Honeywell Heating & Cooling - Recent Questions, Troubleshooting & Support


Do you mean the alert flag (a triangle with an exclamation inside it) or a different symbol? The Alert flag will appear with another message on the screen. If it is time to replace the battery, you'll also see "BATT" to the left of the flag and a low battery icon somewhere along the top of the LCD screen. If the thermostat is set to alert you to change the HVAC system filter regularly, you'll see "REPL" to the left of the alert flag.

This is from the T4 Pro thermostat manual on pages 6 and 7. See https://forwardthinking.honeywellhome.com/assets/tseries/resources/install/T4%20Pro%20User%20Guide%20-%2033-00188EFS.pdf . The T6 Pro uses the same alert behavior.

I hope this helps.

On the Pro4000 model you hold the 2 arrows until you go into setup mode. Then arrow up ONLY til you get to option 13. The display will read 13 and 1, press the DOWN arrow and it will read 13 and 0. This turns off Adaptive Intelligent recovery. Now hold the 2 arrows til you see the normal display screen. You are done.

I just did this with a Honeywell tech rep on the phone.

Love the honey well product. Probably has a blown fuse. May be in the plug portion of cord or in the fan itself.
