Information is provided on the display about the heat
pump's operating status. A screen saver is normally
shown on the display screen. The plus and minus but-
tons and the enter button can be used to scroll through
the menu system as well as to change the set value in
some menus.
The plus button is used to move forward to
the next menu on the current menu level
and to increase the value of the parameter
in menus where this is possible.
The minus button is used to move back to
the previous menu on the current menu
level and to decrease value of the param-
eter in menus where this is possible.
The enter button is used to select sub-
menus of the current menu, to permit
parameters to be changed and confirm any
changes to parameters. When the menu
number ends with "0" this indicates there is
a sub-menu.
