    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.

    Adding 10% Hydrogen to...

    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.

    This has been asked of the Honeywell guys on here a few times (including in the beta thread) and Honeywell's position seems to be that per-zone optimal start on/off is not coming back, however if you...

    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...
  10. Single room zone vs multiroom zone is all about...

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

    1) Single-room zone - there is only one active temperature sensor for the zone...

    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.

    Unfortunately there is nothing you can...

    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.

    Hang on - is it true that you can't enable load scaling if you don't have an explicit boiler (appliance) control relay ?

    I haven't seen this mentioned before and since the heating relay also does...

    That's a very good question which I don't think anyone has asked before or has a definite answer to.

    However based on what I know about how the system communicates I would say that optimal start -...

    So I've just received the email notification from loop today.

    The "legacy" version of loop is being switched off on the 19th of December and while they'll send out one of their new electricity...

    The ATF600 actually came out in June 2015 with the WiFi controller, I bought my WiFi controller in late 2015 and used an ATF600 wall mount kit. (It even says it came out on June 2015 on the...

    The downsides to multi-room zones are:

    1) You can't use a remote sensor like a DTS92E, only the built in sensor in the HR92's. (If you add a remote sensor to the zone it will just provide a...

    The controller still uses heat demand with a BDR91 - it controls the percentage of time that the relay is on in each (by default) 10 minute cycle.

    So yeah, it's "on/off", but the proportions of on...

    From what I've seen, zones that struggle to heat up can end up with their heat demand not scaled down nearly as much as zones which easily heat up or tend to overshoot - I think that's part of the...

    I see you are graphing the measured temperature from both HR92's in the zone - is the zone configured as a single room zone or a multi-room zone ? If the former, which one is configured as the sensor...

    You can pair up to 4 controllers to each BDR91.

    So in the case of a two Evotouch system you would have only one controlling the hot water relay (if you had hot water control) and then both...

    As far as I know Evohome is an EU/UK product only.

    Six per day per zone. I do find myself hitting that limit if I try to get "clever" with my schedules.

    People have been asking for this for...

    Try switching Advanced Load Scaling to "Partial" mode. This reduces how much the heat demand is scaled down. I found the "Normal" mode scaled the load down too much on my system and I saw similar...
