    On the Intergas x-plan wiring diagram, there is a cylinder ntc sensor. Does anyone know what part this plays when there is also a cylinder sensor for Evohome?

    So the TPI issue is probably sufficient to send me down the x-plan route. Out of interest, does the evohome opentherm implementation allow different flow temperatures for DHW and CH? (I believe this...

    Is that true with x-plan? I thought in that case the CH loop opened when the DHW loop was closed. ie just one BDR91 on the DHW loop.

    Evohome, DHW priority and x-plan

    I'm looking at replacing my boiler, probably with Intergas. I already have EvoHome complete with DHW control.

    The question I have is around DHW priority. There are a number of articles that...

    My only thought is that the local temperature around the immersion is much higher than where you are measuring. As the heat dissipates to the rest of the cylinder so the immersion comes back on.

    Completely understand where you are coming from. Depending upon what they are doing, one option is to use the hot water override (assuming you have a DHW tank and it is not up to temperature).

    Exactly the same issue with my DTS92 this morning. Blank display (low battery had been on). A few anomalies, such as dhw temp not updating. Replaced batteries and all back to normal

    Not an expert, but I suspect that you are going to have to have a HR91 (or 92) on at least one of those radiators. The controller can act as the sensor, but it is expecting to control a TRV. I'm not...

    My memory may be failing me, but I'm sure there was something about having to configure stored hot water before anything else. I don't know if that is the cause of your problem.
