    Are you sure it is not because, with only one radiator calling for heat, the flow rate through the boiler is too low? I have a WB boiler and I find that, if the number of radiators calling for heat...

    Indeed. But a BDR91 only performs TPI to the instructions it is sent by the Evohome controller (i.e. % output). All BDR91s are identical but, for example, those configured to control Hot Water...

    I don't think that "short cycling" can be anything to do with the Evohome controls or TPI. If you have not configured a boiler relay or any zone valve, then Evohome is not applying TPI control to...

    Bear in mind that the cycle rate applies to zone valves, as well as to the boiler. If your valves are controlled by TPI, then they will open and shut as many times each hour as your cycle rate. I...

    Yes. I bought this Smappee Energy monitor in December 2017. It is no longer available. I am trusting that my Gas & Water Monitor, when it arrives, will connect to the legacy Energy Monitor.

    I've had the same problem, of the Loop gas monitor being discontinued. I have just ordered a Smappee gas monitor. Although Smappee is more geared up for professional installers, if you have the...

    I am not a member of the beta team either, but I noticed yesterday that my system has been modified. I spotted the icon for the hot water cylinder has changed, such that it looks different while it...

    It's an age thing, nothing to do with geography. In the 'old days' all the wiring for central heating systems was at mains voltage. Like DorrisMancer, my thermostats were all wired with three core...

    Just to break the silence.......

    I have found exactly the same as you. I have a CC dashboard but can see no way to include the hot water from Evohome on that. Just letting you know that you are...

    Radiators should be plumbed in parallel, not in series. Like this:

    It does sound as though the Lyric is working OK. What happens if you replace the jumper between Lr and Ls on your boiler (ST8)? The boiler should be fooled into thinking heat is being demanded. ...

    The Ns terminal on the ST8 block is only there for the old-fashioned mechanical thermostats, which take their power supply from the boiler. Their connections would be a live from the boiler (Ls), a...

    Referring to the manual again, you should have a permanent power supply (live, neutral and earth) to the ST12 terminals in Fig. 11 (item 1). That is the only neutral that the boiler needs. Fig. 8...

    I think this is the manual for your boiler. In which case, yes, T1 and T2 on your diagram are Ls and Lr in Figure 13. Apologies. I had not appreciated that the 35CDi can be operated at 230V. I...

    Have you really connected the 230V supply into the T1 terminal on the boiler? I do not know about the 35Cdi boiler but my Worcester GB162 operates on 24V. I have a relay that closes the contacts...

    I have stuck with the 'one zone per floor' approach, controlled by Evohome, rather than universal HR92s because:
    (a) 32 HR92s would cost me about £1.5k, which I don't want to spend;
    (b) Several of...

    I have Evohome but I don't use HR92s, so my experience is not directly relevant to you. However, I do have a GB162 65kW boiler in a three storey Victorian house with 32 radiators. I have no...

    I can assure you (and "Evo Home Support") that there is frost protection, whether they call it that or not. The "Off" setting simply moves the setpoint to 5oC. It even applies the differential on...
