Not that I am invested in the "Nest", but perhaps I could "solve" my next Homeowner install problem.

In the mean time, I am telling them that their new T-stat is not compatible with their system.

well im going with the ecobee was not really impressed with nest reviews

I would go with the Ecobee that is a a good stat with remote control

If your looking for alternative then look at Entouch with Energy monitoring

I installed one in my House and sell these to many school systems

Here my link

ECOBEE DOES THE SAME AS NEST AT A LESSER COST. I WOULD GO WITH ECOBEE

Yeah isolation relay.

Yep a easy fix for that!

Sold them a Honeywell with the red link t-stats instead, and they returned the Nest.

There is a fix to that. It will happen in cooling also

Got to love the power stealing technology Nest uses...

also is the Prestige available with an ability to add on a few room sensors ? i may need to put stat in one side of home near large living area and master bedroom but the home is oddly shaped and part of home is sort of isolated from main part of house and its going to be hard to keep these temps comfortable with it being so far from Tstat.. so maybe like an option to add a room sensor or two that works with Tstat as to take those rooms into account before shutting down??

so i am very fond of the HW 8000 series especially ease of set up and installation.. is the prestige still have this user friendly feel? I realize there is a little more involved in initial set up but is it still close to the straight forward feel of the 8000s?

TIA

Good luck! Give the nest a few weeks for the data to build up on the web site that is when it gets fun for a Tech to play with.

OK I am taking a NEST for a test run next week then a ecobee the next week. At first look I really like the way the Nest looks but the Ecobee is really starting to grow on me.

I like the Nest and Prestige IAQ with a redlink gateway.

The Nest has very good home web page that brakes down your energy usage and easy to control home comfort programing. But not very good if you set the away temp a long ways from your comfort temp. It's a self learning stat and has a motion sensor that helps you set your programing. Very cool stat if you play with one!

The Prestige IAQ has alot of options and is very easy to set up and will work with all types of systems and IAQ. It is pricey but for all the options worth it.

I have. Ive been signed up for that for a few months and havent had the first call.

Maybe you need to charge more for your time. That's where you are adding value.

And if they don't buy it from you, they are their own warranty station.

The Nest stat is not something to take lightly or thumb your noise at...it was well developed and being well marketed. You need to look at it as an opportunity to either help your customer get it installed or install it for a potential new customer.

I have heard of some companies offering a deal if done with a maintenance check-up. You have to think like the Nest folks do...outside the box!
