How do I install and mount the Honeywell T6 Pro Thermostat?

First, push excess wire back into the wall opening and close the UWP door, ensuring it remains closed without bulging. Align the UWP with the thermostat and gently push until it snaps in place, then turn the power on at the breaker box or switch. The thermostat comes with a UWP Mounting System, J-box adapter, and decorative cover plate to facilitate installation.
