I currently have a Climatouch CT0-7TC-21 thermostat. It is a 2 heat , 1 cool thermostat. I use this to run my Earthlinked Geo. I need to replace it because it has failed. I do like the programmable function that it provided with the 2nd stage (electric heat). You could program as to when the 2nd stage should come on after so many minutes of the 1st stage (Heat pump) running. Climatouch is no longer in business and I can not find this stat. Does anyone reccommend a stat with similar functionality for a heat pump?

I like the Ecobee's not only because of the variety of set up features, but you can monitor your systems performance.
Honeywell makes an economy stat I think the focus pro 2000 with 2 stage heat (that will be under $50) that you can set the droop (temperature difference between 1st and second stage activation).

I just received a Nest WiFi thermostat as a gift. Live in Minnesota, plan to spend some of winter in south and want to be able to monitor my house while away. I have Econar Geo system (year 5) that has experienced compressor faults in all but one winter where I had to trip breaker to the unit to reset usually multiple times a winter and had installer out each year to troubleshoot and fix. Does anyone see any problems with installing this type of thermostat on this geothermal system? I feel I have to be able to monitor it in order to keep the installer honest and my house from a freeze disaster.

I'm not a student of the "Nest", but if it has enough stages it may work. Incidently when you get unit lockouts, you can often reset it by turnign the thermostat (instead of the breaker) off and then back on. I sell Ecobee thermostats with my heat pumps and have remotely restarted equipment. I also have the equipment email me for a variety of things including falling temps in spite of a call for heat or greater than X hours of auxiliary use in the last 24 hours.

That is exactly the type of info that I am hoping to have provided. Nothing worse than something going haywire when you are 1000 mile away. I will try resetting the unit by using the thermostat if or when it should lockout again. I like options that don't include having to call a neighbor to to reset things. Thanks for your reply.

I was a beta tester for Ecobee's new product offering.  I do not recommend it.  They rushed it to production, with many problems still to solve.  And they have serious support staff coverage challenges.

Further, in my extensive testing, I determined Ecobee's new product offering is definitely clearly *** not *** compatible with WaterFurnaces Intellizone.  Further, they (Ecobee) decided it wasn't something to try to fix.

On the other hand, the non-new product offering from Ecobee is excellent.  And I recommend their use.  We use the commercial version of their thermostats.  Expecially the Si version (the version that doesn't require a touch screen).

Look at the Si version.  I think this is what Joe uses.  They're solid, and, provide a lot of remote capability like what Joe talks about.

Best regards,

Bill

Bill I was using the EBSTAT2. I think they are headed out of production however and I just installed my first 3 and have some complaints with it. One of the beauties of the 2 was not having to pull 7 wires between the stat and the unit when 4 is usually all that's there on retrofits. Further they do not have remote temp expandability.

The 3 should work fine however for the two inquirers here.

Yep, my understanding is all residential 'flavors' are no longer being produced - STAT and Si.  If you stay with Ecobee for residential product then you're stuck with the 3.

Yep, plenty of others are unhappy too.

Yep, the STAT2 only required 2 wires for power and 2 wires for signaling.  Very friendly to retrofit jobs.  But forced you to use STAT versus Si.

Yep, no remote temp - have to get it from the local weather report.

We believe problems with 3 are significant enough that they're not useable in a multiple t-stat commercial environment.  We're 'centered up' on the commercial EMS Si 2 'flavor' and will continue to do so until we hear a definitive statement on if manufacturing of these will continue.

Best regards,

Bill

I went through four Climatouch stats in my home that varied from defective out of the box to lasting not much more than a year before finally switching to the Honeywell TH8320WF1029 (touch-screen, wi-fi, 3H2C). We love the wifi and the ability to remotely monitor and control the thermostat from anywhere using a phone or tablet.

I think I finally figured out that there's a good reason why all the pro's in my neck of the woods won't install anything but Honeywell or Emerson (White-Rogers) stats, and why that's all that the local HVAC supply houses carry. Those two companies know what they are doing, and their products just plain work, and stay working. I've heard plenty of positive coverage in the media about Nest and Ecobee, and I'm sure they must be fairly decent products....but I really just want boringly reliable as my most important key feature for a thermostat.

We have the Ecobee smart (older unit). And it has been an improvement over the original honeywell. I do like the remote access but the touch screen is just short of useless. The remote app is what we generally use for adjustment. Wish the app more mirrored the selection on the web login. We have had issues with loose wire connection over time. Been installed for about 1 year now. I know we all like fewer wires as do I but these smart thermostats are still only half wits. They need to close the loop and the furnaces and air conditioners need to communicate there operations with each other and pay closer attention to what is really working not just what is being told to be on.
