@morgan, probably best listening to @heacol re compensation curve.  I was close, but not quite right.

My main screen and current compensation curve.  What does this tell me and is it good?

@morgan I would bring the 50 down to 45 and the 30 down to 25.

To shift that curve, all you do is push the up and down on this screen, you do not have to re-adjust the curve every time. 1 up or down will have that approximate efffect on the internal temperature.

Cheers Brendon.  I’ll give it a go.  Presumably nothing will change until I press the tick button?  Just in case I press the wrong buttons and adjust it badly.

@heacol 

Actually looking at the picture, I’m not sure I understand.  Up and down buttons?

@morgan Yes, + = temperature /compensation curve up = woamer house and vice versa. You only have to adjust the curve once.

@heacol 

All that does is alter the single number in the centre of the screen up or down.

@morgan That is correct, it is shifitng the compensation curve up and duwn. Use it as a level. One level up will raise the curve and therefor the flow temperature resulting in a rise in the house temperature, and vice versa.

But I don’t see the 45-25 referred to.  I’m confused aren’t I?  Not difficult 😆

@morgan, the screen with the big graph and numbers is where you define the baseline graph.  Yours is currently a 50-30 shape. This defines what outside temps will generate flow temps of 50 and 30 (and all the values in between) when your home screen has a big zero on it.  If you make the big zero -5, then it uses your 50-30 graph but moves it down 5 so that 50-30 becomes 45-25.  You won't see that but it will use it.  That's what Brendan is saying to do.

You could change the big graph to 45-25 and leave the big zero at zero, but that's a bit more complicated.

Aha. That makes sense. To do the same and keep the ‘big 0’ do I press and hold the left button and go to an edit screen?  I’ve been Googling.  I know, dangerous 😆 but I have to get on top of this system if I can.  Really appreciate the support here.
