Installation

Step 1

Remove the fuse or switch off the appropriate circuit breaker to turn off power to the heating and cooling system.

Step 2

Remove the cover of your old thermostat by inserting a screwdriver into the slots on the sides of the thermostat (check your owner's manual on removing your thermostat if this method will not work for your specific model). This will expose its wires. Using the enclosed wire labels, label the wires and then remove them from their terminals. Unscrew the old thermostat's base from the wall with a screwdriver.

Step 3

Insert the screwdriver into the slots at the sides of the SimpleComfort 3000 thermostat and twist it to remove the cover. Place the thermostat base against the wall where your old thermostat was. The wires should feed through the wire opening in the thermostat's base. Mark the placement of the mounting holes on the wall with a pencil. Remove the base from the wall.

Step 4

Use the drill and 3/16-inch drill bit to drill holes in the marked areas. Then, with the hammer, tap the supplied anchors into the mounting holes. With the anchors in place on the wall, align the base of the thermostat with the anchors and place the control wires through the wire opening. Use the screws included with your package to mount the thermostat base to the anchors.

Step 5

Insert the stripped, labeled wires into their matching wire terminals. Do not allow exposed wires to touch other wires. Tighten the screws on the terminal block with a screwdriver, then seal the hole for the wires behind the thermostat with nonflammable insulation or putty.

Step 6

Set the "Gas/Electric" switch to match your system: "Gas" for oil or gas systems, "Electric" for heat pumps or electric heat systems.

Step 7

Insert two AA batteries into the thermostat, then snap the thermostat cover into place over the mounted base. Reactivate the power by replacing the fuse or switching the appropriate circuit breaker back to the "On" position.

Operation

Step 1

Set the mode switch to either "Heat" or "Cool" and the fan switch to "Auto." The current temperature set point display will appear. Press the down or up arrow to adjust the temperature.

Step 2

Set the temperature differential, or the degree difference that must occur before the thermostat kicks into action. By default, this is 1 degree Fahrenheit. To adjust this differential, set the mode to "Off," then open the cover and press both the up and down arrows simultaneously. Then press the up or down button to adjust the setting. When finished, switch the mode back to either "Heat" or "Cool."

Step 3

Set the time and day of the week so your program schedule will operate correctly. Set the mode switch to "Off," then press and hold the right arrow button for six seconds. Then press the up or down button to adjust the time. While the time is displayed, press the right button to show the current day, 1 through 7, with 1 being Monday. Press the up or down button to adjust the day of the week. Switch the mode to "Cool" or "Heat" to lock the settings.

Step 4

Program the thermostat. Set the mode to "Off" and hold the right arrow button for six seconds, then press it twice to display the day for programming. This will be 1, or Monday, by default. Change the desired day with the up or down arrow. Use the right or left arrow to navigate between the parameters of each day, and change each parameter with the up or down arrow. The parameters to program for each day are the time of day, the time, the heat temperature and the cool temperature. Repeat these steps for each day of the week. You can also use the Simpleset feature to match every day to Monday: After setting Monday, press the down button once to return to Monday, then hold it for two seconds. The days will count down. When finished, change the mode back to "Heat" or "Cool."
