The Direct Digital Controller is a device that is applicable as a panel, and which is able to show, on a backlit
graphic LCD display of 128x64 pixels, all the status, operating and error conditions of each individual unit to
which it is linked. The DDC (Direct Digital Controller) controls water thermostating by controlling the switch-on

The following elements are present on the front of the panel:
 Graphic display on which all the parameters necessary to control, program and configure the plants
managed by the DDC are shown (see detail A in Figure 1).

operator to select options, set parameters etc. (see detail B in Figure 1).
