    Maybe try changing the routerís DNS servers manually to e.g., 1.1.1.1, 8.8.8.8 to see if that helps

    Does your postcode work in Accuweather?

    Apparently thatís the service used by the controller, but the App uses a different service.

    Today all of the zones on one of my controllers and some of the zones on my second controller stopped responding, displaying hourglasses.

    I have a Zehnder ComfoAir/Cool Q600 and Evohome. They work independently.

    It keeps CO2 levels down and boosts automatically if higher humidity is detected for instance when showering.

    You will need 2 BDR91s, 1 for your 2-port valves and the other for your Intergas DHW NTC.

    On a DHW demand, 1 BDR91 opens the DHW valve and closes the CH valve.

    The other BDR91 (also bound...

    I see this same behaviour with my setup OpenTherm + 4xHCE80.

    Ideally Evohome would allow you to set different max CH and DHW OpenTherm temperatures, but unfortunately it doesn’t. And with some boilers the default 80C or 90C is too high.

    Evohome support of DHW priority has only just been added to its firmware. Previously if you had CH and DHW valves you would wire them to the DHW BDR91 such CH closes when DHW opens.

    As I understand it, this parameter sets the closed to open, 0-100% (90 degrees) actuator time.

    What do you observe when there is a 100% demand, how long does it take to open the valve?
