The menu is not shown in full here.
NOTE
If 2 heat pumps are connected, note the number displayed in
the top menu row. It provides information about which heat
pump is currently addressed.
In order to change the addressed heat pump: page 11,

Program area “Service“
NOTE
The software automatically detects the connected heat
pump type. Parameters that are not relevant for the con-
ditions of the system and/or the heat pump type are hid-
den. Some of the parameters documented in this program
area may therefore not appear on the screen of your heat-
ing and heat pump controller.
Many menus require scrolling with the “rotary pushbut-
ton”.
NOTE
Some menu entries and parameters are also only visible or
adjustable when installation technician or customer ser-
vice access is active. The dierent data access levels are
marked in this operating manual by symbols.
page 2, “Symbols“
NOTE
Some parameters have adjustable value ranges. These can
be found in the appendix.
