Want to know how to replace an old thermostat with a digital one?

If you are living in an older home and have an outdated thermostat, or if you believe your thermostat is defective; it is essential to know how to install a new digital unit in order to avoid the increase in heating and cooling bills. Upgrading to a digital thermostat is a low-cost method to help reduce energy prices whilst controlling the temperature in your home, making it easier and more effective. Knowing how to install a digital thermostat will benefit your home in making it an efficient, stress-free and comfortable environment.

Important Preparations:

Your thermostat should be placed about five feet up from the ground. In order to get a correct reading it should be away from any conditions that could adversely affect the temperature (e.g. drafts or sunlight). Should any of these conditions exist then you would need to contact your heating and air professional to move your thermostat location.

Tools Required:

Digital Thermostat,
Screwdriver,
Pencil,
Sellotape,
Small Level, and
Drill Driver.

Ready for Replacement:

Step 1: To begin with turn off the power to your furnace and air conditioner. Now, detach the cover of your old thermostat. Be aware that some units have lock in screws and others snap on and off. Consult instructions if you need to.

Step 2: You should now be able to unscrew the thermostat from the wall. Once you have disconnected the cover, you must label each wire on your system to note where they were attached in the old thermostat. (It is important to mark the wire with the corresponding letter and not rely on the different colors, as there is no standard color code on all units).

Step 3: Once the wires have been labeled, disconnect them from the terminals with the screwdriver. Note: tape the wires to the wall to avoid it falling back into the wall.

Step 4: Detach the face of your new thermostat from the base. With most digital thermostats, there will be a clasp at the bottom that when pressed, it will lift up to disconnect from the base. Station the base against the wall with the wires projecting through the center. Use a level in order to line it up accurately and mark the screw holes with a pencil.

Step 5: Now remove the base and drill 3/16 teeth inch holes where you have marked the screw holes and then insert a plastic anchor in each one of the holes. Then take the wires and feed them through the center opening and connect the base to wall with the provided screws.

Step 6: Take the screwdriver and connect each of the marked wires to the corresponding terminal on the new thermostat. If the connections do not match, refer to the manual for the correct wiring set up.

Step 7: Install new batteries into the main control unit, and then press the ‘Reset’ button to retune the program memory to its default setup.

Step 8: Connect the control unit to the base by snapping it into place. Turn the power back on and examine the thermostat to ensure that both the furnace and the air conditioner are in correct operative order.

Step 9: Finally, adjust the thermostat periodically to meet your lifestyle. You can save money while your away and still come back to a comfortable and pleasant home.
