General

Accessing coding level 1
Note: Codes are displayed as plain text.
Codes that have no function due to the heating
system equipment level or the setting of other
codes are not displayed.
Heating systems with one heating circuit without
mixing valve and one or two heating circuits with
mixing valve:
The heating circuit without a mixing valve is
designated "Heating circuit 1" and the heating
circuits with mixing valve as "Heating circuit 2"
or "Heating circuit 3".
If the heating circuits were given individual designations,
the selected designation and "HC1", "HC2" or "HC3"
appear instead:
Select "General"
