TIP
See the section "Control – Introduction" for a

Commissioning
The first time the installation is started a start guide is
started. The start guide instructions state what needs
to carried out at the first start together with a run
through of the installation’s basic settings.
The start guide ensures that start-up is carried out cor-
rectly and cannot be bypassed. The start guide can be
started later in menu 5.7.
Under the start guide, the reversing valve is run back
and forth to help vent VVM 225.
Caution
As long as the start guide is active, no function
in VVM 225 will start automatically.
The start guide will appear at each restart of
VVM 225, until it is deselected on the last page.
