I recently installed weather compensation on my Ideal Vogue Max and I'm very confused by the settings menu item called "outside sensor slope", which lets me select a number between 0 and 40. The manual states that this adjusts boiler performance relative to the building insulation, but doesn't tell me what unit that is measured in. Also, the picture in the menu and manual looks very much like a weather compensation graph (outside vs flow temperature), which I can also adjust by changing the room temperature (nominal, not actual).
When I change the room temperature, the boiler immediately reacts as I would expect it to, but when I change the outside sensor slope, nothing happens at all. Does anybody know what that is supposed to do?
