This is just a quick post at the moment because the project isn’t done and I am distracted by other things… The thermostat for the central heater in my house became unreliable a week or two ago. My wife rang around and a new one from the manufacturer of the heater was going to be $450 AUD. So, it seemed obvious to make my own. I’ve just installed the 1.0 of it, with the board layout and manufacture being done by Doug once again.

Other people seem to lack a PCB manufacturing back neighbour. I highly recommend you acquire one if possible.
