    I confirmed S4 is the DHW cylinder temperature reading. Also indicated I had an issue with my Priority DHW setup.

    One of the DHW BDR9s that was supposed to be normally closed and connected in...

    I currently see:

    S1 95.2
    S2 46.7
    S3 - (will try priority DHW later to see whether this returns DHW temperature)
    S4 53.2
    S5 -2.3

    Temp Flow 63.7
  3. Paul, are my guesses correct? Do you know?

    Paul, are my guesses correct? Do you know?
  4. Intergas Diagnostic Software S1-S5 temperatures

    Does anyone know what the S1-S5 temperatures logged in IDS are?

    S1 Flow sensor?
    S2 Return sensor?
    S3 DHW sensor?
    S4 ???
    S5 Outside temperature sensor?


    Thanks!

    Ian, you can configure how many hours optimum start will pre-heat, maybe you need to increase that parameter.

    It took a while (largely due to lack of support for this in the UK) but I now have the HM80 controlled solution for my single-zone UFH in place. And it works great, I no longer see the 1 degree...

    I donít see that as the issue. Evohome should be able to balance any heat loss for any zone when the set point is reached. As it stands, at set point, the zone still has a 50% heating demand leading...

    I think the key difference is that I am only heating our UFH zone in the evening. In an experiment, running 24/7, Evohome could maintain a stable temperature when the set point was set to the...

    What schedule and set points are you typically using for your UFH zones? Are you combining with rads via a lower temp mixing valve? Using OpenTherm?

    The HM80 is a fuzzy logic controller, so I am hoping it will offer better temperature control for a single zone UFH, than BDR91 TPI, just like you see with the HCC80.
