With the HMI T-control mounted in the master boiler it is possible to
manage up to 7 boilers in cascade. The system sensor is connected to the
master boiler. All the boilers in the cascade are connected by an S-BUS
cable. The boilers are automatically numbered:
B
C
There are two options for cascade control management:
4
The cascade control management can be changed with parameter NP006.

Important
The settings for these temperatures must follow the screed
layer's recommendations.
Activation of this function via the parameter ZP090 deactivates
all other regulator functions in the zone.
When the screed drying function is active on one circuit, all
other circuits and the domestic hot water circuit continue to run.
It is possible to use the screed drying function on circuits A and
B. The parameter settings must be made on the PCB that
controls the circuit concerned.

Important
Every day at midnight, the screed drying function recalculates the
start temperature setpoint and decreases the remaining number of
days.
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.
Adding supplementary boilers successively (traditional control).
Adding supplementary boilers simultaneously (parallel control).
