______________________________________________________________________ Hi All, OK, I’m new to thermostats, but not instrumentation and controls… Anyway, I bought a ritetemp 8050, and it was reading 9 degrees high ambient temp, even while running just off batteries. Let it stabilize for hours, same thing. So, I returned it, and have since gone thru two more, same problem, but only 4-6 degrees high instead of nine, as compared to three analog honeywells… So, I went and bought a digital honeywell, and it was off of ambient by 4 degrees, after stabilizing for two hours (yes I removed the variables of sunlight, etc…and had them all running off of just batteries, not the furnace power–yet) It works, but I have to fudge the temp setting to make it work. Also, I tried to power it off the furnace power instead of batteries, which worked great, until I hit the backlight button–then it went dead! (It’s running on a new Bryant 90-plus, gas furnace, with an AC unit attached…) Now it’s running off of batteries, and the heat works, but I am very frustrated with the accuracy of this thing! Also, the batteries that are supposed to work for “a year” give me intermittent low battery indications??? this happened on two of the units with three sets of brand new AA’s…??? I called ritetemp–they are completely clueless! they think home depot may have a bad batch, and heaven forbid talking to them about adjusting the darn things!! (see below, please) Also, there is a hole on the back of the board to access a potentiometer–is this for temperature calibration, or is this pot an offset for the amount of time that it takes to stabilize temperature during cycling? I work with automotive HVAC temps in a R/D auto facility, and they weren’t sure, but surmised that it was the “offset” situation, and were unsure whether or not to tweak it… thanks so much for your help!!!! marc thanks for your help–I appreciate your time!

Once I found out there was a problem, I stopped mounting them on the wall and just let them sit on my hutch, in open air, next to the analogs (don’t know why the previous owners had three, as only one was in use, but they came in handy for a reference…) Any ideas about that pot? thanks, marc thanks for your help–I appreciate your time!

The best way to escape a problem is to solve it. marc “Re(2):problems with ritetemp 8050″ , posted Tue 23 Nov 21:50 ______________________________________________________________________ Also, do you think I blew a fuse when I engage the backlight feature? Shouldn’t I be able to run off of what is (in my opinion) a pretty standard heating/cooling setup? thanks again! marc thanks for your help–I appreciate your time! Xenos Webmaster “Re(3):problems with ritetemp 8050″ , posted Tue 23 Nov 22:03 ______________________________________________________________________ Wish I could answer that, I’m pretty much a Honeywell man today. I know they work. Xenos.

I think this third ritetemp is short-lived in my house1 thanks again1 thanks for your help–I appreciate your time! marc “Re(5):problems with ritetemp 8050″ , posted Sat 27 Nov 11:13 ______________________________________________________________________ I got a reply from Customer Service. They know they have a problem with these things. Hopefully they’ll give me the new version. Marc: The Potentiometer is for the low battery warning. The 8050 has no calibration, however the newer model 8050C can be calibrated +/- 4 degrees. I am sorry for your trouble with our product and I hope this information helps you. If you have any additional question please let me know. Thanks, Rene RiteTemp 888-515-2585 thanks for your help–I appreciate your time!
