Installation instructions for professionals
Settings that are not defined
in the settings wizard
The ventilation units are pre-prepared at the factory
in order to shorten the installation time. However,
the possible extras cannot be taken into account for
installation. The settings for the devices connected to the
motherboard must be configured on the control panel.
The following table contains the MD card connections
and their placements on the motherboard.
MD card connections
NTC sensors
The MD card has connections for eight (8) NTC-10 sensors.
