Who understands Hc1ActualFlowTempDesired ? 
I’m trying to work out why a chosen heat curve like 0.45 works when it’s cold, but then when it warms up a little outside I get room overheating. Despite using active to give room influence.
When using Active mode, this desired flow temp changes depending on how close/far away, the actual room temp is from the target room temp
Examples (me switching the WC curve and flicking between Inactive / Active)
Room Temp: 21.5, Target Room Temp: 20.0
Desired Flow temp reading shown
Curve 0.2 (2.2 diff)
Active: 21.4
Inactive: 23.6
Curve 0.4 (2.5 diff)
Active 23.5
Inactive 26.0
Curve 0.6 (3.0 diff)
Active 25.5
Inactive 28.5
So that makes sense, ‘room influence’ lowers the desired flow temp
and it’s sticking to the 2.5C flow temp difference per 1C of per room temp difference (as seen in the WC curve tables)
BUT, what I don’t understand is why the heat pump doesn’t always seem to adhere to the target when in Active? Especially when it starts to cycle
You can see in this trace the desiredflowtemp is shown in the grey line
All looks good when it’s cold and is in steady state
But when it warms up and starts cycling, it almost ignores the target temp
Let’s look closer
I appreciate that the flow temp rises so that Energy Integral can eventually stop the cycling.
But this behaviour of starting bang on (or above) the desired flow just doesn’t seem right to me.
It’s like it’s sort of running hotter than it should, higher than the curve it’s chosen.
My next experiment might be to see how desiredflowtemp looks in Inactive mode.
