Honeywell RTH2510B

The Honeywell RTH2510B is a low cost energy staving thermostat. It allows each day to be programmed differently, with separate temperature settings for up to 4 periods per day. This allows less energy to be used at night and at times that everyone tends to be out of the house, saving up to 33% on annual heating and cooling costs.

Temperature control is precise to one degree of error. The display is backlit to allow for viewing in low light, and displays temperature in Celcius or Fahrenheit. This thermostat is compatible with heating and cooling plus heat pump systems, but won't work with electric baseboard heat. A 1 year limited warranty is included.
