Great System
By C. Rogers on Reviewed in the United States on January 25, 2017
I bought this to replace a Honeywell VisionPRO IAQ. My need was to have wireless remote monitoring and control. The existing system was installed by HVAC contractor on a new home and heating/cooling system. My system has an outdoor heat pump single stage with a two stage air to air, air handler. I'm not a HVAC professional, but I have a background in industrial power plants. The new Honeywell YTHX9421R5127WW Prestige IAQ Redlink was easy to install and setup. The setup is fairly intuitive, but did require me to do some research for certain settings that I did not fully understand. The instructions are pretty vague and probably written for a HVAC professional. But I'm confident that my setup is correct. The display as shown on the picture is much nicer than it looks in the picture. I was pleasantly surprised and think I could not have picked a nicer unit. Also, the temperature sensors included with this kit are for the return and discharge ducts. You can set up limits for minimum and maximum temperature deltas and alerts. This is a useful feature to determine if your system is functioning properly. I was able to reuse the existing outdoor temperature sensor as well. I still have room for one more sensor as well (hard wired), and multiple wireless sensors. The included Redlink Gateway was a breeze to setup and install. I'm using a free app from Honeywell to monitor my thermostat and system. This was easy to setup and use. The Equipment Interface Module hookup was fairly simple and only two wires are connected to the thermostat to power it up. The EIM and thermostat communicate wirelessly to each other and through the Redlink Gateway. I'm not utilizing all the available feature this system has but many of the features. The thermostat also has a USB port to download the settings to a thumbdrive as well as read and load the settings from a thumbdrive. This is handy if you should loose your settings or have to replace the unit.

Bad control module, but deal was good enough to offset that
By Rmchicago on Reviewed in the United States on April 22, 2022
The control unit i received in this kit simply did not work, thankfully we had a spare and once we swapped it out it was communicating with the thermostat. The unit itself was in mint condition so I’m guessing it was a lemon and why the cost was reduced so much but the description did not mention it was not working. This thermostat gets the job done but if you’ve had a nest or used to their software prepare to be disappointed. The thermostat is a resistive touch screen, think pre iphone technology, the app is ok but definitely not as sleek as Google’s offering.
