Honywell Lyric Restarting issue


I moved a couple months ago and swapped out the old Thermostat with the Honeywell lyric. It worked fine for about 40 days and then it started having issues.

The unit constantly resets its itself for a couple hours every morning. This has been for about 10 days. I did an online help chat and they had me swap the battery for a new one... which was the correct lithium. The battery only lasted about week and I got the low battery indicator.

This has seemed to only start since it's gotten a bit cooler out and the unit doesn't run at all overnight.

The wires I have are W, G, Y, R - switch is set to R.

Any help is appreciated, thanks!

I would add a 24 volt common wire to the C terminal.
