There is a need to calibrate your thermostat due to some rather obvious reasons. The moment your thermostat starts displaying inaccurate temperature readings, there is a problem. You may attempt to change temperature readings severally so as to correct the issue but in real sense you are damaging your thermostat. Also, the energy bills may tend to increase drastically if you keep on making adjustments to the thermostat.

Thus, calibrating your thermostat ensures that the temperature remains consistent throughout and that you are comfortable as well.

After identifying reasons for thermostat calibration and causes of improper thermostat calibration, we now seek to find out how to calibrate thermostats without involving professionals. There are few steps to follow to achieve appropriate thermostat calibration.

1. Select the correct method

Does your thermostat have a mercury switch with mercury inside it or does it use a calibration screw? This is the first thing you need to determine before moving on to other things. For our case, the Trane xl824 thermostat uses a calibration screw.

2. Ensure the thermostat is accurateEnsure the thermostat is accurate

How do you measure the accuracy of your thermostat in the first place? Simple! You will use a regular indoor thermometer. Turn on your thermostat. Stick your thermometer on the wall next to the thermostat by using a masking tape.

Ensure the thermometer and walls do not get into contact by placing a piece of towel in between them. Also, the two need to be in a position whereby they are not affected by any weather interferences such as sunlight as this tampers with the readings.

Your thermostat should be on for about 15 minutes and then compare the temperature readings of the two. In case there is a temperature variation that is over 1 degree, your thermostat needs calibration. If the readings are similar, then your thermostat is okay. It is advisable to carry out this procedure at least once a year.

3. Clean the thermostat off any dirt

Because dirt and dust may tamper with the calibration of your thermostat, you need to ensure that your thermostat is free from the two. You can either blow your thermostat or open it up once and for all to clean the dirt in its interior.

Get rid of the thermostat cover and use a clean soft brush to carefully clean the contents inside and use a soft piece of cloth for the outside part. In other cases, you can use a clean dollar bill to clean in between the magnetic connections.

4. Make tight the calibration screwMake tight the calibration screw

Locate where the calibration screw is. Usually, it positions itself in the interior of a curved piece of metal in the thermostat. Use the right screwdriver for the job to rotate the screw from side to side until the contacts unlock.

After a few seconds, turn the screw once more till the contacts lock. You have reset the contacts.

5. Ensure the level of mercury is straight

Use a spirit level that is standard to make sure that the mercury is straight for it to work properly. If you do this and the thermostat still refuses to work, it is time you look for a profession.

6. Check the wiring

Before closing up the thermostat, check the wiring if it is in proper condition. Clean any dirty wires and replace the ones that have rust and corrosion.

After the last step, you can repeat step 2 just to ensure that the readings are accurate and you have successfully calibrated your thermostat.

Conclusion

Trane xl824 thermostat calibration is a very straightforward procedure that you can do on your own. Calibration ensures that there are consistent temperature readings and that you do not pay huge energy bills. Always ensure that you calibrate your thermostat yearly to be on the safe side.
