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.
