Re Thermostats-Choose a manufacturer that supplies online schematics etc
to save later heartache. I just purchased the Honeywill 7500 ($100) for
the used heat pump I just installed. Unforturneately, the owners guide
omits pages 21 to 45, apparently the "configure installer setup".
After a call to Honewell 800-no one available no 24hr per message,
(Saturday) and reviewing their web site, no info available for
specific wiring questions. I forgot that I had another Honeywell on
the shelf and had previously tried to locate online info for wiring
with no success. I will not purchase another Honewell until customer
support will release enough info for the do it yourself group to
fullfill their ambitions.
Note: I am installing a new system (used) and therefore am not able to
label the wires removed from the old thermostat which generally makes
life easier if doing like for like! Be aware that you must read the
thermostat package labels to determine the ultimate use-may work for a
furnace, strips etc but not a heat pump or even differentiate a single
state and two stage heat pump. Often reading the wiring schematic
inside the door of the heating unit(with power off) one can determine
the correct wiring in combo with the thermostat owners guide. The
learning curve is considerable but I find the reward to be significant
knowing that with a little (or a lot) of effort we can accomplish
anything! Note: try www.askmehelpdesk.com.
Good luck and thanks to those with the knowledge they share to help
others to be successfull in their endeavors!

So suddenly everybodies unit only has 2 wires?

I don't think so Tim!

BTW, you would be suprized at the people that can't program a VCR or
Stat,
let alone hook either of them up correctly!-

Same thing if you have more wires. You follow the instructions. Tens
of
thousands of thermostats, many with multiple wires, are successfully
changed
each year by plain old homeowners. I'm sure a few do screw up, but to
make
a blanket statement that everyone should call a pro is plain silly.
