To turn off or adjust the Window Protection setting on a Honeywell TH8321 thermostat to increase humidity in your house:

1. Ensure the thermostat is connected to an outdoor wired sensor or the Internet (Window Protection is only available with these connections).
2. Access the thermostat menu.
3. Locate the Window Protection setting.
4. Set Window Protection to "Off" to allow the humidifier to run up to the desired humidity setting without restriction.
5. If you prefer to adjust rather than turn it off, lower the Window Protection setting step by step and check for frost or condensation on windows each morning.
6. Continue adjusting to a lower number until no frost or condensation is present.

This will allow higher humidity levels in your home while preventing excessive condensation on windows.
