Check on the thermostat look for a little reset button you can use a pen to reset it. Try this let me know if it works.

I have a honeywell focus pro 6000 temp in house doesnt change unit runs constatly. thermostat says 78 thermomiter on other end of house says 72. changed batteries


It's possible you have a lot of dust build up inside the stat. If it has batteries remove face from wall and blow out. Take outside to see if temp will change. Plug the hole in the wall where the wire comes through. If all fails, replace. Turn power off, take wiring picture, replace, turn power on. Good Luck!!

Why does the temp read 94 on thermostatwhen it is actually 78 in house. I had to turn ac off because it wants to bring down that 94 temp.


Wow... spotted this hours ago... and thought a better man than I would answer this...

Oh well:
If it is your basic old fashion <not smart> spring operated Honeywell...
First obvious assumption ought to be... 'cuz it is broke.

On the modern electronic ones...
Possible... but not likely.

These things have their own batteries.. When they RUN LOW...they start acting strangely... The second best guess for troubles are the batteries are low.

The FIRST best guess of course is ... You have not read the instruction manual.

Fear not... no one ever does.

If it is a Combo AC/heater.. control... take a deep breath... step back and chech which mode is on display.

Could be in heat... cool... program...
Auto.. Running or on HOLD...
and the precise nomenclature of the unit are vital to establish price and direction.

Typically the only concern for working on these yourself... is shutting of your electrical breaker... to avoid sparking anything while changing it out.

Look at the wires... Take clear pictures!

Finding batteries is pretty cheap... as are most THERMOSTATs

(unless you are filthy rich and don't mind paying $300 (+/-) for a "PRO" to <maybe> do it for you.

Look to the batteries first!

Good luck & happy hunting!

My batteries died on mt heat control, I changed them and now have nothing


http://www.gogeisel.com/geiselonline/support/Honeywell/CT3300_CT3355.pdf this is the programming manual- they have a note that if you show low battery after replacing the battery- put the battery in backwards, wait 10 seconds, then put the battery in correctly again to reset it- you will have to reprogram the clock time and date and any settings you had previously.

Honeywell ct3200 thermostat won't turn on


DON'T BUY A NEW ONE JUST YET! IF THE BATTERIES DIED & THERMOSTA LOST POWER, IT MAY HAVE LOST IT'S MEMORY. IT MOST LIKELY WENT BACK TO FACTORY DEFAULT SETTINGS, & NEEDS TO BE RE-PROGRAMMED THROUGH THE INSTALLER SET-UP MENU. HOPEFULLY YOU HAVE THE PAPERWORK FOR THE THERMOSTAT STILL & CAN POSSIBLY DO THE SET-UP YOURSELF. IT SHOULD HAVE STEP BY STEP INSTRUCTIONS FOR THIS IN THE INSTALLATION GUIDE (NOT THE OWNERS MANUAL)

We have a Honeywell T8132A1049 thermostat/ cooler- we can't find a manual for it. It also says Bat Low on the screen but I have replaced the batteries with brand new ones and tried resetting it .....


Here is a link where you can download the user manual. It says to remove the batteries, wait 1 hr, then install fresh batteries. When the page for diplodocs opens click on security number and enter the code it shows to download the manual.

Even after replacing the battery, the programmable Honeywell thermostat still shows "Low Batt."


Turn control to off. Remove the batteries for at least one hour. If the display message still reads "bat lo", leave control off, batteries out, and disconnect the red wire on back and wait another hour. Reconnect red wire, put new batteries in and turn system on. It's like a reboot.
