Replacement Central Heating Controller (wired)

RomfordNavy

Can anyone suggest a decent quality Wired Central Heating Controller/Thermostat to replace a Honeywell CM907? The screen display has all but disappeared yet again, this is the third Honeywell controller which has failed.

This is for Gas Central heating and hot water Combi boiler.


Thanks,

If it’s a combi there are a multitude of programmers...out of interest why not wireless?
And what make/model of boiler?

But have a look at the Honeywell Lyric T6

At a guess, I'd say price

When my vintage Drayton timer gave up the ghost, I replaced it with a cheap Flomasta from Screwfix. Did the job, but I now want something with finer control over temperature & time as well as easier to program.

You can pick up wireless controllers for cheap these days. You can of course get your Nest stats and things like that. You can also get Parts Center own brand wireless programmable thermostat which is £58 plus vat.
It’s made my Honeywell and is basically a CM927 but without the price. Fitted loads.

Boiler is Vaillant EcoTEC Pro.

Trying to avoid any more wireless signals floating about than necessary for health reasons.

Honeywell Lyric T6 looked good until I found that it had Wi-Fi built-in.

The downside of wireless (for me anyway) is that they use Bluetooth or similar and may or may not be encrypted. Most likely using a proprietary protocol to boot. If they use wifi, then an app is going to be needed to set the wifi name & password. Then if the app allows you to turn on/off the heating from elsewhere (or connects to Alexa/Siri) you are subject to the whims of the app provider along with any security holes.

I'll stick with hard wired sensors and open source software.

Normal programmable wireless room stats don't use WiFi or Bluetooth they use radio waves, you are thinking about smart stats like nest etc,

OP there are tons of radio waves all around you all day every day to say you don't want a RF stat because you don't want anymore around you is kinda crazy

And what do you think wifi & bluetooth use ?
Bluetooth uses 2.45GHz and wifi uses either 2.4GHz or 5GHz (although there are several other frequencies that could be used). For wireless home heating systems, 2.4GHz (Zigbee) and 868MHz (Z-Wave) are often used. Ofcom designate several other frequency bands for use with industrial, scientific, and medical use (this also covers domestic), but the ones mentioned above are the most common.

Bluetooth, wifi, Zigbee, et al, are just the base protocols that utilise the radio waves.

Ok I stand corrected, thank you for the info

Do Hive make a 'Wired' controller which is a stand-alone unit and doesn't need any sort of additional hub or receiver?
