    No it is definitely round as when you fly to Australia from the UK it is quicker going than coming back because going it is downhill.

    Hope they have sorted out the lack of a Max CH temp setting for opentherm compatibility (or at least allow you to change the max % to something less than 100%) with all those boilers out there that disable their dials when connected to opentherm.

    It makes a bit of a mockery of opentherm savings when your condensing boiler never goes into condensing mode as it tries to sit at +80 flow except for the small periods when every zone in the house is within 1deg of setpoint.

    Unless the OTB is intelligent enough to simply respond and relay a new OT command to the boiler, I cannot see how a new Controller firmware will fix this for the handful of boilers that need this optional parameter.

    It sounds like I have a learning curve ahead to study more about Opentherm. Never mind choosing efficient good quality radiators!

    Choose a boiler that has been currently confirmed to work correctly with the OTB, rather than hedging your bet on better future support. Only a small minority aren't and even for them, adding an OTGW is an easy solution if proper OT functionality is required.
    Shameless product placement: I have an OTGW for sale :-)

    Try setting the Tmax on the boiler BEFORE attaching the Opentherm bridge. I have seen this work in most cases.
    I work for Resideo. However, any views expressed are mine and not those my employer.

    This could be huge.
