Nest Thermostat- Phaq-U

[ray1970]

I keep my house at 70 degrees year round.

I wish they they made a thermostat that could switch between heat/air conditioning automatically during the spring and fall months when we get those huge temperature swings between day and night. You know, kick the AC on during the day if the house gets above 70 and then kick the heat on at night if it drops below 70.

I install automation systems and have done a few Nest's at the request of clients.. No problems with them.. The issues I run into everyday are F'ing HVAC guys that can't manage to pull wire that is capable of future upgrades.. If their system requires 2 conductors to operate they pull a cable with two conductors and thats it.. I've asked them what they do if the wire gets cut and why they don't run a 3 or 4 conductor wire just in case.. They look at you like a deer in headlights.. I even run into HVAC guys that flat out tell me you can't run Heat and AC off the same Tstat.... I can go on and on about HVAC guys..

That said, if your system is wired wrong blame the guy that pulled the wire for being to cheap to spend $2 more on a cable with an extra conductor.

As for hydronic/in floor heat.. You shouldn't be changing the temps on those systems throughout the day, it will actually cost you more money to do that, they are meant to stay at a constant temperature to be most efficient.

There's always exceptions to every trade. Unfortunately most of the people in the HVAC realm are afraid of technology. First people were scared of two stage technology and high efficiency, now they're afraid of fully modulating integrated technology.

On a side note feel free to step off your high horse - you only do automation after all.

they do, Honeywell makes them and I have one for each system in my house. You just set it on auto, takes care of everything for you. Don't know the model off the top of my head.

I finally had to pull the thermostat last year off my mother's wall. It had a bimetal coil and a big mercury bulb switch. Talk about EMP proof ...

Replaced the original one at my Dad's house from 1950 last year when he had the furnace replaced. I'm pretty sure there was a little pterodactyl in there flipping switches...

I just bought some 18-8 wire today for a house with only heat... Its usually the installers that don't give a shit..

Do service for 12 years and you'll learn how to do things right the first time.
