ECA 100 ipro RCH

• Small room fans for extracting air from rooms.
• Model similar to the ECA 100 ipro RC.
• Additionally with fully automatic humidity control.

Fully automatic humidity control function

Normally, the fan runs in standard operation at a power level that is manually set or predefined through an RLS RC.

When starting up the RCH fan, this fan is set in line with the current relative room humidity. This humidity is saved as the first reference value. No further manual setting of a reference value is necessary.

If the relative humidity drops directly following the installation, this is saved as the new reference value. The lowest possible reference value is 48 % relative humidity. If the room humidity increases by 7%, the fan switches on automatically at power level 1 (78 m³/h).

• If the room humidity increases even further, the unit switches to power level 2 (92 m³/h).
• If there are no further increases, the unit continues to run at power level 1 (78 m³/h) until the humidity again falls below the saved reference value.

If humidity falls below the reference value, the power level is also switched back:

• If an RLS RC is deployed, operation is done in line with the setting on the RLS RC.
• In the case of operation without an RLS RC (individual unit), the fan switches back to the last power level that was active before humidity operating mode.

The currently prevailing room humidity is saved as the new reference value.

A new reference value is also saved if the radio switch is operated during humidity operating mode.
