ECA 150 ipro H, ECA 150 ipro KH

• Small room fans for extracting air from rooms.
• Model with humidity control (fully automatic), start delay and overrun time.
• ECA 150 ipro H with fixed internal grille.
• ECA 150 ipro KH with electrically operated internal 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.
• Operation possible without switch. Can optionally also be switched via separate switch.
• Further product features → Unit versions.

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 reference value is saved. The lowest possible reference 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 continues 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 → Operating programs The operating program takes priority over the automatic humidity function. 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 possible during humidity operating mode.
