Settings on the "Heating engineer" level
Press and simultaneously for 3 seconds to activate the "Heating engineer" level for
selecting 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
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 (6 different types) and a d.h.w. circuit
(5 different types). The 2 types of circuits can be combined in 29 different ways. The following
plant diagrams show all possible combinations.
The controller's operating line 51 only accepts combinations that are possible.
