Adding auto-adaption to a Midea heat pump controller
Posted by: @derek-mI am pleased to see that you are resisting the urge to 'tinker'. I think that you will find it could takes several hours for the IAT to reduce and stabilise.
It's called masterly inactivity...
Posted by: @derek-mOne improvement that you may wish to consider is varying the offset dependent upon the size of the deviation.
Something along the lines of:-
If the deviation is <0.5C, do nothing.
If the deviation is =>0.5C, offset by 1C.
If the deviation is =>1.5C, offset by 2C.
I had had similar thoughts, thinking about recovering from an overnight setback, for example, when the deviation is likely to be greater.
I have just had a peek at the live minute data for the last 12 hours (auto_adapt went live at 0800 this morning) and the LWT and energy in have gone down a bit, whether due to the increased OAT and/or the auto-adaption, and the IAT has dropped by 0.1 degree C...
This is on a par with watching the paint dry. But that's OK for now, I just need to get a feel for what the increments need to be by trial and error.
