•
ECA 150 ipro KH
with electrically operated in-
ternal shutter.
• Barrier-free product as the fan switches itself on
and off via the humidity sensor.
• Switch-on humidity does not have to be set.
Fan monitors the room humidity.
• 2 performance levels as a standard feature.
Fan extracts air automatically in level 1 or level
2, depending on the room humidity.

ally also be switched via separate switch.
.
Automatic humidity function
Once the fan is installed, it adjusts to the room
humidity prevailing at that time (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 ref-
erence value is saved. The lowest possible refer-
ence value is 48 % relative humidity.
When the room humidity increases
• If the room humidity increases by 7%, the fan
switches on automatically at power level 1 (200
m³/h).
• If the humidity increases even further, the unit
switches to power level 2 (250 m³/h).
• If there are no further increases, the fan contin-
ues to run at power level 1 (200 m³/h) until the
humidity again falls below the saved reference
value.
When falling below the reference value
•
H and KH:
Overrun operation starts with the set
overrun time. The current reference value is
then saved.
•
RCH and KRCH:
No overrun operation.
Value does not fall below reference value for 1
hour
•
H and KH:
Overrun operation starts. Fan then
switches off.
•
RCH and KRCH:
Fan switches off.
Operation using light and/or radio switch
•
H and KH units
can also be operated using the
light switch. With “Light on”, the set operating
programme starts with the start delay →
The operating program
takes priority over the automatic humidity func-
tion. After switching off, the 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.
• Optionally,
RCH/KRCH units
can be operated
in 2 levels using a radio switch. Switching
through the DS RC or window contact is pos-
sible during humidity operating mode.
