Brett: I totally agree with you about the
set back thermostat. The only other X10
thermostat that I know of is the TXB16 by
Residential Control Systems (RCS).
Automated Outlet (
www.automatedoutlet.com)
sells it for $193.99.
The TXB16 is a fully functional thermostat
and uses X10 commands to change the set
point temperature and mode of the
Thermostat. It seems really quite
sophisticated (it can take an average of
multiple temperature sensors for example)
but I have never used it though.
I hope this helps.
