• Overrun time can be adjusted from 3 to 25
minutes (factory setting 6 minutes).
• On/off with light switch or separate switch.
• Not speed-controllable.
• Required mains cable 5 x 1.5 mm².
5.3 ECA piano H
• Small room fans for extracting air from rooms.
• Model with humidity control (automatic humidity
function) and adjustable overrun time.
•
ECA piano H
with fixed internal grille.
• Barrier-free product as the fan switches itself on
and off automatically.
• Switch-on humidity can be adjusted from 50 %
r.h. to 90 % r.h. (factory setting 70% r.h.).
• With an additional switch, it is possible to switch
manually. The fan then runs on for the set over-
run time.
• Overrun time can be adjusted from 0.5 to 18
minutes (factory setting 12 minutes).
• Not speed-controllable.
• Required mains cable 3 x 1.5 mm². When using
an optional switch, provide a 5 x 1.5 mm² mains
cable.
• Automatic humidity function with priority.
•
Humidity function depending on connection
variant 1 or 2.
•
Connection variant 1
Fan switches on automatically when the relat-
ive room humidity in the area of the fan ex-
ceeds the preset switching point. Switching
off takes place after the humidity has fallen
below the switching point and the set overrun
time has elapsed. With additional switch
“S1”,the fan can be switched off manually.
•
Connection variant 2
Fan is turned on via the automatic humidity
function, as in connection variant 1, or manu-
ally (light switch).
Note:
With a relative room
humidity over the switching point, the fan can
no longer be switched off, not even with the
light switch.
The fan switches off when the room humidity
in the area of the fan is under the switching
point and the overrun time has elapsed.
6 Technical data
6.1 Ambient conditions
• Permissible maximum temperature of air me-
dium + 40 °C.
• Resistance to interference according to EN
55014-2 depending on pulse shape and energy
component 1000 to 4000 V. If operating with
fluorescent tubes, extra interference suppres-
sion measures are needed (L or C components
or RC modules, protection diodes, varistors) be-
cause these values may be exceeded.
• Recommendation: When operating on switches
with a glow lamp, wire an X2 capacitor (220
nF/250 V) to zero. The capacitor is to be
provided by the customer.
• Storage: Store unit exclusively in a dry location
(-20 to +50 °C).

7 Preparation for installation
7.1 Wall
Use mounting material suitable for base and of
sufficient dimensions. Ensure sufficient supply air.
The prescribed minimum distances to the
wall and the ceiling shown in the figure must
be observed.
1. Make sure the housing has a level base.
2. Fit wall breakthrough or drill core hole. Min-
imum diameter, 105 mm.
ð
Recommendation: Fit WH 100 wall sleeve.
Fit wall breakthrough with minimum dia-
meter 115 mm.
