5.8.5.2 Master-slave mode for the synchronisation of several controllers
Function description
Master configuration:
The internal defrost timer must be active on one of the participating case
controllers (menu 3-2, parameter Defrost Timer = INT). This controller is then the master.
Slave configuration:
The other case controllers must be configured for external defrost start (menu 3-2,
parameter Defrost Timer = EXT). These are then automatically slave case controllers.
On reaching the defrost end temperature for the respective zone the defrost relay is switched off. Cooling is
only resumed when all the control zones of all the participating case controllers have completed the defrost or
the safe defrost time has elapsed.
Defrosting example
Case controller UA M configured as master. Case controller UA S configured as slave. The start of the
synchronised master/slave defrost is initiated via the internal timer.
Note the following for this example:
The internal defrost signal is applied for the entire safe defrost time. Termination of defrosting is generally
governed however by de-energizing of the last defrost relay.
Further details of special features and restrictions are provided in chapter
synchronisation of the zones of a single contr.
