As you turn the dial to set the temperature a click is heard and an indent felt every 2 degrees. A deeper indent can be felt at the 10 degree increment marks. These audible indents make it easier to adjust for energy savings and to check the temperature setting. You can replace your existing Honeywell thermostat or other two to four wire thermostats. This thermostat can be used for heating systems only.
Professional installation is recommended.
