How do I use an old Honeywell thermostat?

Answered by Jeremy Urbaniak

To use an old Honeywell thermostat, there are a few steps you need to follow. First, locate the thermostat on your wall. It is usually found in a central location in your home, such as the hallway or living room. Once you have located the thermostat, you will see a display screen and several buttons.

To set the temperature on your Honeywell thermostat, you will need to press the up and down buttons. These buttons are typically labeled with arrows pointing in the respective directions. Press the up button to increase the temperature and the down button to decrease it.

When you press these buttons, you will see the temperature displayed on the screen change. Keep pressing the buttons until you reach your desired temperature. The temperature you set will stay until you change it again.

It is important to note that with an old manual thermostat, you do not have the option to program different temperature settings for different times of the day. This means that the temperature you set will remain constant until you manually adjust it.

If you want to turn off your heating or cooling system completely, you can do so by setting the temperature to a level that is outside the normal range for your home. For example, if you want to turn off the heat, you can set the temperature to a very high value, such as 90 degrees Fahrenheit. This will prevent the heating system from turning on.

Similarly, if you want to turn off the cooling system, you can set the temperature to a very low value, such as 40 degrees Fahrenheit. This will prevent the cooling system from turning on.

In addition to setting the temperature, some older Honeywell thermostats may have other buttons or switches that control additional features. These features could include fan control, system mode (heat, cool, or off), and hold/override functions.

To control the fan, look for a button labeled “Fan” or “Fan Control.” Pressing this button will cycle through different fan settings, such as “Auto” or “On.” The “Auto” setting means that the fan will only run when the heating or cooling system is actively running. The “On” setting means that the fan will run continuously, even when the heating or cooling system is not actively running.

To change the system mode, look for a switch or button labeled “Heat,” “Cool,” or “Off.” This will allow you to switch between heating mode, cooling mode, or turning off the system completely.

Lastly, some older Honeywell thermostats may have a hold/override function. This function allows you to temporarily override the programmed temperature settings. For example, if you have programmed your thermostat to maintain a certain temperature during the day, but you want to temporarily increase or decrease the temperature, you can use the hold/override function. Look for a button labeled “Hold” or “Override” and press it to activate this feature. Once activated, you can manually adjust the temperature as desired. The hold/override function will remain active until you manually turn it off or until the next programmed temperature change.

Using an old Honeywell thermostat is relatively simple. Locate the thermostat, set the temperature using the up and down buttons, and utilize any additional features such as fan control, system mode, and hold/override functions if available. Enjoy the comfort of your home with your manually controlled thermostat.
