Perhaps I’m missing something Mike or is my controller different somehow as 2093 is words not numbers?
Appreciate what you say about antifreeze cycles but outdoor temp was well up and think it was identified as how the compressor valve arrangement needs heat is when it stops or something like that..
thanks Sarah, that’s really useful information. I will tone down the post, don’t want to upset anyone, just wanted to help fellow users!
Regarding the accuracy of the data I shall provide supporting information- it’s the proper level 3 kit from OpenEnergyMonitor, professionally installed but your mention of Samsung results got me to do a comparison (which I have not done before), for last 7 days the controller tells me COP of 6.71 against the Level 3 kit showing 6.73 so looks like a good validation. I will look into measurement boundaries as well to see if that impacts my results. Thanks again.
@JPB Sorry, the numbers are in the manual, but not on the wired controller. The setting is ‘thermostat only on off’. With the other settings, if LWT rises above target because your emitters cannot dissipate the heat pump’s minimum heat production, then it will cycle off and then back on repeatedly. With this setting, the LWT rises until the emitters match the minimum heat production and the heat pump only cycles if the thermostat target is reached.
Mike, Many thanks for the explanation now changed. We have added more of our UF this year so its doing quite a lot of work than it used to.
I’m also puzzled by auto on the front screen others refer to but I cant seem to access.
Now have Snet pro installed and the nasa data is also being logged on sheets which confirms I never go below 20hz which other seem to…I suspected this doesnt help my cycling…perhaps another setting somewhere.
