The configuration diagram shows all function blocks active in the plant type. In this
example, they are the following function blocks:
• Boiler sequence manager
• Boiler 1
• Boiler 2
The configuration diagram shows the inputs and outputs that are preconfigured.
If required, additional inputs and outputs (e.g. flue gas temperature sensor, burner
operation checkback signal) can be assigned to the free inputs and outputs in the extra
configuration.
Also, it is possible to see which extension modules are required. For plant type K5.2,
extension module RMZ787(1) is used as standard. This is shown on the Basic configura-
tion menu, operating line "Position 1".
If required, the output for the first or the second boiler pump can also be configured to
some other output. It is also possible to change the type of extension module.
On function block “Boiler sequence manager“, the main flow temperature sensor (N.X1)
and the main return temperature sensor (N.X2) are preconfigured.
This can be checked on Extra configuration > Boiler sequence manager > Inputs.
On function block “Boiler 1“, the boiler temperature sensor is configured to terminal
N.X3. The burner is preconfigured to outputs N.Q2 and N.Q3, the boiler pump to
A7.Q1, and the shutoff valve to the relay with changeover contact N.Q1.
For boiler 2 – analogously – N.X6 is preconfigured for the boiler temperature sensor,
N.Q5 and N.Q6 for the 2-stage burner, N.Q4 for the shutoff valve, and A7.Q2 for the
boiler pump.
This can be checked on Extra configuration > Boiler 1 (or Boiler 2) > Inputs (or Outputs).
