Space heating is controlled by Danfoss thermostat and hasn’t been on as set to 20c and not needed . Here are my results , on the 10 Fsv’s only one needs noting as the rest is to do with room heating /cooling. So 10:51 is DHW Tank heating set at 54c 10:52 40c max/min 

The 30 values written on the attached

Next is the timer for Daily . The first two slots are on off as you will see.

The last picture shows when timer settings goes back to Home Screen when Esc is activated . 
I hope this helps Also attached is this note at the end of Daily settings in the Manual. FSV VALUE?

@alfapat 

OK Im a bit stumped, but the good news is that someone in another thread has got it working (it may be a different generation but at least it gives a point of comparison), I have asked them to comment and you might wish to PM them.

I think the cryptic note you posted refers to 3031.  This is a bit strange and suggests somehow they have economised on output or internal registers and combined two functions in a confusing way.

Can you check FSV 5041 which should be set to 0, and also 4011 and 4012.

Perhaps set the on time (initially) to something where you can monitor the operation (eg 5 mins after whatever the time is when you set it) and watch what happens and also check the actual water temperature at the time, temporarily modifying 3023 (or the target DHW temp set on the user display) if necessary so it should definitely trigger.

So I have done a short set up and it worked!I could get any lower difference than 5c so hiked up to 55c and set the timer , it seems to work now . 

My main trouble seems to be that the controller is not saving my set times , when I go over the slots they have changed in some and not others. 

I will go over them again this evening , but its so annoying! Thanks for your help ....again.

Thats good news indeed, you are very likely almost there!
