Overnight 42c target.  the first curve is my hot water tank run which shows the system is capable of high flow temp.  

 

OK. Please confirm heat curve and max flow temp settings last night.  Are you 100% certain noise reduction mode is off.  Something is capping flow temp in space heating mode, the question is what!

If you have 2 zones on the controller check settings for both.  Not sure how 2 zones are supposed to work TBH!

I sit possible heat pump is working at max output so whats capping the FT is just heat loss?  Power consumption suggests thats possible.  Can you get data on energy delivered?
