Honeywell RTH7600D

I am frustrated with the obscure wifi settings menu, which should be a basic feature.

I really like the new backlight and the programming feature for weekdays and weekends. The programming is easy and simple but lets me do really cool things. I can balance how much gas vs electricity I use by programming one to have a lower turn-on temperature than the others, or, for example, starting the gas furnace earlier to help me wake up and take the brunt of the heating chores from the electric heat.

I noticed a significant improvement in the temperature control of the thermostat. The rooms maintained a consistent temperature, and I felt warm and cozy throughout the evening. Rephrased: The temperature control of the thermostat significantly improved. The rooms maintained a consistent temperature, and I felt warm and cozy throughout the evening.
