Start-up and inspection
START GUIDE
NOTE
There must be water in the climate system before
VVM S320 is started.
1. Start VVM S320 by pressing the on/off button (SF1).
2. Follow the instructions in the display’s start guide. If the
start guide does not start when you start the VVM S320,
you can start it manually in menu 7.7.
TIP
See the section "Control – Introduction" for a more
detailed introduction to the installation's control
system (operation, menus, etc.).
Commissioning
The first time the installation is started a start guide is star-
ted. The start guide instructions state what needs to carried
out at the first start together with a run through of the in-
stallation’s basic settings.
The start guide ensures that the start-up is carried out cor-
rectly and, for this reason, cannot be skipped.
Caution
As long as the start guide is active, no function in
VVM S320 will start automatically.
