51
Heat pump sensors B21 and B71 have been reduced without simultaneously se-
lecting the common flow temperature sensor B10 (ZuFu12).
53
The number of controllable heat sources selected is too large (maximum 2).
54
To enable d.h.w. heating to adopt the setpoint and the controller’s time switch
program via the BMU, some other oil / gas partial diagram (7 or 8) must be se-
lected.
55
The last d.h.w. temperature sensor has been reduced without having selected
d.h.w. heating via the BMU.
The reason for terminal usage beyond capacity for the relay terminals (Q) is given on
operating lines 140…152, and the relay terminals (Q) is given on operating lines 142,
145, 153, 155 through 160 and 177.

•
Unambiguous diagram identification number
All basic diagrams and all combinations of partial diagrams, auxiliary functions and re-
duction parameters are defined by a clearly assigned diagram identification number.

The diagram identification number is displayed in 4 parts each comprising a maximum
of 8 digits:
Diagram identification numbers (part 1)
Diagram identification numbers (part 2)
Diagram identification numbers (part 3)
Diagram identification numbers (part 4)
This number enables Siemens Building Technologies to unambiguously identify the
selected diagram. This facilitates the identification of problems and their communica-
tion.
