Honeywell RTH6300B

The Honeywell RTH6300B is a basic digital thermostat built to allow homeowners to install it themselves. The design is very close to that of the Honeywell RTH4300B, but the backlit display is larger to make it easier to read.

Settings and the time and date are automatically saved, and will remain even after a blackout. This thermostat is compatible with a few more heating and cooling systems than the RTH4300B, accepting systems with heat pumps that don't use auxiliary heat. Only systems with back-up heat, multi-stage heating/cooling systems and electric baseboard heat are incompatible. Programming can be set for weekdays and weekends separately, allowing up to 4 different temperatures to be set throughout the day. This can save up to 33% on the home's heating and cooling costs annually.
