    New home, mammoth Evohome install

    Just placed a huge order with the EvoHome Shop for my new house, after getting to grips with the existing set up (Danfoss controls).

    Typically this happens when the controller is not docked properly and its battery is discharging and running low.

    I think the recommendation according to the installation manual, when you have HR92s, is to have a wirelessly connected BDR91 or R8810 boiler control, not a wired connection.

    Thatís where I got mine but I had to wait a while, as production was moving to a new factory. It was worth it though, but the EvoHome shop donít have much experience of it, so couldnít provide much...

    Iím sorry but I canít seem to view your diagram.

    Why use Heatmiser at all? If you donít want to use HCC80 you can instead control each zoneís actuator by a BDR91. Then use a T87RF, DTS92...

    Hi Saaj,
    Do you find that HCC80s in combination with OpenTherm works well?

    The reason I ask is that I am moving house next month and expect to be installing this setup, probably 4 HCC80s, 1 per...

    I think it is a mistake in the Xclusive's manual. If you look in other Intergas manuals, for instance my boiler, you'll see the following descriptions.

    That is the correct behaviour. You've set the minimum temperature for OT demand to 25C, so the minimum seen should be 25C and not any temperature less than this.

    Another way to look at OpenTherm low load low/off control is that Evohome has no idea what the lowest flow setpoint is. It can read the Max CH water setpoint (which is often wrong e.g. Intergas...

    I never said it was a problem, I think you doubted that this mode of operation occurred, hence my explanation.

    Not quite. You will see this with OpenTherm and no heating valve when the low load algorithm comes into play. (I seem to keep repeating myself on this).

    Yes, it appears to be, every 10mins or so. A plot of the flow temperature request might show short 10C (off) requests.

    Hi Dan,

    With EvoHome and HR92 on all radiators you really should keep the CH valve open. I have a Normally Open valve fitted which closes when DHW is being heated.

    I guess what is happening...
