With a Wi-Fi thermostat, a user can control the temperature of the home from across the room or across the world. This type of thermostat is ideal for people with vacation properties or residents who are unable to adjust household heating and cooling temperatures themselves. Simply access the Web portal using a desktop, laptop, or tablet computer or smartphone and make the necessary adjustments. Indoor climate control could not be any easier!
You will need:
Step 1: Switch off power to heating and cooling system at its power switch or the circuit breaker box.
Step 2: Remove the old thermostat but maintain the wall plate with the wires attached. Most covers will either pop off or unscrew so a screwdriver may be needed.
Step 3: Verify that the current system will work with the Wi-Fi thermostat. If the thermostat features thick wires connected by wire nuts, the home probably has a line voltage system or baseboard heat and this is not compatible with some Wi-Fi thermostats.
Step 4: The existing thermostat wall plate contains different colored wires connected to lettered wire terminals. Note which wires are connected to which terminals because the same connections will be used on the Wi-Fi thermostat. Take a photo or write down a description and use the masking tape and marker to label each wire, noting the letter of the terminal to which it is connected. Do not label wires based on color because wire color does not always indicate the function of the wire.
Step 5: Rather than requiring batteries, a thermostat may contain a wire called the C-wire that connects directly from the home heating and cooling system to the thermostat. The C-wire should be connected to the C terminal on the thermostat.
Step 6: A home with a heat pump system may have wires connected to the O or B terminals. A jumper wire connects two terminals and may need to be connected to the new Wi-Fi thermostat. Some Wi-Fi thermostats include a jumper cable that connects the R and RC terminals. If your home system has both R and RC wires, the jumper wire can be removed from the new thermostat and the wires can be inserted into their respective terminals when installing the new thermostat wall plate.
Step 7: Loosen each terminal with a screwdriver and pull out the wires.
Step 8: Unscrew the wall plate from the wall, preventing the wires from falling through the wall opening and ensuring that none of the wire labels fall off. Wrap the wires around a pencil to prevent them from falling back into the wall.
Step 9: Separate the Wi-Fi thermostat from its wall plate.
Step 10: Position the wall plate so the wire hole is centered and pull the wires through the hole. Use the level to verify that the wall plate is level. Mark the screw hole positions on the wall with a pencil and remove the wall plate from the wall.
Step 11: Use a drill and properly sized bit to create pilot holes in plaster or drywall. Tap provided screw anchors into the pilot holes using a hammer.
Step 12: Position the wall plate so its holes are over the anchors. Insert a provided screw into each anchor and tighten it with the screwdriver or drill. You may want to re-level the wall plate prior to tightening the screws.
Step 13: Connect each wire to its correct terminal on the Wi-Fi thermostat wall plate. Insert the wire into its terminal on the inside of the wall plate and tighten the screw with the screwdriver. Repeat for each wire. If the home features a heat pump system, match the wires to the letters on the outside edge of the terminals, insert wires in the terminals on the inside, and tighten the screws.
Step 14: Push excess wires into the wall opening.
Step 15: Insert the provided coin cell battery into the Wi-Fi thermostat, lining up the polarity correctly. This battery will stick out slightly from its slot.
Step 16: Align the pins on the thermostat with the wall plate and snap the thermostat into place.
Step 17: Switch on the power at the heating and cooling system or circuit breaker. The thermostat display will illuminate and you can set the date, time, and thermostat functions.
