Question about Honeywell CT3200 5-2 Day Electronic Programmable Thermostat Heater

4 Answers

Battery Issue I just replaced the batteries on a Honeywell CT3200 thermostat. It still displays Battery Low message. I tried 2 sets of fresh-from-the-package batteries. Any suggestions? Thanks

    I have the same problem. bat lo light remains on even after putting in batteries backwards for 10-20 seconds and reinstalling the right way. I checked the circuit breaker and no blown circuits. any ideas?

    Same Problem. Temporarily reversing the batteries worked for me too.

    I had the same problem and reversing the batteries worked. Now to figure out how to re-program this thing.

    I have the same problem. Last year it was the same, I cleaned the contacts with alcohol and didn't have a problem again until this year. The battery low display continues to show after 3 sets of new batteries. No the display is blank.

    Awesome, reversing the batteries temporarily worked like a charm. Heat back on now, thank you :)

Found the MagicStat 3200 manual online. I just fixed that problem. "If ?bAt Lo? continues to display after replacing the batteries, set the System switch to OFF, insert the batteries backwards, wait for five to ten seconds, and return the batteries to their correct orientation. Then reprogram." Note: The battery connector is very temperamental. If your display is still blank make sure the connecting metal pieces are free of corrosion and both AA batteries are connecting to the metal, especially on the right side. (You can use a small nail file to remove some of the corrosion if necessary.)

I have a two wire thermostat system. I switched the thermostat from a mercury one to the Honeywell CT3200 with dip switches set for my electric forced air furnace that is 31 years old. The white wire is...

If you look closely at the installation manual page 6&7 it tells you settings to use for your type of system. If I'm not mistaken you will need to back out screw "b" 360°. Hope this helps!

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.

Bat lo flashing periodically

You need to change batteries. The bat lo light flashes when you have about 10% battery life left. Rus

The bat lo message will not go away even after replacing batteries.. No functions either

One thing you might want to try is to remove the batteries and wait for a few minutes until everything clears. It could take around 10 minutes or so. This will reset the thermostat. Also look on the back and/or on the board of the thermostat to see if there is a reset button.

I hope this helps! :)

I replaced the batteries in my Honeywell CT3300 and the "Bat Lo" message won't go away even with fresh batteries. Is there a reset button or something?

Per manual do this: System set to Off Remove batterie Replace IN REVERSE POLARITY POSITION or 5-10 seconds Put back in with CORRECT POLARITY Reprogram per sticker on back of thermostat. Done. Just did this myself and it's simple and effective! PaulHaven
