[Hai-users] Multiple Thermostats per zone

[Joseph K. Vossen]

my understanding (and I am NOT a HVAC expert) is that you can do this but 
they have to be in a master/slave relationship.  The unit is wired to the 
master tstat and the other tstat (the slave) is wired to the master.

what you really should do, IMHO, is zone your HVAC system.  I have 3 units, 
each one has 3 zones for a total of 9 separate heating/cooling zones, each 
with their own tstat.  If you go this route, you will need a zone controller 
(at the unit which the tstats connect to and also runs the damper motors) a 
damper motor for each zone (to open/close the duct(s) feeding the room(s)) 
and a pressure relief value.  This is pretty straight-forward and any HVAC 
installation company worth their salt knows how to do this.  Once the system 
is in place and tuned, it works very well.
