I bought this item after a friend of mine showed me his Prestige 1.0 system. This one, the Prestige 2.0 HD model, offers support for more RedLink accessories and more stages of heat/cool I believe. At any rate, it wasn't too hard to install, I had to use an extra wire to provide power to the unit from the furnace, but other than that it was relatively easy to install. Programming it is fun albeit a little confusing if you aren't familiar with HVAC jargon, as I am not.

I also bought the outdoor wireless sensor to have it show real-world outdoor conditions. All in all a very cool unit I'm enjoying very much.

I picked up two Honeywell THX9321R5030 Prestige HD 2.0 Thermostat from Plumbing Planet and had them in hand within 3 days. Both units shipped quickly despite being provided a longer deliver time and were installed by our HVAC technician during the replacement of our furnance & AC unit. These are identical to the THX9421R5013 unit except the 5030 unit can be wired or do wireless to the zone panel. We actually have one 5030 wired and the other set up wireless with no issue from either in over a month. All three thermostats are also reading the same outside temperature gauage which is conveniently displayed with your indoor and set temperatures on the home screen. A great product and quick deliver by Plumbing Planet made the purchase all that much easier given the units are not cheap.

Update 2/3/13: All three units are still working great. The wife decided to have fun with the themes (font & background colors) by setting up unique themes for each holiday/season. The only issue I've seen is the outdoor wireles sensor for temperature appears to be off by about 2-4 degrees compared to other temperature senors we have. It's not a big deal and I'm sure there is likely a 1 degree error rating either way but it's something I noticed. One other thing we noticed is that the wired unit in the master bedroom clicks when it's engaged for heating or cooling while the wireless unit makes no noise of course. Again, not a big deal but we do hear it click on/off when sleeping which is normal for any wired in theromostat.

Outstanding thermostat. It replaces a 24-year old thermostat that was not working properly. It did require a professional for installation, as the wiring was not the same as pictured in the installation guide and an additional wire had to be connected at the ac/furnace unit.
