2.3 Explanation of the SERVICE MODE menu
To enable maintenance of the unit, it is fitted with a
SERVICE MODE. By activating this mode, the basic
functions of the unit are deactivated and the bypass
valves of the heat exchanger are removed. To prevent
electrically charged parts being touched, the power
must still be manually disconnected from the unit
after setting the SERVICE MODE. Once the power
is reconnected to the unit, the SERVICE MODE will
be deactivated automatically. Also the service menu
password will have to be re-entered.
