    "solution for the variable target flows"? I hope you don't mean by using an OpenTherm monitor?

    If your boiler is leaving rooms at 3 degrees below their set points with a 40% TPI duty cycle then I'm pretty sure that your boiler is struggling to put out enough heat for the number of radiators...

    Thanks for the recommendations for Intergas. Not sure if that will be an option with grant funding or whether it will be a "here's what we're offering" situation. Will find out on Friday!

    Evohome-munin is a python plugin for the monitoring/graphing software Munin.

  6. Evohome and OpenTherm boiler recommendations?

    Hi All,

    I know the information on which boilers do and don't play well with Evohome OpenTherm is buried in this forum somewhere, and I've read quite a bit of it in the past (and forgotten more...

    The best thing to do is buy high quality SD cards and of reasonable size if you want reliability and longevity. The write endurance difference between an el-cheapo and a good name brand like Samsung...

    Optimal start only makes an adjustment of about 15 minutes per day for the start time.

    So if you get a sudden weather swing from cold to hot and the actual needed warm up time of the room is now...

    That's about what I'd expect. The reminder beep starts quite soon, but it should run for 2-3 hours before the big red warning that blocks the screen appears. If you leave it you'd probably find you...

    A flashing red light on the BDR91 means it is either not bound or has lost comms with the Controller.

    I would fix this first before worrying about reliability of the CS92A, clear the bindings on...

    Yes, the CS92A sends its updates too rarely (1 hour between updates if no changes have occurred) and does not send every message twice like the DTS92 does. It doesn't take many lost messages before...

    What CT1 said.

    Sitting another thermometer on top of the HR92 as a comparison is meaningless because it is being heated by the radiator pipe work below and the side of the radiator differently to...

    Perhaps if the Evohome has a recent memory of the batteries being flat and you charge them externally instead of letting it go through the charging process it doesn't believe they are charged? I...

    Like I said, mine would last 3 hours off the stand when I first got it with the original batteries.

    The problem for me has always been that once the batteries are determined to be fully charged if...

    1) Hot water overrun only works if you have a boiler relay. (since Evohome needs to be able to control boiler and zone valves independently to achieve this)

    When I first got mine in 2015 it would run from batteries without complaining for about 3 hours and run another 3 hours complaining before it finally died.

    Agreed, 6 cycles per hour is optimal for a gas boiler and this is also the default. I've tried 3 and 12 cycles per hour and both have different drawbacks for a gas boiler.

    I use a minimum on time...
