
and damage to the device if
water can penetr ate the
housing!
Make sure there i s a flat
surface i n the area of the
sealing ring [5].
If necessary, provide
additional sealing measures.
Ceiling
CAUTION
Damage to unit caused by
short circuit through build-up
of condensation in the fan
housing.
Make sure thermal insulation
of ventilation ducts is installed
correctly.
Prepare for assembly as descri bed above
(see wall) .
Prepare cover [4] .
Remove cover from housing before drilling.
Drill through cover using an app ropriate
drill bit, in order to prevent damp and the
build up of germs in the fan housing.
Duct
Deburr the insi de edges of the duct.
Housing [1]
Check that the sealing ring [5] is present at
the rear of the housing and that i t is seated
correctly.
