Rapid CT set-up

– When the CT value is not known and only used at the moment of the installation, the P.01 parameter for CT primary can remain set at OFF while all the others

can be programmed.

– In this case, during the system installation and once the controller is powered up, the display will show a flashing CT (Current Transformer). By pressing

▲ ▼

the CT primary can be set directly.

Once programmed, press MAN/AUT to confirm. The unit will store the setting into P.01, and directly restart in automatic mode

Parameter table

– Below are listed all the programming parameters in tabular form. For each parameter are indicated the possible setting range and factory default, as well

as a brief explanation of the function of the parameter. The description of the parameter shown on the display can in some cases be different from what is

reported in the table because of the reduced number of characters available. The parameter code can be used however as a reference.

Note: The parameters shown in the table with a shaded background are essential to the operation of the system, thus they represent the minimum

programming required for operation.
