Smarter than me

I am amazed at what this thermostat will do but setup was a challenge. When I got deadlocked on setting up the humidistat, I called Honeywell Customer Service. After asking my question I was politely put on hold while she researched my problem. Several minutes later she advised me that she could not give me the answer as I was not a HVAC contractor. Not happy with her reply she advised I call a contractor..I was able to do so reluctantly. Bottom line I think it's a great product but setup is quite complex.

Honeywell Controls Rule

Honeywell VisonPro 8000, great product. Twenty seven years in the commercial/industrial HVACR field, Honeywell stand alone temperature controls continue there legacy. Control is adaptable and incorporates humidity with setpoint setting.

Great Thermostat

This is an improvement on the standard Pro 8000 thermostat as it allows some additional A/C control over both the room temperature and humidity. Installation is quick and easy even for those of us who aren't very familiar with A/C systems. Just follow the color coding and select the correct A/C "type" and it works. Programming is intuitive and easy to understand.

Humidity Control Is Great

Had HVAC servicing company install the thermostat during their annual system check. Installer did basic progarmming and we completed the programming ourselves to suit our needs. Programming is very easy to do by just following the installer instructions. We noticed a change in the quality of the cooling immediately because of the ability to control both temperature and humidity. Really good investment especially in FL.

Excellent product - easy install

I ordered on a Sunday evening, the product shipped on Monday, and I received it in Texas on Thursday - great service from PEX! The thermostat was a very easy and straight forward install with no surprises. Programming is very intuitive and easy with the large touch screen interface. Been installed for 3 weeks and working great - highly recommend.

Q: with this thermostat function as follows: owner sets temp (ie. 76deg.) and can then put in a code on keypad, which prevents anyone else from changing the temp, except the owner who set it, with the code.???? thanks Ken

This thermostat only provides the ability to lock the screen by changing a setting in the Installer Setup Menu. The setting can be changed fairly easily by anyone who accesses a manual for the thermostat. You may want to consider a Robertshaw 9725I2 thermostat if you desire pass-code lockout. Thermostats in Robertshaw's i2 Series have a similar installer setting, but they also allow installers to enter a four-digit pin to secure access to the settings menu.

Q: What should I set the temperature to in Fl. in the summer when I will be gone for several months with this thermostat that has dehumidity control?

Hi, Bought one of these for exactly the same reason..maintain the humidity while we were away. However, the problem is that there is no feedback on equipment operation. We experienced an equipment failure so were unaware that the inside temperature was in the 90's when we returned. We have since replaced all our thermostats with WiFi connected units which allows us to monitor the temperature, humidity and operation of the A/C units remotely..that is the feature we really like.

Personally, for hot months I would set it to 78 degrees but then (and I think just as important) I would also run a dehumidifier which can continuously drain into your sink.

This unit can be set to control the level of humidity in the home separate of the temp. It will decrease summer humidity. It will run the the air conditioner up to 3 degrees below the set point to reduce humidity. As far as what to set it for depends on the area and materials your home is made out of. The attached article should help you decide. http://www.fsec.ucf.edu/en/publications/pdf/fsec-pf-438-09.pdf Sent from my iPad

Honeywell recommends the same cover plate for both those units (part 32003796-001). You should have no problem using the one from the existing TB8220U1003 unit with the new TH8321U1006 thermostat.

Q: I have a TH8320 thermostat with a broken screen that I need to replace. This model is intriguing because of the humidity control. Can this model be used in place of the TH8320 and if so, can it be installed on the same coverplate?

You can use this unit to replace the the TH8320. It should fit on the same cover plate.

- Bill P

Yes, this unit is essentially a TH8320 with the humidity control added. The size, features and electrial hook up will be the same but you will now have humidity control -- and it will fit on the same coverplate.

Set to "O" to turn the backlight OFF. Use function #0280 if you would like to change the setting.

- Silas the HVAC Engineer

Touch the SYSTEM area then press and hold the middle square at the bottom to get to the advanced functions setup. Scroll through the function numbers to Function 280 and change the setting to 0. The backlight will stay on for 8 seconds after you touch the screen than cut off.

Q: This thermostat refers to a "Dehumid" control...Our heating and cooling system has a humidifier control feature to bring moisture into the air on dry windy days...What does a "Dehumid" control mean? We need a thermostat that allows us to add moisture to our home due to asthma. If this is not the right model for us...can you recommend the correct model. Thanks

According to the manufacturer, the Dehumidification control: TH8321 models monitor the indoor humidity level and automatically activate the cooling system to reduce humidity by lowering the temperature by up to 3 degrees below the current cool setting. Please refer to the Installation Manual for more information: http://s3.pexsupply.com/manuals/1249544874360/Honeywell_TH8321U1006_Install_Guide.pdf

Dehumidification control is where the thermostat utilizes your heating and cooling equipment to remove moisture from the air. I do not believe that this thermostate would be the proper model for humidifying...adding moisture to the air. I am sure Honeywell makes a thermostat for your purpose but I do not know the model.
