@hcas - exactly so. I did read one other persons similar experience but the overshoot was lower if I recall correctly. I can only make this comparison because I have an electric meter just on the cable for the heat pump, but as it is not close the FTC unit I cannot connect an output from it to the FTC which would then replace the unit's own guesstimate with the metered value. This is what most people who have invested in metering will have done.

Mitsubishi EcoDan 8.5 kW ASHP - radiators on a single loop
210l Mitsubishi solar tank
Solar thermal
3.94kW of PV

@toodles No. But I wasn't forced there either and The King had nothing to do with my trip LOL.

Just when I returned I had no internet which has now been resolved.
