Best Single Stage Nonprogrammable Digital Thermostats

Single-stage heating means the furnace has one level of heat output. An example would be if you only have a gas or forced air heater or if you have an electric AC system,  and then a separate heating system. A single stage system is the most common type of system, and it's common all over the country.

Generally 6 wires or less are used in single stage systems.  Single stage non programmable digital thermostats are easily adjustable and will display the temperature at which your heater and air conditioner will turn on.
