2.
Follow the instructions in the display's start guide.
If the start guide does not start when you start the
F1355, start it manually in menu 5.7.
TIP
Refer to the operating manual for a more in-
depth introduction to the control system in
F1355 (operation, menus, etc.).
If the building is cooled when F1355 starts, the com-
pressor 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.
