Q:

How do you differentiate between a digital and non-digital Honeywell thermostat?

A:

Quick Answer

As with all thermostats, Honeywell digital thermostats use a digital display, most often a liquid-crystal display, to show information regarding operation, while non-digital Honeywell thermostats have an analog display. Unlike non-digital thermostats, digital thermostats can often show far more information than the just current and target temperature.

Non-digital thermostats use mechanical action to set the desired temperature. An in-home thermometer reads the current temperature, and the thermostat turns the heating or cooling system on or off in response when the temperature rises or falls below a certain point. Most thermostats use a small lever or rotate to allow users to change the desired temperature.

Digital thermometers instead use a digital screen to show information. The current temperature and target temperature are almost always displayed, but the display may also show the time, the temperature outside or a wide range of other information. Digital displays allow users to set their target temperature precisely, and some have lit screens to make them easier to read at night.

One popular subset of digital thermostats is programmable thermostats. While some non-digital programmable thermostats are available, they have largely been supplanted by digital models. Programmable thermostats can be set to target different temperatures throughout the day, allowing people who work away from home to turn off their systems when they leave and power them on before they return. Programmable thermostats are more expensive but can provide substantial energy savings over time.
