Overall ventilation functions
Introduction
The units can ventilate your home in three different operation modes. The modes are
selectable according personal needs, taking in mind that national rules and regulations,
can state a minimum ventilation requirement.
Never turn off the main power to shut down the ventilation. This could ultimately result
in condensate water dripping from air inlets.
Manual
ventilation level
In manual operation, the unit will permanently operate with the selected fan speed. The
mode can be selected on the keypad or through the LAN interface
Automatic con-
trolled by time
In time controlled operation mode, the unit automatically adjust the fan speed, accord-
ing to a fixed time table over a week, in order to cover the varying needs for fresh air,
during day and week. One of the 11 time schedules, can be edited in the software ser-
vice tool and through the LAN interface
The Auto mode can be engaged on the control panel or through the LAN interface.
Controlled by VOC
and RH% sensor
(accessory)
In this mode (Demand) the unit will automatically adjust the ventilation level, to comply
with the ventilation needs, measured in the outgoing air by the VOC and RH% sensors.
This operation mode is only possible if the unit is fitted with the air quality sensor kit
