5.5.6.2 Master-slave mode for the synchronisation of multiple controllers
Operation
Master configuration:
The internal defrost timer must be active on one of the participating case controllers
(menu 3-2, parameter
Abtauuhr = INT
). This case controller is then designated as the master.
Slave configuration:
The other case controllers must be configured for external defrost start (menu 3-2,
parameter
Abtauuhr = EXT
). These are then automatically slave case controllers.
Defrost process example
Case controller UA M is configured as master. Case controller UA S is configured as slave. The synchronised
master / slave defrost process is initiated using the integral defrost timer:
The following must be noted for this example: The internal defrost signal is present over the entire safe defrost
time. However, the end of the defrost process generally depends on switching off the last defrost relay.
Further details about special features and limitations are explained in
chapter
The defrost relay is switched off when the defrost termination temperature of the respective zone is
reached. Cooling is only resumed when all the control zones of all the participating controllers have
completed the defrost or the safe defrost time has elapsed.
