Shelly Zone Controller Adaptor

Simple converter board to connect a Shelly Uni to a 24vAC 2 Zone Damper setup.  The board takes 24vac in from the original manual damper controller,  parses it to the Shelly Uni for power,  then feeds two 24vac inputs into the Shelly In1 and In2 inputs.  The shelly uni then provides drives a standard 24vac 2 channel relay board which then reconnects back to this converter board to drive the standard rj11 dampers
