    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...

    It looks like the HCE80 works fairly autonomously apparently calculating and responding to zone demands itself.

    For instance you will see it opening actuators for zones even when the Evotouch...

    I would clear all binding on the DHW BDR91, and bind it again. It may be double bound.

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

    Nothing you can do about it I’m afraid. At low zone demands < 10% (24C) I observe the HCE80s TPI the UFH pump even though the boiler...

    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.

    Basically the CH 2-port is Normally Open and the DHW valve Normally Closed.

    When there is a Priority DHW demand the CH valve is closed and DHW opens, so all flow is to the cylinder.

    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?

    If there is no heating demand 0% then the boiler won’t fire and the radiator valves won’t open.

    Try setting zone(s) 2C above the current temperature reading to test whether they heat up.
