If you wish to drive your Deltadore or Ecotherm Heaters with the X2D PLC (or X2D CPL), I programmed a small interface that allow to easily send commands thru a serial line (UART 9600 bauds). The serial commands are converted and sent directly to the power line.

Available commands :
Heating commands (« Z1, Moon ») - 9 possible zones, 6 levels (Moon, Sun, etc...)
receiver association (« Z1, Assoc, d=1 ») 6 load shedding channels (d=1 to 6; 0= disable)
Associate a the adaptor to the existing installation like Driver230 CPL, or other.
The usage of UART allow easy interfacing with Domoticz or other automation boxes.
