Air extraction
This positioning of the switch enables extract operation of the ventilator in
Ventilation mode. In heat recovery mode, the fan starts operating first in extract
mode.
To prevent pressure imbalances in a room, the sequence for the KERS in series can be for example the following:
first KERS = switch to the right; second KERS = switch left; third KERS = switch to the right; fourth KERS = switch left,
and so on.
Switch 3/4/5: Humidity based control
The unit can also work to keep humidity below a certain preset level. This mode is especially useful in all those
rooms where there is no permanent occupation but that may have mold problems due to excessive moisture. In
this case you will get a ventilation focused on solving or preventing the problem with the least electricity
consumption.
To enable this mode, you must use the dip switch 3/4/5 by setting the humidity threshold. The unit continuously
measures the humidity of the air extracted from the environment and if it exceeds the set humidity value, it will
activate the maximum speed. When the room humidity has dropped below the set value, the device will return
to the previously set speed. Before returning to the preset speed, a delay can be set with the dip switch 6 and 7.
