    I take it you're not on 19.31 or 19.33 ?

    That's a well known problem on older firmware versions (discussed a lot on this forum) and it has bitten me personally twice, but it's a long time since it...

    Depends what you mean by compatible. :)

    The fitting screws on and sort of works? Sure.

    Works properly and moves the pin across the full range the valve needs and controls the radiator...

    I trialled an HR91 on my system (which already had HR92's) when they first came out and I did not find the HR91 compatible with the valve bodies that I...

    Yes I'm still really annoyed as well.

    The offer for a free upgrade to the new electricity monitor ends on the 7th, I just completed mine and it has shipped - I just had to pay 3 postage.

    The description in the manual is a bit misleading relative to how it works in practice I agree. What I can gather from observing my system and also some conversation with the Honeywell guys in this...

    Yes this is a well known issue. Do a forum search for "phantom override". And yes, the fix of rebooting the HR92 at the "right" time of the hour does work, I've done this on a few of my HR92's across...

    If you continue to have trouble with the valve not fully closing, consider changing the Stroke setting to 1 - this increases the force used to close the valve and increases how far down it pushes the...

    I would still check the set point on the actual HR92 itself when the radiator is getting hot when it shouldn't, as if there is a binding mistake on the HR92 the controller and wall thermostat will...

    Interesting read, albeit from those with a vested interest in keeping the gas pipe infrastructure intact and making profits... ;)

    Lets pick out a few pieces.

    That's a great point.

    Installing the original natural gas network would have been quite an upheaval and a major project, but the dividends were obvious to anyone involved - the comfort and...

    Did you actually check the set point on the HR92 which is coming on unexpectedly to see the set point is indeed following another zone ?

    Or are you just going by the radiator getting hot ? If the...

    What firmware version are you on ? And if you are on 19.31 or 19.33 do you have load scaling enabled in full or partial mode ?

    Knowing the answer to those questions will decide whether what you're...

    True,

    But that's about the highest you can go with existing boilers and pipe networks. Pure Hydrogen is infeasible without all new boilers an an all new pipe network.

    Has there been any real movement on this though or is this just wishful thinking on the part of the fossil fuel industry?

    You can't just pump pure Hydrogen gas through the existing natural gas...

    Yep, I had to give up on "Normal" / "Full" mode as it is too aggressive on my system causing rooms to struggle to meet their set points. Partial works well for me.

    Unfortunately the DTS92 is the cheapest option. The HCW80 and HCF82 are more expensive despite lacking a screen! (At least they were when you could buy them if they have in fact been discontinued)

    By free standing do you still mean as a sensor as part of an Evohome system ?

    If so yes there are several that work. The two main ones are the DTS92E and the Y87RF, both of which are available on...

    I would just replace and carry on.

    A lot of the learning and adaption is actually done by the individual HR92's so resetting the controller won't reset their adaption anyway.

    What do you mean by "switching the heads" - do you mean swapping the entire HR92 ?

    If so it can't be a faulty HR92 if another HR92 in the same place is also just as noisy. ;)

    I agree with the...

    While you're there Andy, any idea when 19.33 is going to go into general release and the Beta testing period will be over ?

    We've been beta testing these two beta versions since April now, I think...

    Single room zone vs multiroom zone is all about how many temperature sensors there are in a zone and where they are.

    When you bind devices to a zone the first one you add will be the sensor (unless you choose the Evotouch as the sensor) and the rest will only be actuators.

    Are you sure the device is connected to WiFi/Internet properly, and showing the Internet icon at the top left ?

    If not, the smart features disappear from the settings menus.
