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.
