Hi AJ8,

Thank you for reaching out and we're sorry for the delay.

This strange heating/cooling behavior usually occur when the power is unstable on your thermostat. We could fix this by connecting a C (common wire) to your thermostat. Check for an unused wire from your HVAC unit and that could possibly be a common wire we can use.

Check out this link to know more about C (common wire)

I hope it helps,

Ryan
