    I don't have an T87RF but for those that do it could be simulated by resting the sensor above a hot radiator - should be easy to get the reading to 32 degrees or above that way. Anyone game to try to...

    For the record I still get "comms errors" from the hot water sensor. Nothing I do will fix it. I have just learnt to live with it because I have better things to do with my time.

    I had no luck with the variable speed modes on my Alpha 2 - same as you, runs too slowly and the boiler overheats, so I run it in fixed speed 1 or 2.

    I think the variable speed modes have a...

    It wont be a potentiometer as you can turn it infinitely in either direction.

    From memory it's an infrared optical chopper system - very commonly used in digital knobs which can turn infinitely.

    I really don't see the attraction of using NiMH in the HR92. The only real benefit is from a waste reduction perspective, in every other way they're vastly inferior in this application.

    Aside from...

    I've been using GP Ultra or Varta Alkaline's in mine for over 5 years - never had any leak or even show any signs of leaking.

    Sounds like a plan. Before I had Evohome my bypass radiator was the hall way so I had to add a TRV valve body to that one to get HR92's on all radiators, and also added an automatic bypass valve.

    Why are you still using the old room stat to control the boiler instead of Evohome?

    Evohome's algorithms are designed to control heat output of radiators by controlling both the individual water...

    Indeed. If load scaling is on "Normal" try changing it to "Partial", or even off.

    "Usual practice" perhaps, but that assumes you are trying to adjust the balancing of the radiators to produce a certain temperature differential across each radiator. This is indeed the traditional...

    Yes this is exactly what happened to me when I tried to use the variable speed modes on my pump - all three variable modes were completely useless on my system because the pump would slow right down...

    Your point about reflective metallic surfaces is correct, however most modern radiators are painted and therefore don't have reflective metallic surfaces... Paint makes a good black body radiator and...

    You're right - depending on the orientation of the valve. An old unidirectional valve should always be fitted so that the flow follows the direction of the arrow. This could be on the flow or return...

    Are there any long runs of pipe with no mechanical support, long enough to allow a resonance to occur? If so perhaps some additional support brackets would help.

    Can't speak for the HCF82 but the HR92 doesn't use a discrete bead of any sort, it uses a temperature measurement chip with a built in sensor.
