Hello Rob, I know these sources and used this info at the time. Unfortunately didn't work. I then used my graphical trick and discovered minimal differences which apparently are crucial and depend on the type of device and type of remote control. The values I found my way worked perfectly and so did the unit I made. But only to switch the heating on and off in time. Because my sight is getting less and less, I was dreading working this way again. Unfortunately, I didn't manage to get the series of zeros and ones right on my screen. regards Hans
