Calling up parameter level 2
Parameters are split into the following groups:
■
–
"General"
–
"Boiler"
–
"DHW"
–
"Solar"
"Ventilation"
–
"Heating circuit 1/2/3"
–
"All parameters"
–
In this group, all parameters are shown in ascend-
ing order (the parameters for the "Solar" and
"Ventilation" groups are only shown if a solar con-
trol module, type SM1 and/or ventilation control
module, type LM1 are connected).
Heating systems with one heating circuit without
■
mixer and one or two heating circuits with mixer:
In the following, the heating circuit without mixer is
designated "Heating circuit 1" and the heating cir-
cuits with mixer as "Heating circuit 2" or "Heating
circuit 3".
If the heating circuits have been designated individu-
ally, the chosen designation appears.
