agree with the above.
I agree with your point about off = unrestricted. When my LWT went up to 48, it was in the process of raising the IAT from 21.5 to 22.5. The set po...
I don't think so. It takes about an hour or so to heat from mid 30s to 48.5. I would have though any residual peak from the HW would be long gone? B...

I was going to start a new topic but I'll join this one if that's OK. I've been running AA for about a year and am pretty happy with it. It uses abo...
@mcwatson1974 can you explain how you normally use the system? What's on the FTC screen, how do you set the zones and switch the heating on and off...
