        I bought this thermostat because I wanted a usage feature on my thermostat which most do not. I have been pleased with all it's functions. It is easy to use and gives me the run times that allow me to use my HVAC system the most efficiently.

          This is a good product. Read the directions carefuly and you will be able to program the unit correctly. Watch for overlapping temperatures between cooling and heat if you set varying temperatures on different days. Since this unit has been up and running our office environment has been comfortable for all.
