7.2 Cascade control
Up to 7 boilers equipped with the HMI S-control can be managed in
cascade with the HMI T-control mounted in the master boiler. The system
sensor is connected on the master boiler. All the boilers from the cascade
are connected by a S-BUS cable. The boilers are automatically numbered:
A The master boiler is number 1.
B The first slave boiler is number 3 (number 2 does not exist).
C The second slave boiler is number 4; and so on.
There are two options for cascade control management:
Adding supplementary boilers successively (traditional control).
Adding supplementary boilers simultaneously (parallel control).
1 First boiler starts running when system temperature is 3°C below
set point.
2 After 4 minutes the second boiler starts running if ΔT< 6K and the
system temperature is still more than 3°C below set point.
3 After 8 minutes the third boiler starts running if ΔT< 6K and the
system temperature is still more than 3°C below set point.
4 First boiler stops running when system temperature is 3°C above
set point.
5 After 4 minutes the second boiler stops running if ΔT< 6K and the
system temperature is still more than 3°C above set point.
6 After 8 minutes the third boiler stops running if ΔT< 6K and the
system temperature is still more than 3°C above set point.
