no blocking
|
2
|
blocking increasing the number of stages
|
3
|
blocking decreasing the number of stages
|

- The calculated boiler capacity value will be displayed by parameter DISP-02 and represents the boiler power in kW.
- The operation mode will be displayed by parameter DISP-03 and the output “OperationMode” and represents:
- The number of hours before a cyclic boiler changeover will be displayed by parameter DISP-04. This value is the difference between the maximum runtime, defined by parameter SYS-08, and the actual runtime of the boiler. In case that there is only one heat generator in a group, the value of DISP-04 is set to “999”.
