I learned more in the comments than I did in the video. There are so many variables in this kind of installation, I quess that this shows us a basic install. Probably the biggest issue is whether you and your wife like the same temperature not so much if you can use your phone to set the stat!

Glad the setup was so easy! Turn the power on and the app will install itself and pair to the thermostat!

A good practice is to snip the bare wire shorter so there's non visible once connected to the faceplate. There looked to be at least 5-10mm bare wire shown at 5.58 and these could easily connect and cause a short or even a fire when pushing the housing back into position. This is why the wire has the plastic insulation in the first place.

While it's good for an upgrade, I kinda like the idea of, in a new build or "bare stud remodel" such as what's normally shown on This Old House, that "mother box", acting as the "central control unit" of the HVAC System while the thermostat(s) can be simpler. Basically, in a server-client model, that "mother box" is the "server", while the various thermostats and/or temp sensors are the "clients". Also, if you ever wanted/needed to upgrade it, swapping out the (one) "mother box" seems easier than swapping however many "thermostat controls". Don't get me wrong, I would still want to run the wires to each thermostat, but this still seems like a better setup, overall.

Or just use any thermostat that can have external indoor probe and put just probe to interior by those two wires.

This solution is about as costly as having a professional run new wiring, in my area the estimates were $350 and up. So I went to Home Depot and bought 50 feet of 18/5 thermostat wire for $21 and fished it through the wall myself by tying it to the existing 2 wire (R and W) that the old thermostat used. I've never done it but with a little patience it's not difficult. Every connection is labelled on both the furnace and the thermostat (I need C, R and W and didn't have a C at all). You just plug the wires accordingly. Now I have both a sleek new Honeywell smart-thermostat and future proof wiring to the furnace without all the extra or a giant bill for an HVAC guy.

@greg_216

Your approach is probably going to work for most folks. Furnaces tend to be centrally located and thermostats tend to be centrally located, so it's usually not a complicated run from one to the other. However, some folks have houses that are labyrinthian and trying to pull new wires after old might simply be impossible. Another alternative is to just move the thermostat someplace where it can be more easily connected to the furnace and then use a remote sensor to get a temperature reading that's more representative of the centroid of the house. In this case, the sensor could have gone where the thermostat is (only needs two wires), and the thermostat could have gone down in the basement.

@@greg_216 Agreed, I knew it would work because it had already been done, I could trace the wire and see it was a straight shot. Had I not been able to run the wire up the wall I would have simply gotten a thermostat that communicates to sensors and moved it to a basement wall. I might replace this thermostat now because it doesn't support sensors and there is a slight, but noticeable temperature difference between upstairs and down. At any rate, it would be better to do the labor yourself than to pay a HVAC guy to do it because they will charge a pretty penny for what really is a moderately difficult, DIY job.

That's the *right* way to do it in the grand scheme of things. It always amazes me the lengths builders will go to in order to save a bit of money while at the same time making simple tasks SO much harder - they could probably have run 4 or 5 wire, at a cost of pennies per foot (at the time) and just left all the spare wires in the wall for future proofing. I had a similar situation upgrading my tstats a couple years ago, but the builder had run 7 wire to the second floor but only 4 wire to the first floor. So, getting a C wire to the second floor was easy (just connect to C terminal) but getting one to the first floor required another run of cable. In my new place, it seems I will have to run new cabling to the second floor as it's 2 wire only, and I don't want to be tied to one of these esoteric tstats, and I also don't want "add a wire" transformers looking ugly all over the place. It's not that bad though, as I had also planned on running a central conduit from the attic to the basement to facilitate ethernet wiring; a few small TC wires won't take up much space.

My guess ps the Transformer supplying the power is too small when it calls for heat the relay coil is asking for more amps than the transformer can supply so your voltage drops and falls below the required voltage to power your T5 thermostat thus causing the unit to reboot. ( when power is first applied to a relay coil it briefly acts as a short.)

My existing thermostat only has red, blue, and white connected. The yellow and green wires are there, but not connected to the existing thermostat. Should I connect these to my amazon smart thermostat?

I thought Richard was a plumber not a sparky??? In the US, is he allowed to do sparky work as well?

what happened to the nest one?? are you claiming that you can only do this with the tekmar??
