Coding level 1

Calling up coding level 1

On weather-compensated control units, codes are
■
displayed as plain text.
■ Codes that are not assigned, due to the heating sys-
tem equipment level or the setting of other codes,
are not displayed.
■ Heating systems with one heating circuit without
mixer and one or two heating circuits with mixer:
Below, the heating circuit without mixer is designated
"Heating circuit 1" and the heating circuits with
mixer as "Heating circuit 2" or "Heating circuit 3".
If the heating circuits were given individual designa-
tions, the selected designation and "HC1", "HC2" or
"HC3" appear instead.
The codes are divided into groups
■

"General"

■ "Boiler"
■ "DHW"
"Solar"
■
"Heating circuit 1/2/3"
