Replacing an old thermostat? Want to do it yourself?
Try these simple steps to replace your thermostat. All you need is a screwdriver, a small white tape and a lot of patience. It may be a simple process but it certainly needs your vigilance!
Step 1: Turn the Breaker Circuit Off
Before you pull open your thermostat, you need to shut the power off to your HVAC system or you could get electrocuted. Find the circuit breaker for the HVAC and turn it off. Do not begin without turning the breaker off.
Step 2: Remove the Hardware
This is the step where your screwdriver comes in handy. Once, you have made sure that the power is completely off, unscrew the hardware casing of the old thermostat and keep it away from it before actually removing the wires.
Step 3: Identify the Colors of the Wires to their Corresponding Terminals
This is the most difficult part of installing a new thermostat.
There are wires of multiple colors in the thermostat attached to different terminals. It is quite impossible to remember that the wire of which color was connected to which terminal. Grab a piece of paper and a pen. Note down the colors of each wire on one side and the terminal with which is connected on the other side in front of it. Double check your list just to be sure. Making a mistake with the wires is very dangerous and may prove to be fatal.
Step 4: Detach the Wires from Terminals
Once, you have made all notes, use the screwdriver again and start disconnecting the wires from their terminals. Make sure no wires are damaged in the process and keep the screws safe in a polythene bag so you can use them later for screwing in the new thermostat.
Step 5: Screw in the New Thermostat
You need to begin with the back board of the new thermostat. Place it on the wall where the old thermostat was installed moments before and gently pull the wires through the holes in it, inside it. Then, screw the box to the wall with a screwdriver.
Step 6: Attach the Wires with the New Terminals
Use the list you have prepared earlier and attach the wires to their respective terminals. Check your selection twice before screwing the wires in. Be careful and patient while you are doing it. It is not as easy as it sounds.
Step 7: Attach the Thermostat Screen to the Back Board
Just screw in the thermostat screen on the back board and switch on your circuit breaker. After a couple of minutes, turn on your furnace and see if the thermostat is functional. It should be operational in seconds.
