I've been working on the 24 hr log you sent me. I have converted it to an Excel file to make analysis easier.There was not a single short cycle after disconnecting outside temperature sensor for more than 2 weeks.
Would it be possible to send me another 24 hr log, without the outdoor sensor, connected, so I can see exactly what happens?
Heres a chart showing how the boiler runs over the 24 hours. The oudoor temperature uses the vertical scale on the left, All other lines use the left hand scale where 100 is either 100C or 100%. The thing I do not understand is why the boiler is switching up and down between modulations which are 20% apart when on heating, but more refined when on hot water. It's as if TPI (from the usense?) was controlling the boiler temperature. The actual room temperature stays very constant at 22C so I haven't bothered to show it.
