TIP
See page 36 for a more in-depth introduction
to the heat pump's control system (operation,
menus etc.).
If the building is cooled when F1255PC BE starts, the
compressor may not be able to meet the entire demand
without having to use additional heating.
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 start-up is carried out cor-
rectly and cannot be bypassed. The start guide can be
started later in menu 5.7.
Caution
As long as the start guide is active, no function
in the installation will start automatically.
The guide will appear at each installation restart
until it is deselected on the last page.
