Further to the above I discovered a bit more/had an additional thought about Daikin compressors. Firstly Daikin do make their own compressors so its ...
I must say Im also coming to the conclusion that there is a problem of this nature. OP has optimised the initially high flow temperature and its now ...
Very much agree. I think OP is over-concerned about this because, as you say, cycling is 'designed in'. Also very much agree We may be spli...
'and thus its capacity' assumes that output is a linear function of modulation frequency. But I dont think thats the key point so lets not argue over ...
