Hi All,

I have been looking at heating controls for time now and I have been told about heat miser today.

Has anyone interfaced comfort with the Heat Miser wifi thermostat?

Best Regards

Lee

We will be working on a dedicated Heatmiser UCM as the next project

Do you have any further details

Will it work with v2 stats and Heatmiser UH1 wiring center.

Will it be a new UCM

What cables will i need from comfort to UH1

Will control be available via KT03, iPhone and Android app

Thanks

The engineers are still studying the requirements. Perhaps you can give some feedback

Do you want compatrtibility with v2? Are they only selling V3 now or v2 as well as v3

Is is necessary for Comfort to know about the UH1 wiring centre?

It will be a dedicated UCM and all comfort user interfaces, iphone, KT03 etc will be able to control and monitor the heatmiser products

Yes i would need v2 compatibility.

I believe they no longer sell v2 equipment only v3.

I guess Comfort will need to know about the UH1 as that is were the coms port is.

I can beta test it if you need tester

I have UH1 wiring center with 5*PRT-N v2, 1*PRT-EN v2, 1*PRTHW-N

V2 and v3 protocols are completely different so the same UCM would not support both. We can justify developing support for v3 but unfortunately not for v2 which is no longer produced by the manufacturer

The interface with by by RS485 or wifi so it would not be related to UH1

Maybe someone could explain what Heat Miser is as I looked at their website and still in the dark.

Are they doing underfloor heating only and/or central heating systems?

Their website has lots of pretty boxes but little text and no wiring/solutions guides.

ie could I replace my aging Smartfit solution with this in the UK?

...or are they as wikipedia suggests a 90's US Rock Band! :0)

Hi slychiu

Thanks for getting back i thought that would be the case v3 support only.

I don't mind upgrading the stats to v3 if comfort UCM provides full control.

Will you be supporting the 12v Network stats PRT-N, PRTHW-N, PRT-EN if so then these all connect back to the UH1

The UH1 also has a RS485 connections. All the 12v Network stats connect to the UH1 and 1 pair of the cat5 cable is for comms. I believe the UH1 is just acting as a junction box for the comms.

To juwi_uk

Heatmiser do a range of heating controls either standard 230v stats, 230v stats with WiFi or 12v network stats.

I currently have 12v network stats, running underfloor hearting on ground floor, radiators upstairs, and hot water. They also do central control for 12v which i dont have at the moment, using central touchpad or NetMonitor

They have a lot of documentation on their site under support > manuals

Thanks

Is there a way to find out installers/plumbers that can retrofit this solution in the UK. I'm in Berkshire and could do with someone quoting for this at some stage. Maybe I need to wait until I know what Comfort is going to support. I can also then build in some "sexy" support into my ComfortClient app.

Hey Chiu, advance warning for an evaluation UCM/HM! ; 0)

Yes we wll support al the models. The connection by RS485 is to all thermostats in parallel so the UH1 is probably the best place to connect the UCM. However the UCM will not "need" the UH1 as it seems to be a place to do the connections only

Hi slychiu

Yep UH1 will just be a connection point to UCM.

juwi_uk

My plumbers was lost when i told him my stats are wired in Cat5, in the end me and my electrician wired it all up. It should be fairly easy to retrofit if you have standard s-plan heating wiring and you can get cat5 run to the stats. What is your setup at the moment.

Yes that's the trouble with heating IMHO, installers have their own preferred setup and aren't usually willing to install what the customer actually wants.

I have a current (I'd say simple) s-plan Honeywell Smartfit setup at the moment connected to the old UCM/Smartfit. I don't dislike it but again I had to go with what the boiler installer was fitting at the time.

My house is completely cat5 wired with gigabit Ethernet switching and I run phones over cat5 too so know your pain. Even the BT guy goes white when he see's my comms centre!!

My UCM/Smartfit is currently next to the Smartfit base unit in my airing cupboard (next to hot water cylinder) so should be easy to upgrade when the time comes. It's is a small UCM enclosure I originally sourced from the old Comfort reseller in the UK (who's name shall not be mentioned...) and still hoping that one day Cytech (hint hint) will develop one of these single UCM enclosures for remote UCM siting!

Julian

Update: actually I have Y-Plan (tri-valve for heating/water) so I'd need pipework changed too and thus a plumber/installer; doh why is nothing ever straightforward..!

Ah I can see now by the way that I was on the wrong heatmiser site. Was on the heatmisershop site.

I have a v2 system. I could upgrade a component to support this, but not the entire system.

Y-Plan should work fine as well, have a look at electrical install manual from Nu-Heat

I have exactly the same set up as Dils.

UH1 connected to eight touchscreen V3 thermostats, mix of underfloor and radiators. Haven't 'invested' in the Heatmiser control gear, so the system is standalone currently, but would be interested in connecting it to my Comfort system.

Echo those sentiments about the plumber / electrician's face when I told them the thermostats were wired in Cat5!

Happy to be involved in any testing you need too.

Henley
