ECA piano H, with humidity control and
adjustable overrun time
, not speed
controllable. Different functions depending
on the connection version.
1
Version 1:
The fan switches on
automatically when the relative ambient
humidity in the area of the fan exceeds the
pre-defined switching point. The fan is
switched off when the humidity level drops
below the switching point threshold and
once the defined overrun time has expired.
The fan can also be deactivated with the
optional “S1” switch.
Version 2:
The fan is switched on
automatically, controlled by the humidity
level (as version 1) or manually 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 fan switches off when the
humidity level drops 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.

Resistance to interference complies with
DIN EN 55014-2, depending on the pulse
shape and energy factor 1000 to 4000 V
If operating with
fluorescent tube lighting
,
additional interference suppression
measures (L, C components or RC
modules, protection diodes, varistors) are
needed, as these values can be exceeded.
