Honeywell Zwave Thermostat TH6320ZW2003 T6

Thanks for this info -- wish I knew this when diagnosing with Honeywell who ended up replacing all 3 thermostats with what looks like the same one (version 4.61 (ZDK 6.71.1) but with upgraded firmware from the original. They never even mentioned this other model an I worked with them for over a month on the issue. wow. Yep -- can't seem to find the 2007 version. Will have to keep an eye out for it. thanks again!!

Hi there --
Certainly appreciate your information regarding the 2003 vs 2007 Honeywell T6 Thermostat models.
I had to turn off logging on my 2003 models as the humidity was being recorded several times a minute reflecting the sensitivity of the humidity sensor. Your advice regarding the 2007 model prompted me to buy them as replacements to the 2003.

I just installed the 2007 model with software / firmware as referenced above. It's doing the same thing -- at least for the first hour of install. In the manual, I noted that ISU 1426 says that you can adjust the humidity reporting threshold -- (i'd set it to 10%) - there's no place to set it on the thermostat itself and I'm not seeing any parameters in my Homeseer 4 Zwave configuration screens. If I knew the parameter number and size, i could set it manually. But I don't have the parameter number. The ISU is defaulting to 1%.

I'm not using the secured mode.

Any suggestions?
thanks so much

I have 6 of the TH6320ZW2003 (Firmware 1.4.9, zwave 4.61) but I'm not seeing the flood of humidity reports. I'm on battery (no c wire) so that might be a difference BUT I can change the "Z-Wave Humidity resolution" both on the menu of the thermostat and by adjusting the zwave parameter 45.

By the menu - Menu, Zwave Setup, Hum Report, and then adjusting between 1% and 5%

If I retrieve parameter 45 on the root device I see the corresponding change (1 thru 5)

Looking at the z-wave alliance site I see that parameters 44 and 45 were added for the TH6320ZW2007 but they must have also been added to an updated firmware version of the 2003 device

I found the TH6320ZW2007 on Amazon

Does anyone know what the /U (TH6320ZW2007/U) represents?

Thanks!

is it this SmartStart they advertise?

A new Z-Wave feature called SmartStart will make it easier than ever to enroll smart devices into a home-automation system for instant interoperability and control.

The 2007 has the SmartStart but I don’t think it explains the “/u”

“Model TH6320ZW2007: Same as TH6320ZW2003 but TH6320ZW2007 has SmartStart”

I’m thinking that the /u is for the UWP mounting system.
