Honeywell thermostats are great in their efficiency and performance. They have been consistent in their functionality. So if you’re trying to make the best use of your Honeywell thermostat then you have come to the right place.
It is possible that your Honeywell thermostat gives a warmer or cooler reading than the room feels.
The accuracy may be compromised if you do not calibrate your thermostat. In this article, we are going to discuss how you can calibrate your Honeywell thermostat. Read ahead to learn more about it.
Do you have to calibrate a Honeywell thermostat?
Yes, you should calibrate a Honeywell thermostat if you’re trying to maintain an ideal temperature inside the room. It is also essential if you’re trying to get an accurate reading of the temperature in the room.
Calibrating your Honeywell thermostat will help you get an accurate measurement. This is the foundation of quality service by the thermostat. Your thermostat will be able to perform better if you calibrate it.
Without calibrating your Honeywell thermostat, it may end up losing its accuracy. The device may fall out of specs. In addition, it may end up providing wrong measurements regularly.
So the quality of the device will be threatened and the equipment longevity will be compromised.
How to calibrate Honeywell thermostat?
Calibrating a Honeywell thermostat is a rather simple process. You will first need to figure out the difference between the room temperature and the thermostat temperature. Then you should set the thermostat temperature offset parameter in order to account for that.
In the following section, we will take a look at how we can calibrate different kinds of Honeywell thermostats.
Honeywell manual thermostat:
In order to calibrate a manual thermostat, you will need to follow these steps:
Clean the thermostat:
You will need to clean the thermostat. If you fail to get an accurate reading on a thermostat, you should first clean the thermostat. First of all, remove the cover of the thermostat and clean it from the inside.
Make sure that you are using very soft brushes for the job. There are many sensitive parts inside the device and you don’t want to mess with them.
Tighten the calibration screw:
Manual thermostats come with a calibration screw. You will need to tighten the calibration screw. You will find this screw inside a curled metal piece in the thermostat.
Use a screwdriver that fits the calibration screw. Now you will need to turn the screw back and forth. Wait for a while and turn the screw back again until the contacts close again.
Honeywell smart/digital thermostat:
If you’re trying to calibrate a smart or digital thermostat, here are the steps that you will need to follow:
Determine the temperature differences:
In the first step, you will need to determine the temperature difference between the thermostat and the actual room temperature that day. This will help you plan the next step.
You will need to identify the number of degrees by which the thermostat is inaccurate.
Access the settings:
Now you will need to enter the calibration mode in the thermostat. The Honeywell thermostat is supposed to come with a set of instructions for this step.
Adjust the calibration:
Now you will need to adjust the calibration. You can adjust the thermostat to both positive and negative numbers. The temperature change will be displayed on the screen.
Exit the settings:
Now it is time to exit the calibration settings. You can now go back to the main screen of the digital or smart thermostat. Simply press on the exit button for this step.
Honeywell round thermostat:
If you’re trying to calibrate a Honeywell round thermostat, here are the steps that you should follow:
Check the level:
Now you will need to check the level of the thermostat. You can use a bubble level for this step. Make sure to tighten the mounting screws when the subbase is leveled.
Change the anticipator:
Now you will need to move the anticipator. If the furnace is cycling on and off too often, you should move the arm of the heat anticipator lever nearer to the taller setting. Do this by one calibration mark.
Honeywell pneumatic thermostat:
Here’s how you can calibrate a Honeywell pneumatic thermostat:
Turn the setpoints down:
In the first step, make sure to turn the setpoint down by 5 degrees. Do this slowly. Then turn it back up slowly by 5 degrees. Notice if it bleeds off between 1 and 3 degrees. If so, then you will not need to calibrate.
Remove the cover:
Remove the cover of the thermostat. Add a 30 psi gauge to the tap. Now move the temperature setpoint indicator to the temperature again.
Turn the screw:
Now you will need to turn the calibration screw. Keep on doing so until the gauge reads 0 psi.
Honeywell mercury thermostat:
Here’s how you can calibrate a Honeywell mercury thermostat:
Stabilize mercury:
You will first need to stabilize the mercury. Then take a measurement in both the thermometer and the thermostat. If the variation is more than a degree, then you will need to clean the device.
Clean the thermostat:
Now you will need to clean the thermostat. Remove the cover of the thermostat for this step.
If the Honeywell mercury thermostat has its mercury vial inside, make sure that you use a level in order to ensure that the device is straight.
Honeywell ProSeries thermostat
Here’s how you can calibrate a Honeywell ProSeries thermostat:
Tap the menu button:
Tap the menu button and choose the Preference option. Further press the Advanced Preference option. Now press the next button, and keep on doing this until you find the “indoor display option.”
Adjust the temperature offset:
Now you will need to use the up and down buttons in order to set the indoor temperature offset. Press “Done” once you have completed the step.
Honeywell non-programmable thermostat:
If you’re trying to calibrate a programmable thermostat, you will need to follow these steps:
Remove the cover of the thermostat:
For the first step, you will need to remove the cover of the Honeywell non-programmable thermostat.
Make sure that the subbase of the device is mounted level on the wall. If you can’t ensure that, the mercury switch inside the device will not work accurately.
Jiggle the base:
Now jiggle the base of the thermostat until it is level. Now you will need to tighten the screws to the wall using a screwdriver.
Let a thermometer sit near the thermostat for 20 minutes, and it will soon display an accurate reading.
Can a digital thermostat be calibrated?
Yes, you can calibrate a digital thermostat. In fact, it is recommended that you calibrate the digital thermostat to the correct temperature in order to get accurate readings.
The digital thermostats come with newer technology. You can simply preset the digital thermostats to automatically make the necessary adjustments whenever there is a deviation in temperature. This process will help you save a lot of energy as well.
The calibration process involves two major steps. You will first need to identify how far off the temperature of the thermostat is from the real room temperature that day.
Then you will need to set the temperature of the thermostat offset parameter to account for the difference.
2 reasons why calibrate a Honeywell thermostat
Calibrating a thermostat is essential. You will need to pay special attention to its calibration in order to ensure accurate measurement and good performance. Calibrating a Honeywell thermostat is quite simple if you can follow the steps right.
Here are two reasons why you should calibrate a Honeywell thermostat:
Accuracy:
Calibrating your Honeywell thermostat will help you get accurate readings. It is likely that your thermostat gives off a reading that is deviated from the room temperature.
In such a case, calibrating will help. You can get accurate readings after calibrating the Honeywell thermostat.
Ensuring comfort:
If you do not calibrate your thermostat regularly, it is most likely that your room will seem cooler or warmer than the actual room temperature.
So in that case, the thermostat ends up being unproductive. If you want to ensure comfort in your home, you should calibrate your thermostat.
Final Thoughts
Calibrating the Honeywell thermostat is quick and simple. These thermostats come with different features and in different models. Each model has its particular manual for calibration. But generally, you will first need to identify the deviation in temperature and then account for the change.
