Question: Does this product communicate directly with Honeywell REM5000R1001 Portable Comfort Control?
Document: Converted from an old Lennox to this with a two-stage heater and two-stage cooler. Determining which wires were which took a little time; even though they were labeled it took a little time to translate from Lennox call outs to Honeywell. Likely a non-issue for a HVAC person. Took about an hour of research on what the wires meant, and about five minutes of attaching wires to screw studs.Best feature is the fact that it integrates with a Portable Comfort Control.
This is a replacement for the first one that I bought. The first one failed on installation. Amazon sent the replacement very quickly, it installed quickly, (I had all of the installation items in place from the first unit), it worked perfectly, connected to the Equipment interface module, and outside temp sensor, and remote control easily. Thanks.
The ability to control the system & schedule from online and/or smartphone app is great, and that too has worked without a hiccup from the start.I can't say enough good things about this system - it rocks! The fact that DIY-installation isn't exactly easy is not really a big deal if you are aware of it ahead of time, and you simply do your homework by fully planning out your install before you start doing it.
It will work great out of the box or you can really get it to do magic by getting the accessories and tweaking the settings#4  Does NOT require a EIM module to operate the system assuming you have a wire with enough strands to connect all the features directly to the furnace. .
I installed three of these in one of my rental properties along with an outdoor sensor and Red Link Gateway ... both my heating guy and I had no experience here. The directions were good but the telephone support  was INCREDIBLE. In just a few hours we had all installed and fully operational with PC and iPad software controlling the thermostats remotely. I know control the entire home from over 100 miles away and reducing my oil bill like crazy!
Looks like a good thermostat. Installation instructions are near useless to a DIY'er. I had to call my HVAC person to get correct and unambiguous instructions for installation. Honeywell sells this unit to the DIY'er, but doesn't document it for the DIY'er. Even an HVAC technician would probably be guessing how to install this thing.
But, if you Google around patiently, you can find the resources you need. To its credit, Honeywell does provide a lot of detailed documentation, it's just not written for the non-professional. If you're not comfortable with HVAC basics and basic electrical concepts, you are far better off having a pro install your system.But if you are willing to spend time researching and puttering here & there, you can indeed successfully self-install this system - even all of the extra available bells & whistles.
Bottom line this is a very simple installation ASSUMING you have the existing wiring in place to connect it out of the box.#2 Once you make the wiring connections and snap on the Tstat face the unit is extremely easy to program, It has the option of allowing you to program using a Q&A; format or a direct user input without questions format. idiot proof.#3 It has the ability to connect to several of the Honeywell optional accessories with a push of a button.
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.
The T Stat will immediately recognize the device and display the outside airrtemp and humidity on the T stat display. Quick and easy.#4 If you want to take advantage of the wireless Apps top program your T Stat from your Phone or tablet you must purchase the Honeywell Redlink Router. Again when you purchase this it installs exactly as described above. Plug in the router and push the connect button.Keys features to consider:#1  This T Stat qualifies for energy rebates from many utility companies.
