How To Clear Schedule On Honeywell Thermostat: Series 2000 – 9000 Models

Honeywell Thermostat 1 Lg

The thermostat in your home has a vital function: controlling the heating, cooling, and ventilation to keep you and your family comfortable. If the thermostat is not functioning optimally, it can make your home uncomfortable. Your home could be too hot, too cold, or lacking in ventilation, and it can increase your energy costs. Now and then, you need to give your thermostat some attention to keep it functioning according to your needs.

To clear the program schedule on your Honeywell Thermostat, press the “Hold” button. For all scheduled periods, this will overrule the set temperature. The programmed schedule is cleared when you hold down the Hold button, and you will be prompted to enter a new temperature setting for the thermostat.

Clearing the schedule on programmable Honeywell thermostats is not a complex process. In the more advanced models, there are a few simple keystrokes on the menu. The process is slightly more in-depth on the less advanced models and may require a factory reset to clear the schedule.

Honeywell is a trusted brand of thermostats with a reputation for well-made, easy-to-use products to control and adjust the heating and cooling in your home. When the heating and cooling is not optimal in your home, your thermostat may need some adjusting. It is unnecessary to call out a technician or a professional to sort these kinds of issues out. With a bit of essential guidance, you can resolve most of these thermostat issues yourself.

How Do I Clear My Honeywell Thermostat Settings?

If your thermostat is not functioning optimally, you may need to clear the schedule completely by completing a factory reset on the thermostat, or you may want to bypass the schedule temporarily to adjust the temperature from the schedule to something more comfortable.

Some smart models will have menu items to select the schedule from the menu and then clear the schedules to implement a new schedule. However, if you are having some trouble with your thermostat’s programming, you may need to perform a factory reset.

Warning: Some thermostats connect directly to the main electrical supply of the house. It would be best to always switch off the main electrical power at the circuit breaker before working on these units. If you are unsure which Honeywell thermostat model you have, consult an HVAC professional for assistance.

The 2000 series of Honeywell thermostats are fairly basic units. This series does not come with a menu option to clear the schedule for the thermostat.

The 2000 series comes pre-programmed with Energy Star settings that are efficient, cost-saving recommended settings. Once the unit is back to factory settings, you can adjust the schedule to your liking.

Why You Need To Reset The Schedule On Your Honeywell Thermostat

Over time, this program loses efficiency, and things get out of sync, resulting in the controller program not operating at maximum efficiency. You will notice this when the thermostat does not respond by giving you the temperature you have set at the correct time that you programmed in the schedule on the thermostat.

The thermostat controller on the wall in your home is not the actual thermostat; it is the controller. This controller is like the junction box that receives information from sensors in your home and then tells the thermostat what to do according to the data it receives from the sensors.

The controller also considers the temperature schedules that have been put into the controller for specific times of day and seasons.

Management of the environmental information and decision-making regarding adjusting the environment in your home is controlled through the built-in computer program in the thermostat controller.

When you notice these discrepancies in the performance of the thermostat controller, it is a good idea to reset the schedule on your thermostat. This process will clear the schedule, free up storage space for the program, and re-organize it to its original state.

Are All Honeywell Thermostats Programmable?

Not all Honeywell thermostats are programmable to set up personal schedules for the heating and cooling of your home. The programmable thermostats will have more controls and will have menu options on the screen. Non-programmable thermostats will have basic controls that will switch the unit off or on and adjust the temperature up or down.

You can also tell if your thermostat is programmable by the model number of the unit. The location of the unit’s model number is on the rear of the thermostat. It is either on the backing plate or behind the battery pack. The unit’s model number is preceded by the letters TH, T, RTH, RCHT, CT, TL, or RLV, which are a designation of the model range of the unit.


Clearing the schedule on a Honeywell thermostat is not difficult, but the procedure does differ from model to model. It is essential to establish which model that you have so that you can follow the correct process.

Some units are connected directly to the mains electricity of the house. This potential danger requires an extra measure of caution when working with these units.

If you doubt the thermostat model and your ability to successfully and safely change the schedule, call out a qualified HVAC professional to do it for you.
