I am replacing an old mechanical White-Rodgers thermostat with a digital 5-2 day programmable one from Honeywell (Model # 6300B). The wires I have coming out of the wall are connected to R, G, Y, O, W2, and E. Pretty self-explanatory: just match the wires to the new thermostat. But the new Honeywell thermostat doesn't have a W2 or E terminal.
Based on the diagram I have on the installation manual--
C or X, B wires, do not connect
G or F wires, connect to G
W or W1, H, O/B wires connect to W O/B
--unused terminal in between--
Y or Y1, M wires connect to Y
R or RH, 4, V connect to R
Rc or R connect to Rc
I have a fully electric system: 2-stage heat, single-stage cooling. Voltage at the thermostat is 24v
I want to think that W2 can just go to W and E stays disconnected. But before I do anything, I just want to make sure. Thanks for the help in advance
You have a heat pump. You need a thermostat for "Heat pump with Electric back-up heat". Make sure the 'stat has either an "aux" (auxilliary heat) or an "E"(Emergency heat) terminal. The wiring instructions will be provided with the thermostat.

Hi, I have a 1997 Rheem Criterion II gas furnace with an electronic thermostat. On the thermostat, I have the temp set to 70 "hold", so it's supposed to keep that temp at all times. The problem I am having is that sometimes more often than others, the furnace should kick on, but doesn't. When this happens, the temp in the house might go down to 65, but the furnace never kicks on. If I flip the fan switch from "auto" to "on", still nothing happens. The only way to make the furnace start its cycle is to either turn the furnace power switch on & off again, or to adjust my temp on the thermostat to 65 (making it supposedly click "off"), then back up to 70, making it click "on". This seems to always work. I also have to add that sometimes the furnace will not turn off. The temp in the house might get up to 75, still running. I turn it off by cycling the thermostat up to 75 and back down to 70 again. I'm baffled that cycling the power switch on the furnace or cycling the temp up & down on the thermostat both work to kick the furnace on. Sorry for such a long post, but I tried to include as much info as possible. Thanks for any help! Joss

We recently (about 4 months ago we had a digital thermometer installed to replace the old one. Twice this week there has been an 'electrical burning' smell when you go into the living room (where new thermostat is located). At first we thought is was a new cordless phone so we unplugged that and the nightlight in that outlet and it seemed to have gone away. Tonight it is back. It appears that it is near the thermostat (opening in the wall where it is connected).
The walls are not warm, there is no smoke and we've checked from the basement and didn't see anything. (not certain of the brand below but i know it works for both heat/cold)
Mhenn, It is my guess that the 'electrical burning' smell is from your heating system. Since there is no smoke and the walls are not warm.... then there is no real problem. The smell maybe just dust has collected in the duct work that is burning off the central heating systems electrical heat strips. If you have electrical heat strips then that may be the problem. If you have a central gas heat system, it may be the same type problem. Hope this helps you. Henry

We have a honeywell series TH8000 thermostat that is stuck on "permanent hold". It is specifically TH8320U1008. Do you know how to 'unstick' it?

The air conditioner is not working and the thermostat says it's in recovery mode
by the outside unit, you will have a shutoff. pull out the shutoff, and unscrew the cover. 2 cylinder like fuses are inside. It is likely that one or both are bad. When you turn on the AC and the outside fan does not turn on... this is likely this is the solution.

I have a programable honeywell thermostat with a Circulation setting that ramdomly runs the fan, versus on or auto. The manual says that the fan runs 35% less on circulation but circulates the air randomly throughout the day even if the temperature is set up high when we are gone. It says it helps better circulation and cleaning. The debate is whether we should set it to circulate rather than auto during the summer for better cleaning or the air and lower A/C bills. What is the answer, What is the best setting and why?
If you want clean air without changing the temperature and without using as much power as on the A/C setting then put it on "Circulation" which just means you'll just filter dust etc out of the air. If you want to change the room temperature put it on Auto at your desired temp this will filter the air longer as it's running more but it will use more power than Circulation there's only a better setting if you tell me your exact requirement eg do you want to cool the room or just clean the air, or clean the air saving power??? otherwise if you don't care about the power cost then the "On" setting is the best as it filters non-stop and cools the air non-stop. Cheers

The green backlight on one of my brand new Honeywell UtilityPRO thermostats won't go off -- it goes dim, but not off, so we have this green glow in our room all the time. My other brand new UtilityPRO thermostat is fine -- a couple of seconds of inactivity, and the light goes off. There's no code 280 in the advanced functions... any ideas on how to set the backlight?
After posting that I was having the same problem, I found a solution.
I used these instructions http://www.hydro-temp.com/help/drawings/honeywell%2069-1894ES.pdf and followed the Installer Setup on pages 6 through 10. Basically you just need to enter the setup mode following the instructions, scroll to setting# 280 and change the setting from "1" to "0" then the backlight will turn off after 8 seconds. Don't change any other settings if you don't know what you are doing.

I have a blinking snowflake icon on my air conditioner, my air will not work. My heater will work fine but the air will not come on
When the snowflake is blinking the thermostat in in a delay mode designed to protect your compressor. If it does not stop blinking in 15min the stat is bad otherwise something is wrong with the AC

What does FR Return mean when thermostat says this?
it means that it is friday and your "return home" program is running. there isn't actually a "FR Return" alert, it just lines up that way because the day of the week line sits directly above the program line.
