How to Turn Off Honeywell Thermostat

12. Dezember 2021 | Air Conditioner

Not only do Honeywell programmable thermostats improve our lives, but they may also aid us to save cash on our air – conditioning expenses. However, when the climate is so nice outdoors, you really want to connect with the world and let the cool air in. As a result, you may switch off the Honeywell thermostat to avoid the ac unit or heater from turning on needlessly.

Step 1:

Remove the smart thermostat’s lid.

Step 2:

Recognize the various controls. The blower should include a switch that enables either automated or human operation. There are also controls for adjusting the central heating routines and a muti switch marked cooling, warming, including off.

Step 3:

Place the conditioning, warming, and off lever on the button in the off state. With most variants, the middle position on the lever is labeled „off,“ but verify the particular model’s marking to see which is appropriate.

Step 4: 

Remove the Honeywell thermostat’s lid. Simply raise the lid and slide the slider across to the chosen position to continue utilizing the programmed cooling or heating routine. The programmed thermostat’s parameters will be followed by the heater or ac unit yet again.

Troubleshooting Honeywell Thermostat:

How to Turn Off Honeywell Thermostat Problem Solving

You’re simply dealing with another one of three situations if your thermostats fan won’t be turning off: 

The Honeywell Thermostat airflow relay is set to „manual override.“ As the fan relay is damaged or an issue with the cabling in the thermostat, this should be replaced.

Honeywell Thermostats cause issues due to:

  • Sensors that are malfunctioning.
  • Temperatures that are too hot or too cold.
  • The airflow limit control on the Honeywell thermostat is configured to be manual.
  • Thermostat Controls.
  • The motor select button on the thermostat is configured to manual.

Reset the Thermostat:

Let’s begin by performing a fast restart on the Honeywell unit to see if it brings the thermostat back to life.

You may disable the thermostat by pressing the „Off“ button.

Place a little nickel item in the gap to open the cell door.

Unplug the cells from the apparatus.

Backward-install the cells such that the positive pole is aligned to the negative terminal.

In the device, change the cells in the right sequence.

Shut the cover to the battery box.

Check the Controls:

The fan control lever on Honeywell thermostats normally has two (occasionally three) configurations: Cooling, Automatic, and Circulate.

Make absolutely sure that your thermostat fan is turned to Automatic instead of On.

The On option turns on the blower and keeps it running indefinitely. If you choose this alternative, its fan will run regardless of whether the cold or hot settings are switched on.

Because when setting is adjusted to Automatic, the motor will operate in conjunction with the heating or air conditioning system whenever it is switched on.

But if any of the measurings is active, this function prohibits the blower from working. That would be the optimum setting since it conserves energy.

Lastly, the Circulation option allows its fan to turn on and off at a pace of around 20 minutes each hour.

It’s usually kept for seasons like spring and fall – when the indoor temperature doesn’t require any air conditioning.

As a consequence, if we set our thermostat to Always On instead of auto, your blower will run nonstop.

Adjusting Temperature of Honeywell Thermostat:

Returning to the variables mentioned above and how they may affect the Thermostat fan going off, we’ve included some instructions for changing the Thermostat parameters below:

It’s as easy as pushing the fan lever to switch between Automatic, On, and Circ. modes.

When you’ve found the setting you need, hit the switch to enable it.

Defective Sensors:

Due to a major faulty sensor, your Honeywell thermostat motor will not turn down.

Imagine this: if a sensor fails, your thermostat becomes practically blind.

Whenever a gauge can’t identify the interior temperature, it gives the computer inaccurate information. As a consequence, even though the fan isn’t required, your thermostat may well be instructed to leave it going.

You’ve found the heart of the issue if the ambient temperature indicated on the controller and the number on the thermometer disagree.

Faulty Wiring:

Most current thermostats include a separate connection for controlling the air. It’s dark green and attaches to a G connector on the rear of your thermostat.

Most modern thermostats need an additional C-wire, something that many house systems lack.

As a response, technicians commonly rewire the blower wire as that of the C-wire, keeping the G terminal unconnected. The machine will operate continually in this case since it is not controlled simply by the equipment.

Examine to see whether your device needs a C-wire to work.

If that’s the scenario, unscrew the thermostat’s lid to reveal the platform.

To repair the motor, you might have to change the cabling if there’s not a wire attached to the G connector.

Call a professional if the wire has to be replaced.

The White Button:

Verify the white button isn’t pushed.

The fan’s cutoff switch will have a little white button just in the lower corner. The key determines if the switch works mechanically or on auto.

The toggle is switched to Manual if the key is pushed in, or the motor is compelled to run continuously. As for the blower to operate correctly, you’ll have to set it to Automatic.

The Bottom Line:

We believe that the preceding techniques and actions have assisted you in resolving the issue, and that now you have a better understanding of why this problem happened.

Finally, there seem to be a few possible causes for your Honeywell thermostat fan not turning off. The major reason for this is because your thermostat is set to Being on, which means it will operate continuously, rather than Auto, which means it will only function at particular hours.

An even more technical problem is that the operation of your Selector switch is defective, and you’ll need to visit an expert about it.

FAQ – How to Turn Off Honeywell Thermostat

FAQ - Section

How do I turn on/off my heating/cooling on my TH2210DH/TH2110DH/TH2210DV/TH2110DV series thermostat?

There are three ways to turn on or off your heating/cooling on the TH22xxDH, TH21xxDH, TH22xxDV and TH21xxDV series thermostats: from the main screen, from the quick settings menu and from within a program.

From the Main Screen: To turn off your heating/cooling, press „OFF“ under „HEATING & COOLING.“ This will change the icon to an „X“ and turn off your system. To turn it back on, press „ON“ again. The same goes for turning up or down the temperature – just press „+“ or „-„.

From Quick Settings Menu: If you only want to make a temporary change, like turning off your cooling for a while, you can do it from the quick settings menu. Press „HOME“ and then use the arrow keys to scroll down to „QUICK SETTINGS.“ Select „HEATING & COOLING“ and then press „OFF“ or „+“ to turn it off or up.

From Within a Program: You can also turn your heating/cooling on or off within a program. Go to the program you want to edit and press „SELECT.“ Then use the arrow keys to scroll down to „SETPOINT SCHEDULE.“ Under that, there will be icons for heating, cooling, humidity control and fan. To turn off your system, just hit the icon for heating or cooling. This will change the icon to an „X“ and turn off your system.

To turn it back on, press the icon again to change back to a dot. You can also do this from within the program’s time settings menu by changing one of these four items – heating/cooling/humidity control or fan setting.

How to Change a Wall Thermostat Battery?

Changing the battery in your Honeywell thermostat is simple. You’ll need to use a small screwdriver or coin and insert it into the back of the cover slot to pry open the front panel.

Once you’ve removed that, pull out batteries with needle-nose pliers if they are still connected by metal clips, which will disconnect easily by pulling them apart. If there are no metal clips, simply remove one end from each other then disengage – this might take some gentle wiggling around as sometimes these can break pretty easily when removing from their housing, so you want to try not breaking them if possible. On most models, though, including all TH22DH/TH21xxDH thermostats, you can just pull them apart.

Once they are separated, then put in new batteries with the positive side facing up – it’s pretty obvious, but I have seen some people try to put these in backwards, so do note that if your unit is running low on power and not responding correctly, this may be why! Then snap the front cover back into place being careful not to pinch any wires or damage anything inside of your thermostat when closing over the opening again. That’s all there is to changing a Honeywell wall thermostat battery.

What’s the difference between run and hold on a Honeywell thermostat?

„HOLD“ will maintain the current temperature setting in your home without turning on or off your heating/cooling system. „RUN“ will turn on your heating/cooling to reach the setpoint that you have programmed.

If you are leaving for an extended period of time and do not want your heating or cooling running continuously, we suggest using the „hold“ function. This will keep your home at a comfortable temperature without any fluctuations while you’re away. If you only need to hold off temporarily, like when it’s really hot outside and you don’t want the AC running, then use the „off“ button under „heating & cooling.“ This will stop your system from reaching the setpoint until you turn it back on.

How do I override my Honeywell thermostat?

There are a few ways to override your Honeywell thermostat: from the quick settings menu, within a program or from the time settings menu.

To override your thermostat from the quick settings menu, press „HOME“ and then use the arrow keys to scroll down to „QUICK SETTINGS.“ Select „OVERRIDE SCHEDULE“ and hit „ENTER.“ This will bring up a list of current programs with an „X“ next to the one you want to override. To exit this screen without overriding anything, just press „ESC.“

If you want to override your thermostat within a program, go to the program you want to edit and press „SELECT“. Then use the arrow keys to scroll down to „SETPOINT SCHEDULE.“ Under that, there will be icons for heating, cooling, humidity control and fan. To turn off your system, just hit the icon for heating or cooling. This will change the icon to an „X“ and turn off your system.

To turn it back on, press the icon again to change back to a dot. You can also do this from within the program’s time settings menu by changing one of these four items – heating/cooling/humidity control or fan setting.

You can also override your thermostat by pressing „OFF“ under either „HEATING & COOLING“ or „HUMIDITY CONTROL.“
