I have a home built in 2006. It has baseboard heating and Air Condition via blown airCeiling Vents.
The upstairs zone contains a 5 wire thermostat while the downstairs zone
is only two wires? The AC unit is in the attic. Is it possible to run a
5 wire or 3 wire to the thermostat on the first floor? I am looking to
add a Honeywell wifi thermostat.

Thanks!

I think this may be an April Fool

But to answer it:
Of course it's possible to run wire. Why wouldn't it be? Just run the
wire..... Your biggest problem is how many walls will need to be ripped
apart. Another option would be to run it thru a conduit on the exterior
of the house and eliminate ripping walls apart.

But since you said WIFI thermostat, why would you need wire? It's
wireless (I guess, since I dont know anything about WIFI thermostats, in
fact I didn't even know they exist).

Happy April Fools Day!

Hi,
Wireless and WiFi implies two different thing. Wireless one eliminates
wires between 'stat and furnace but control module is located near the
furnace and between furnace logic board and control module wires are run
just like wired 'stat. WiFi 'stat is wired but it connects to network
usually via home WiFi router so you can communicate 2 ways between you
and 'stat using smart phone. Just like home surveillance IP network cameras.
