    That's interesting. I have a (fairly large) oil-fired boiler and have left the settings at default because of a lack of explanation of what they do and why they should be set to a particular value....

    If you are using masonry drills then it sounds as if you haven't yet experienced the benefits of an SDS drill - they are orders of magnitude more effective than the old style hammer drills that we...

    Sorry, that's nonsense (and I hope that anyone considering this is already aware of cable colour schemes). Wiring to the old-style thermostats is typically 6243Y (flat, 3 core + earth) cable ......

    It would be far preferable to sink a back-box to house the power supply and to use the old thermostat wiring to provide a mains supply from the wiring centre.

    Sorry, the resistor suggestion just doesn't make sense. Also, the forward voltage of an LED is significantly more than a silicon diode so what sounds like an attractive idea would not work. The OP's...

    Because a forward conducting silicon diode will drop about 700mV whereas the voltage drop across a resistor is subject to Ohm's law and will vary with current (and resistance, of course)

    Replying to my own question (in case it helps anyone), the answer is Yes.
  8. Re-binding the heating BDR91 to 2 controllers

    My system has: 2 controllers, 2 BDR91s driving heating and DHW zone valves, and a large number of HR92s. After some mains interruptions the heating BDR91 is not responding to commands from either...

    I had a large heating and plumbing replacement that was too large for me to tackle - I think it eventually took 60-80 man days. The evohome side did not go well. The original installers eventually...
  10. Increasing HR92 wireless range by adding a cable

    A while ago I think there was a discussion about plugging an ethernet cable into a port on the HR92 to increase range, but I can't find the discussion. I have one rad which is quite a way from its...
  11. Thanks for the reply.

    Thanks for the reply.
  12. Setting the Evohome schedule - via a web interface?

    AFAICS it isn't possible to edit the schedule via the TCC web interface so that leaves doing it directly on the controller or via the phone App. Is there a way to do it via a web browser?
  13. Once the DHW loop is full of warm water there's...

    Once the DHW loop is full of warm water there's no need to run the circulation pump, doing so just stirs-up the water in the cylinder. When the cylinder is up to temperature the water is leaving at...
  14. Using a CS92 to control a DHW circulation pump ... ?

    Because Evohome can't be used as a timer my DHW circ pump is controlled by a standard CH programmer. I was about to add a pipe stat and then thought ... perhaps I can control it with Evohome by using...

    Thanks!
    Presumably there's somewhere in my profile to say yea or nay to receiving emails - I'll change it.

    I didn't receive an email from Honeywell but noticed last night that the heating wasn't responding to changes made on the app, despite the "service status" being green. Now the Domoticz data is...

    Thanks again, Dan.
    Everything seems to be working so I can't justify time playing with an HGI80, especially if the APIs are so limited.

    I'd tried setting that field to "0,0,1" but not "1,0,0" - success!

    Batteries - typical life and which type?

    My system is approaching 15 months old so I'm starting to think about battery replacement. I've got 26 HR92s so that's a lot of batteries.

    Having looked at battery specs and reviews I'm undecided...

    During the summer the HR92 motor won't be running but the electronics will still need some power, so it might be worth removing the batteries (or slipping a piece of paper under a contact). Has...
