ENERGY STAR® Programmable Thermostat Program. 2 The ENERGY STAR Programmable Thermostat program provides a GasNetworks 3 incentive for the purchase and installation of up to two ENERGY STAR labeled 4 programmable thermostats per household. According to ENERGY STAR, programmable 5 thermostats are more accurate than manual models, contain no mercury, save energy, and 6 are, therefore, better for the environment. Over 250 different thermostat models currently 7 meet ENERGY STAR guidelines – up from only 60 five years ago. Each ENERGY STAR 8 qualified model thermostat includes four default program periods per day, as well as a 9 two-degree accuracy to keep home temperatures more even.
