Old-school dial thermostats such as the classic Honeywell Round do have a certain vintage appeal. They're also simple to use and to understand.
But looks count for nothing when it comes to saving money. Manual thermostats are notorious energy- and money-wasters because they rely on you to physically adjust the temperature. If you've ever forgotten to turn down the thermostat before heading out to work or for a long day trip, you'll know what it's like to have your HVAC system expensively pump heated air into an unused home.
Digital smart thermostats can be programmed to turn your heating or cooling system on or off at specific times throughout the day and night. Most have a holiday mode, which allows you to reduce the need for the HVAC system during long periods of absence.
