I used to have my hot water storage just heat for an hour or so every night and morning, until someone questioned why you would ever want your system set so that you could feasibly run out of hot...

Lots of things are currently totally unavailable.
Semiconductors used in some of my own designs have lead times of up to 12 months, meaning having to redesign using alternative components. ATMega...

They could advertise them at £10 each, but if they don't have any stock then it's moot. Amazon always seem to continue to advertise products that are out of stock or even permanently no longer...

HR92 seem to bit around the £100 each now, with stocks limited according to Evohome shop, JTM plumbing etc. Yikes!

Did you move the little plastic locking slider to the closed position so that it thinks it's on a radiator?

You can do this with Shelly Dimmer 2 modules: https://shellystore.co.uk/product/shelly-dimmer-2/
You can use your existing conventional light switches wired to the Dimmer 2 and configured in 'edge...

I've had this happen before, and I came to the conclusion it was related to one of the HR92s rebooting itself and then when it came back on it defaults to 20 degrees. I don't know why it didn't...

Yes it does seem a bit odd that you are getting the issue with Valencias. In our last place when I first installed an Evohome system I installed Valencia bodies and they worked perfectly, so I wonder...

I had the same problem with some 'decorative' type TRV bodies, you could hear a little bit of restriction when the HR92 was fully open.
The easiest solution I decided was to simply remove the steel...

Not quite the same situation, but I have some TRV bodies that do not open 100% when the HR92 adapter is screwed on and the black wheel fully unscrewed, as the pin in the TRV is slightly too long -...

It’s supposed to beep when it loses power, isn’t it? Mine always has done, from new.

Thanks all, @dbmandrake actually it was hardly any work at all, I'd say it took about 30 mins not including drying time of course! I actually did just one first as a test to see what the finish was...

Hi all I'm not the OP but moved into a new place with cast iron rads in Anthracite Grey so decided to paint my HR92 as they didn't look too great in bright white against the grey. The rads are powder...

I had a couple of 'ghost' zones appear when my controller was on old firmware and I tried to add new zones and aborted partway through the process (when I discovered the electric heat zone type...

Not sure about that, I bought one two weeks ago and the firmware didn't have Electric Heating zone type support, had to contact support and they pushed the latest update through to me.

I've been looking into this recently, along the same lines as the brief in the OP. It looks like the Lutron RA2 Select would satisfy all of those requirements, certainly if you can get access to the...

That's the PlastiDip I was referring to. EDIT: or maybe vinyl wrap? I agree with DBMandrake that a silicon type cover is going to start having some noticeable insulation properties, so an external...

Shame there's not some sort of silicone cover available that could be fitted over the units. I wonder if PlastiDip https://www.plastidip.co.uk/ could be a good option, you can just peel it off again...

Thanks, I did briefly look at the practicality of opening one to change the orientation of the screen and then soon gave up when it seemed like I wouldn't be able to easily do it without breaking...

I very much doubt a layer of paint will have any significant insulation properties.

Why would the internal temperature sensor no longer be suitable? The colour of the casing only matters in terms of solar gain surely, which I would think would be insignificant compared to the...

I have been wondering the same thing as although I've recently fitted an Evohome system with HR92 to all radiators which is fine, but we will soon be moving to a period property with cast iron rads...

Thanks, sounds like there are a few of us thinking the same.
I can't see that the limit is due to technical reasons such as RF channels and device IDs etc, as there is the ability to bind more...

Ah yes I do recall seeing that in the manual now you mention it. Ah well, I'll forget any idea of future firmware updates then!

Nobody else finding that the maximum of 12 zones is limiting, if...

That depends, maybe the HR92 is now more wrong?! I think you need a third device to decide which one is measuring incorrectly :-)
