START GUIDE
NOTE
There must be water in the climate system
before S1255 is started.
NOTE
With several heat pumps connected, the start
guide must first be run in the subordinate heat
pumps.
In the heat pumps that are not the main unit,
you can only make settings for each heat
pump’s circulation pumps. Other settings are
made and controlled by the main unit.
1. Start S1255 by pressing the on/off button once
(SF1).
2. Follow the instructions in the display’s start guide.
If the start guide does not start when you start the
S1255, 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.).
If the building is cooled when S1255 starts, the com-
pressor may not be able to meet the entire demand
without having to use additional heating.
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 the start-up is carried out
correctly and, for this reason, cannot be skipped.
Caution
As long as the start guide is active, no function
in the installation will start automatically.
The start guide will appear at each restart of
the installation, until it is deselected on the last
page.
