COMMISSIONING
The first time the installation is started, a start guide is

you want in the display.

in GV-HR 120 will start automatically.
OPERATION IN THE START GUIDE

After the language has been chosen, GV-HR 120 will
enter the appropriate program version in the selected
language, which takes approx. 1.5 minutes.
SD CARD
After commissioning GV-HR 120, it is possible to have
the installation in operation without an SD card (AA32),
but there will then not be any help texts in the display.
SETTING THE VENTILATION
The ventilation must be set according to applicable
standards. Adjust the supply air flow to guarantee a
negative pressure.
The settings are adjusted in Service menu, menu 10-15.
Even if ventilation is roughly set at installation it is im-
portant that a ventilation adjustment is ordered and
permitted.
Caution
An incorrectly set ventilation flow can damage
the house and may also increase energy con-
sumption.
NOTE
Order a ventilation adjustment to complete the
setting.
