we have been commissioning a Nibe air to water heat pump installation,we had a few issues with operation and not coming back on as it should and going off while a heating demand was still calling,after talking through the issues with Nibe we came to the conclusion that the degree minutes setting was only -60 which was adjusted to -200 this seems to have cured the problem,although this was explained on our first training course I cant get my head wrapped around it,can anyone explain this in plain English?and does anyone else find these controls so overcomplicated?
