The Honeywell Chronotherm thermostat offers users great control over heating and cooling their home. The electronic thermostat has several programmable settings for different situations when you don't need the heat or air conditioning running. For example, if you leave at the same time every day and no one is in the home, you can set the thermostat to a temperature that won't run the heat or air conditioning when you're gone. This type of control saves you money on your home heating and cooling.
