How to Operate a Emerson 1F80 Programmable Thermostat


In this section we’ll discuss the basic operating features, such as setting the fan, choosing a system setting, manual operation, and overriding the program feature. Once again will use the 1 – F 800471 single stage thermostat in our example. The 1- F 860471 is basically the same; differences on the 1- F 850422 universal model are covered in a later module. To choose a fans setting press the fan button to select auto or on. Most people use the auto setting that runs the fan only when the heating or cooling systems is on. You can also use the on setting to run the fan continuously for increased circulation. To choose the system setting press the system button and select your option, choices include, cool which controls the cooling system, off which shuts down all systems, heat which controls the heating system, and auto, which switches automatically between the heating and cooling systems as needed. Most people use auto in areas where temperatures very enough to need both systems in one day. When using this feature, be sure to set the cooling system temperature at least one degree higher than the heating system temperature. In some cases the homeowner and or the equipment may be better suited to manually change from heat to cool. In this case do not use the auto change over option; to manually operated the thermostat simply press the system button to select heat or cool and use the up or down arrow to adjust the temperature. After setting the temperatures you want you can also press the system button and select auto to let the thermostat automatically switch between heat and cool. To override the programs and manually operate the thermostat press the up or down arrow to find the temperature you like and press the hold button. This feature bypasses the program and holds the temperature you set until you manually change it or press the run schedule button to resume the program. You can also temporarily override the program by pressing the up or down arrows to adjust the temperature, this bypasses the program temperature until the next program time. When using temporary hold in the auto mode press the up and down a row simultaneously to switch between the heating and cooling systems and adjust the temperature as needed. To cancel a temporary setting, press the run schedule button.

  1. The Nest Thermostat works really well>>>t.co/YBiRUbyrdL   and like that I can change the temperature via Wifi with Alexa and when away from home on my smart phone. And also like that I can monitor the daily usage history. I'm glad I finally decided to make this purchase.
