Jablotorn GD-04 radio module for DAVID unit

Allows inputs (A to D) to be activated using wireless buttons and Oasis series detectors. It also allows the status of David's output relays (X and Y) to be passed to Oasis Series wireless UC and AC receivers. The RC-8x series wireless pushbuttons can also be used to locally control the X and Y relays in the David (i.e., the connected appliance can be controlled by both mobile phone and remote control). In conjunction with the TP-8x series wireless thermostats, the heating can be controlled (locally but also remotely by mobile phone).
