Or even better, if your boiler supports OpenTherm, use that!
Hello folks, hopefully the below diagram displays correctly.

I would like to use the grey and orange wires on a Honeywell V4043H zone valve to send a simulated NTC signal to my ATAG i24s...
The open by default, motor to close valve.
Sorry for reviving an ancient thread! @HenGus, almost three years down the track, are you happy you went with OpenTherm on the ATAG? I'm about to get an iS 24 installed, and having the option to get...
Yeah, you're absolutely right, and I'm going to re-plan all my room schedules because the house has felt colder since I did a major schedule fiddle about 18 months ago.
The issue I have is that the unused rooms have windows (which let light in), so if I close the doors it makes the interior of the house significantly gloomier. Hence all of our (used and unusued)...
Rechargeables (even good ones like Enerloops) have less capacity than a good quality Alkaline battery. Given how little Alkalines last (it seems like some rooms last me only around a year), I've...
I have no knowledge of how HR92s work, but from a purely common sense point of view, how could you design a system that "learns" without any feedback? "Assuming" how a particular radiator valve works...
Surely there has to be a fault? The HR92 has no idea what the valve is doing "under the bonnet", it just knows that anti-clockwise = more heat, and clockwise = less heat. If it's demanding heat while...
Ooh the washers idea might be really good... I await your results DBMandrake.
I adjusted all the little black plastic hex thingies so that screwing on the HR92 base just barely touches the pin without pushing it in. I wouldn't call those black plastic hex thingies a...
Surely EvoHome will learn the behaviour of the new boiler and adjust accordingly?
Hi @paulockenden, now you've had this setup (Eco RF + OpenTherm) for a few months, how is it going? Are you happy with it?
Cheers,

This is where I'd start. You need to remove Domoticz and just let Evohome be Evohome all by itself.
That stuff really works! I rented in a place with wooden windows (with double glazing), but the windows were quite warped and a few had serious drafts. That cling film stuff made a *massive*...
You can't put the controller somewhere more central?
They operate in tandem. I have two radiators in the master bedroom, and you can hear them, always together. If they were operating independently you would hear one or the other, but they *always* go...
Maybe reboot the HR92 by briefly opening the battery top?
I've just checked, and I have one overshoot (11 degrees over) in the past 7 days, and a couple of days ago when I checked I had a couple of errors from the hot water sensor (haven't correlated them,...
My warning would be that you are introducing *significant* additional complexity which will lead to numerous possible outcomes: greater chance of failure, higher cost of maintenance, harder to find...
How many months since this new firmware was announced, and my latest generation controller still hasn't received the update?
Would be keen to understand your thought process on this. I'm neither a plumber nor a heating expert, but just looking at the innards of various brands of boiler, the Intergas looks the simplest and...
Really keen to hear what you decide on, Paul. I'm very far from convinced that Opentherm is worth all the extra hassle and restrictions on model choice.
You can finger tighten the little black circle that surrounds the pin on the Valencia. This will lower the pin (you are effectively reducing how far it opens / sticks up). I've done this on mine so...
Oh I'm not expecting the fuel savings to pay for the cost of the replacement! But it would be nice if some of the cost was offset. My main concern with a ten year-old boiler is that it will fail at...
