Comfort is able to talk to heatmiser one way using the UCM/Universal with AUX485 interface.
However I do not know what is the UDS100 you used

The UDS100 is a serial device server, allowing you to easily convert between RS485 and ethernet : UDS100 Description

Perhaps one for the heatmiser Forum?

A good suggestion.

The reason I posted here was that there seemed to be a number of people discussing both the RS485 interface as well as the Heatmiser protocol.

I had some success last night ; I got the Thermostat to respond. I tried a different command and this time received a response. The problem appears to be a buffer effect in the TCP connection. I will investigate further but believe this to be the cause of my problem. The upside is that if it is a software problem it should be easy to solve!

Hey northview,

I ended up paying someone to build me a page in PHP that talks to a app on the server written in C# that communicates to the device and allows me remote access. I did talk to Heatmiser support with a few problems we had and yours maybe the same, see below.

Good luck, im happy to share my code with you. Just PM me.

"the thermostat neeeds a communications number in order to access the network
the default setting is 00 which means no network.
the range is 01 to 32 and each thermostat must have a unique number
this number is set in the feature menu see the optional settings at the back of the booklet for the details.
Feature 6 is the communications number if it is set to 00 it wont respond to your code."

(copied from Heatmiser WiFi thread)

In discussions with Cytech it would appear they are agreeable to considering doing the Heatmiser Integration using the UUCM / RS485 (soon I think).

For those of you that don't know them the Heatmiser products are very prevalent in the UK and elsewhere and are OEM by lots of other companies. They come bundled with underfloor heating kits etc. with other suppliers name on.

At the simplest level you can take say a 12v (touchscreen) themostat and wire it into a Comfort Zone and 12v supply.  You then programme what you require e.g. turn on a discrete relay (or Cbus, Dynalite etc.) to control the boiler / electric underfloor / fan / blinds etc.

Once you have multiple zones etc. then it becomes more complex in providing overall control and that is where Heatmiser provide their Touchscreen to 'co-ordinate' and make configuring / adjusting easier. Where you have a Comfort system that might be a preferable route to take as you may not want additional devices and may want things like heating set back on Arm.

Although I have no looked closely it would appear my Vaillant boiler has both low voltage control connections as well as mains level. The latter being for the traditional time clock  / thermostat configurations. The manual actually states the low voltage connections are not for use in the UK but I have not researched this further.

In my configuration I have a kitchen / bathroom extension with underfloor heating and since that may be heated say in the morning (before work) I would typically have a single channel stat, possibly with probe and then elsewhere another dual zone (rads & hot water) for the rest of the house with pump, some motorised valves and TRVs. Valves mean an occasionally used bedroom could be generally isolated and then turned on from (say) a wall switch (Scene Control Switch; Cbus etc.) Once 'On' it can be part of any overall control e.g setback on Arm.

Considering involving Comfort in heating controls is something for anyone to consider as it may improve control  / save cost etc.  My experience is that it can work well but perhaps with some for of override in case of rare problems.  In the case above the individual stats could be configured to continue operation without Comfort present.  In any event a couple of manual switches could provide continuous operation of heating and hot water.

Where Comfort is integrated with Heatmiser at the network level it is possible for the KT03 touchscreen to provide a variety of controls.

As ultimately the objective for Cytech would be to sell more product it would be good for as many people to feedback their interest etc. here, so Cytech can gauge the benefits.

No RS485 control directly into the Heatmiser i/f ? As long as there is no reliance on the KT03 - that has to be one of the worst products I have ever had the displeasure of coming across. A KP04 can't come soon enough I'm afraid.

Presume you mean a KT04 then as otherwise you must have missed the KP04 a few years back during its evolutionary rise to KP06dom! ;0)

Well it looks like the Heatmiser integration will be proceeding soon see: Heatmiser I would agree that integration should not mandate a KT03 although I have personally found them good to use at their price point.  e.g. when you layer keypad; blind/window control; door entry and heating control functionality etc. you are doing quite a lot for the £ I would think a 'KT04' slightly larger with colour would be good and (composite) video in for door / gate camera. My documented use of Comfort and Heating (with KT03 without Heatmiser) should finally be posted in the next 2 -3 weeks.

I'm after a Heatmiser Touchpad v2, also badged as a JG Touchpad (they of Speedfit plumbing fame). It looks like this


If anyone has one they'd like to sell, or has seen one somewhere, I'd love to hear from you. Thanks!

I am also in need of the same touchpad on the basis the LCD has just failed.

I am at a loss as the v2 protocol is no longer supported by anyone. Alternative products therefore do not work. Does anyone know whether it is possible to get a solution to convert the v2 protocol to the v3 protocol?

Any ideas to provide a solution to allow me to control the 32 thermostats I have installed centrally would be most welcome?

Best wishes
