Commissioning
The first time the heat pump 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 heat pump’s basic settings.
The start guide ensures that the start-up is carried out
correctly and cannot be bypassed. The start guide can
be started later in menu 5.7.
This applies to a heat pump with approximately 4 kW
rated output.
For a 15 kW heat pump the corresponding flow is from
0.09 l/s (324 l/h) to 0.14 l/s (504 l/h).
Caution
As long as the start guide is active, no function
in the installation will start automatically.
The guide will appear at each installation re-
start until it is deselected on the last page.
