“Can I replace my Honeywell thermostat model # T8112D1006 WITH this 7 day programable Wi-Fi model”

• You can certainly replace/upgrade your old Honeywell, as I did. Simplicity of instalation will depend on the wiring of your old thermostat and how handy you are. I will say, worst case scenario, Honeywell offers clear, easy to follow instructions to help you through the process.
