Review: Nice Feature - This is a nice upgrade to my TH8320 thermostat. A quick glace at the stat while walking through the house lets me see what temperature it is outside not to mention the benefits during adaptive intelligent recovery. Install was a breeze for my dad who's worked in HVAC for 30+ years. Only downside is the back of the house faces east which is where the condenser is as well as this sensor. In the mornings, even though it's not in direct sunlight, it reads the outdoor temperature between 8 and 10 degrees higher than it really is on a sunny day even in the winter. I think the sun is warming up the siding of the house and reflecting some of the heat causing the discrepancy. I just adjust the temperature in my head and am satisfied with that. By the afternoon when the back of the house is shaded, the temperature is consistent with my outdoor thermometer. I could probably use a better placement but I'm not overly concerned about it since the thermostat doesn't go into recovery until the evening so it isn't throwing off the recovery calculations. It's been installed for four years and worked without a hitch.
Review: Web page Technical error - Be careful when ordering this Item. I was shopping for a programmable thermostat when I ran across this item. I thought it would be great to see the outside temperature displayed when checking my thermostat. I purchased a Honeywell RTH8500D thermostat to use with this sensor. The thermostat was on sale and the desertcart web page for the sensor indicated it would work with the thermostat. I copied and pasted part of the technical details from the web page for the sensor below: "Technical Details: Outdoor temperature for display on the T8600 or T8500 family thermostats." Or link to the page: Honeywell C7089U1006 Outdoor Temperature Sensor [Misc. ] After receiving, programming and starting the installation process, I discovered the sensor would not work with the thermostat. The thermostat sub-base lacks the terminals required to connect the sensor wires. I downloaded additional installation instructions and discovered a TH8320U1008 VISION PRO 8000 thermostat is required for the sensor feature. I returned to the sensor web page and noticed the reference to the VISION PRO thermostat was listed. Trouble is it also advises it works with the T8500 family thermostats. It does not. I returned the thermostat to desertcart and ordered the correct unit. However it costs more and Honeywell won't warranty it unless it's installed by a PRO. They don't define what a PRO is. Anyway it's very easy to configure, install and program. The creature's been operational for several weeks now and I'm pleased with It's performance. desertcart treated me very fairly with this issue, but the error is still on the desertcart web page for the sensor.
