>10V is possible ...
ah, good ...
>better control system ...
yes, I would say, even regardless of means of heating, because radiant environment is a key thing for individual comfort ...

air quality being the other ...
still, the devil will be in the detail, as always !Last edited by chris_j_hunter; 12 March 2009, 10:03 PM.

Interesting. I've known this concept used for external application where the sun beating down on you can make a big difference to perceived temperature level inspite of 'temperature in the shade', but I wonder how much qualitative value you get inside a home. Anyone seen any such research documents? Obviously another important factor is relative humidity and - I personally find - even small airflow (draughts :-) ).
Yes the QAI can be supplied to range 0-10V, though I note that the list above shows a number of NTC thermistor options which can I suppose be connected in as part of a potential divider with suitable linearising mapping being done in Cortex but resolution will be relatively low as compared to something like a DTS or THS.

am convinced radiant temperature is a key factor, as much as air quality (temperature, humidity, velocity, flow pattern, odours, dust, etc) ... warm air & cold walls miserable, warm walls & fresh air much better ... etc, etc ... for evidence see, eg:
and references therein !!
we're certainly trying to pay attention to all the factors (new build, so half a chance) and will be including black bulb, and the rest, 'though need to decide which sensor option - & be sure of sufficient resolution !Last edited by chris_j_hunter; 16 March 2009, 01:07 AM.
