• Single appliance conguration
If you want to revert to single appliance conguration, you must switch o all other appliances and then repeat the auto-detection procedure, making sure to set it as Master.
In this case, the total number of recognised appliances must be equal to 1 (recognition correctly as a single appliance).
Once the appliance has been congured as a single appliance, the Reset Settings function can help to reset many parameters previously modied from Simple Cascade
to default values
If one or more Simple Cascade appliances have been congured as single, it is assumed that the Simple Cascade communication BUS is removed for their
operation
5.3 RESTORE SETTINGS AND PARAMETER SYNCHRONISATION
Parameter reset, returns the parameters in the Master appliance to their factory settings (or to a set value) (see Restore settings column in the boiler manual) and at the
same time, synchronises the parameters in the Slave appliances (see synchronisation column in the tables below).
ere are also two separate synchronisation functions for setting parameters from Master to Slave appliance(s):
- Parameter synchronisation
- Single parameter synchronisation
For synchronisable parameters, see the Synchronisation column in the Slave appliances tables.
Before performing synchronisation operations, make sure that the cascade has been correctly detected by the Auto-detection function and that all boilers
are switched on. is operation can only be performed from the Master appliance.
• Parameter synchronisation
is function is used, aer the replacement of one or both boards of the Slave appliance, to quickly congure parameters.
On the Master appliance in the Technician/Cascade/Parameter Synchronisation Menu, there is the parameter to perform parameter synchronisation.
is function causes certain parameters on the Master appliance to be changed in the Slave appliance(s). Some parameters are synchronised on the slave appliance(s)
but are not visible in the relative menu (visible when the appliance is congured as a single appliance). e list of synchronisable parameters can be seen in the Syn-
chronisation column of the Slave menu table.
• Single parameter synchronisation
e parameters in the Synchronisation column of the Slave menu table are automatically changed on the Slave appliance(s) if they are changed on the Master appliance.
is function causes certain parameters on the Master appliance to be modied in the Slave appliance(s), for correct operation of the simple cascade. Some parameters
are synchronised on the slave appliance(s) but are not visible in the relative menu (visible when the appliance is congured as a single appliance).
Some synchronisable parameters can be customised on the individual Slave appliance, however customisation is lost if one of these parameters is changed
again by the Master appliance or the 'Parameter Synchronisation' function is activated.
5.4 CONFIGURABLE RELAYS
• Booster relays
e booster pump function can only be congured on the main board of the Slave appliances, while it can be congured on both boards of the Master appliance.
is relay can be used to signal boiler pump activity (must be congured for each individual appliance in the cascade).
• Error relay
e relay programmed as an error, adopts a dierent behaviour from Master and Slave appliances, but, there is no dierence if programmed on the electronics board
or display board.
e relay programmed on Master appliance is activated when there are errors in any appliance in the cascade.
e relay programmed on the Slave appliance is activated if there are errors on the Slave appliance itself.
e error display is present on the Master appliance even if caused by the Slave appliance, while in the error history, each appliance records its own errors.
• Burner relay on
e relay programmed as ignited burner, adopts a dierent behaviour from Master and Slave appliance and if programmed on the Master appliance's electronic board
or display board.
e relay programmed on the Master or Slave circuit board shows the burner status of the appliance itself.
e relay programmed on the display board of the Master appliance, highlights the burner status of any appliance in the cascade.
e relay programmed on the display board of the Slave appliance shows the status of the appliance's burner.
On the main screen, the ame symbol represents the burner status of the appliance itself (the Master appliance does not replicate the burner status of Slave
appliances).
