    I think we will be waiting a while for a new firmware update.
  2. You need a heating engineer to look at your boiler

  3. Storage Combi of choice these days

    Asking for a friend, no seriously. He doesn't have the space or need for a full blown Unvented cylinder and system boiler. But can fit a Storage Combi.
    In 2022, what would be the boiler of choice....

    For the moment as a work around why not just set the Max flow needed as 5C lower than what you actually want. See if that helps.
  5. Do you have the ability to measure the actual...

    Do you have the ability to measure the actual Flow and Return temperature of the boiler, rather than relying on the boiler's read out?
  6. I am still wondering why Resideo just have rolled...

    I am still wondering why Resideo just have rolled out the latest firmware to all installations, rather than updating them when people, clearly only on this forum, request it.

    Everything on the Domoticz side seems fine. It just seems like your OT isn't responding fast enough with the Flow and Return temperature queries. Just leave it for a while and see if things improve...

    Another thing to look for is messages in the Domoticz log wrt OpenTherm. Is it detecting the OTB?

    I have been running my CS92 sensor using the controller's wall mount PSU for a few years now. I just put it through a voltage step down to 3.2V before attaching the wires to the battery terminals.
  12. I think two things have happened together. The...

    I think two things have happened together. The Evohome has been updated to the latest firmware and your Domoticz install is old. Evohome now longer requests this information from the OTG. So the...

    Any chance you can show how to get to the installer menu

    I did suggest this to be the case several posts ago. So am not surprised this was the issue.
  15. I am trying to see if I can force the newer...

    I am trying to see if I can force the newer BDR91T to bind as a Heat Pump relay. Because that does a TPI cycle only once per hour.

    All the settings for the Quick Actions are within its own menu, including how much you want Eco set to. But when you turn it on, it won't ask you by how much, it uses the value you set earlier.
  17. I think you have used a combination of zone...

    I think you have used a combination of zone wiring and evohome binding that is causing the problem. What I would do is use one or the other. You can configure CH, HW and boiler relays in the Evohome....
  18. That was the hack that I had programmed into...

    That was the hack that I had programmed into Domoticz for when I was using a BDR91 for my UFH. For any Heat Demand greater than 0%, I was sending a 100% Heat Demsnd to the UFH BDR. That stopped it...
  19. I still think that a CH valve on an OT system is...

    I still think that a CH valve on an OT system is unnecessary except for when the DHW switches on. That stops the sudden in-rush of HW into the CH circuit. Otherwise I think the TPI on the CH valve...
  20. When you say Boiler has been OFF with 11% heat...

    When you say Boiler has been OFF with 11% heat demand? Do you mean the boiler isn't firing? Because with OpenTherm the boiler should be ON with absolutely any heat demand, however small.
  21. What about turning the spindle and removing the...

    What about turning the spindle and removing the motor head? Will that open the ball completely and keep it open?
  22. Yes I use the boiler's pump output to run both...

    Yes I use the boiler's pump output to run both the pump as well as open the CH zone valve in my S plan. I don't use a CH BDR.
    Doesn't a system boiler have an auxiliary pump output. What if you need...
  23. As a temporary fix just using the A B C terminals...

    As a temporary fix just using the A B C terminals of a single BDR to get your HW priority going as well as operating the CH valve. As you probably know, mechanically locking it open doesn't actually...

    I have encountered another bug that has been introduced with this firmware version but it relates to the HM80. There Honeywell's suggestion was to set the Mixer Valve as a Zone Valve. But similar to...

    Yes that is the load scaling bug that I referred to. Trying playing around with the various load scaling parameters and see if the behaviour of the CH BDR changes with each change.
    Like I said,...
