This is a Prestige 2-wireIAQ kit with redlink technology. It’s white in color. This kit holds the THX9421R5021WW/U color touchscreen thermostat, THM5421R1021 equipment interface module, C7089R1013 wireless outdoor sensor, and two channel sensors.
For the past few years I have been looking for a full-shown Wi-Fi thermostat. I have bought other Honeywell variations also as the 3M-50 by 3M. These other thermostats were OK but some feature was generally missing. I had evaded the Honeywell Prestige & RedLink merchandise in the past caused by cost and the extra Internet Gateway you had to buy, however now I see extra benefits of the RedLink System and it’s worth every penny. The Wireless Outdoor Sensor is a great feature and is useful of you have many phases, a heat pump, HRV, or humidifier. The system I installed this on is a single state heat/cool system with an HRV. The Good: – Nice looking display with easy-to-use menu layout. Not a pretty "Retina" display, however good. – Advanced Setup has controls, alternatives, and lockouts for nearly every HVAC scenario you may be able to think of. – Equipment Interface Module (EIM) installs in your utility room and can control your "Indoor Air Quality" devices, decreasing the amount of wires to the thermostat and removes the need for other control modules on your wall. This was a must for me since I required to control an HRV. This thermostat gives me an choice to run the furnace blower when the HRV is on, which I need since my HRV is installed to my return-air ducting. – Works with Honeywell’s Total Connect Comfort system, which is available via the web or an app on your smartphone. This system lets you to setup alerts to email you if your equipment is not working and the temp is too high/low. – completely well-matched with Honeywell’s RedLink Product Line. – Outdoor Sensors comes with Lithium Batteries. – Has a "Circulate" feature for the fan, which runs the fan 35 of the time.
We got this thermostat installed about a week ago and I can only say positive things about this package so far. The touch interface is nice and the color display looks great. The icons are smooth with no jaggies or 8 bit looking graphics, everything looks crisp and the touch sensitivity looks spot on. The install was done by an HVAC friend of ours, I watched and am tech savvy, it could be pretty simple for a DIY’er if you were familiar with wiring and could read wiring diagrams on the furnace side of things. If you do not want to mess with furnace wiring this is something you should not try to install yourself. This thermostat only uses a common and hot wire from the furnace and has no battery backup. If your power is out this is dead. It has a CR2032 installed to keep your settings till the power does come back on. We have ours hooked up to a brand new furnace/AC/Humidifier and this unit controls it all with ease. It has an outside sensor that tell the outside humidity and temp and will make auto modifications to ensure your humidifier wont fog up your windows in the cooler months(a particular menu in the stat is setup to tweak this). The web interface is great, the GUI is well thought out and I have the apps for both iPad, iPhone and Android. They all look and work the same way. The app it self connects via the internet to the gateway (which isn’t included with this bundle from what I can tell) if you want mobile access to your heating and cooling you’ll have to pick up the redlink internet gateway and connect that to your router via a wired connection. In general this is great and with the redlink it s great alternative to the NEST stat, this has a ton of added alternatives that make this less of a novelty with real warnings and diagnostics potential. I’ll post back after some months with any extra thoughts or troubles we may have.
Let me start off by saying that this is meant to be installed by an HVAC technician. If you have the knowledge (or courage), then go ahead and install it yourself. I had this installed to get rid of separate heating, cooling, outdoor thermostats, and humidistat for my steam humidifier. So, there were a bunch of things to integrate and I figured to leave that possible headache to a professional. Now that it’s installed and operational, I must say that totally love the control this system gives me. It gives me complete control over my indoor air quality (hence IAQ name). The amount of customization available makes this suited for a big range of installation situations. And with the Redlink system, I can add on and expand afterward on. Here are some of the controls I find useful:- 7-day scheduling lets me set different conditions for weekdays, weekends, vacation times, and one-off events like a work-from-home day. And the system has a learning capability, so after some number of cycles it establishes what it takes to cool or heat to reach a wanted temperature and changes its transitions therefore to be at the set temperature on schedule. – Complete humidity control will include an integrated humidistat to control my steam humidifier in the winter (when it is dry) and a dehumidifier in the summer. I do not have a whole house dehumidifier, however the choice is there. The part that I like, although, is that without a dehumidifier installed, it can cycle the A/C system in such a way as to help control the humidity. It does this through periods of over-cooling (default 3deg difference, settable by installer). This isn’t as efficient as a separate dehumidier, especially on wet days, however may help keep it down some most days.
