Changing a two wire Thermostat to a 5 wire or just 3?
 

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!

You might look behind the T-stat downstairs, It may also have the
wires you need.

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.

+1 And the latter type, ie that use wires to the furnace, connect
to the internet via wifi, are the most common type.

Hi,

2 wire means it only controls base board heating? It sounds like this

one is heat only or cool only 'stat. 5 wires are for both heat and cool

control. WiFi 'stat needs to be connected to a router for remote access.

If that is what you have in mind look at also Ecobee. I installed Ecobee

at my daughter's 2nd home and it already did it's worth

this winter when furnace quit(burnt HSI fault), it sent alarm to my

daughter's iphone preventing possible freezing in the house.

Sounds like April fools day. If he has heat and AC, then how does
the existing thermostat only have 2 wires? But if it's somehow true
and it's too hard to run wires, I seem to recall seeing a wire
expansion widget, where you put a multiplexer at the furnace and
one at the thermostat and it turned 2 or 3 wires into 6 or whatever.

If you don't get any answers in here, you can try a web site called "Heating Help" that has a DIY Q&A forum just like this one, but is populated with heating contractors.
