Settings on the “Heating engineer” level
Press
and
simultaneously for 3 seconds to activate the “Heating engineer” level for se-
lecting the plant type and the plant-related variables.
Selecting the plant type on operating line 51:
The required plant type must be selected on operating line 51 using buttons
and
This
activates all functions required for the respective type of plant and shows the associated operat-
ing lines.
A plant type is comprised of a space heating circuit (5 different types) and a d.h.w. circuit (4
different types). The 2 types of circuits can be combined in 21 different ways. The following plant
diagrams show all possible combinations.
The controller's operating line 51 only accepts combinations that are possible.
Example of a setting:
