[Greenbuilding] How to not short-circuit passive solar/in-floor hydronics

[Drew A. Gillett, P.E.]

a simpler way is to put the tstat in the same sun as the floor slab contrary 
to standard tstat location advice.. it would slow things down as soon as the 
sun hits it and the slab.   perhaps you want a little delay.  locate it 
where the sun hits it an hour later than the slab.
