So much of that resonates with me (and I think I have you to thank for re-visiting AA mode again). I've attached a couple of charts from the past 24...
I'm assuming the continued IAT rise is the lag effect of the three incremental/cumulative rises in target temp (I guess LWT was at it's highest / rads...
I have a theory. When thermo diff adjust mode is ON it opens up a bunch of parameters to help us control/limit it's behaviour. When it's OFF, it's unr...
My thoughts are on the same lines. Also, once OAT decreases, it will result on longer 'on' times and shorter 'off' times. I'm inclined to leave things...
+3 would be my choice. How long have you been in AA mode (I'm wondering if it has started a little high in term of target temp and needs a few more da...
Here's the scores on the doors for day three in AA mode (quite interesting - sad but true). Target temp appears to have been dropped by a further 0....
Thanks. Quite accurate - in fact I ran at a fixed flow of 38C last spring as a happy medium of still being able to heat the house at minus temps, bu...
From my experience the upper limit was ignored when thermo diff was OFF (I'd set it to 42C - it blasted through to 48C in one test). It will be intere...
@derek-m I guess not (or with not enough attention to detail) lol. I've also sussed out since that they also left the pump on a setting that gave a fl...
I've left my system in AA mode for now. Here's a representative hour from last night. Interestingly the target temp appears to have dropped by one deg...
@sunandair I'm not sure I fully understand all the maths, but that's very useful, thanks. As a side note; I notice you have three towel rails. The r...
