did you connect the 12V supply  from UH1 to the 12V into the Heatmiser plug in board? This provides an isolated 12V supply to the plug in module


When the 1st response does not work, which are the thermostats that see the command and which do not. Can this be isolated to the ones that are connected to 1 of the UH1s?


Why are there 2 UH1s?
