    Every once in a while, your Honeywell Thermostat might glitch, crash, or freeze. Thankfully, a Honeywell thermostat reset is completely solvable.

    As long as your home environment is powered by Honeywell, and you are aware of your home’s model, you can reset any hanging software without breaking a sweat.

    Read on to find out how to rest a Honeywell Thermostat (all common models).

    It is important to note that, for some of the older Honeywell thermostats, a factory reset entails removing the unit.

    Only engage in this if you are knowledgeable about household and thermostat wiring systems. There is a risk of electric shock if this kind of reset is done carelessly. 

    In case one doesn’t have any experience with household thermostat wiring mechanisms, it is strongly recommended that they hire a qualified HVAC expert to conduct the factory reset.

    Before performing a reset of a Honeywell thermostat, it is recommended that you confirm which model the thermostat is. This information is found either at the bottom of the model or inscribed on the side. 

    Before we get to the simple step-by-step methods of resetting a Honeywell Thermostat, it is important to know that there are three different methods of resetting.

    These are factory reset, schedule reset, and Wi-Fi reset.

    • Conclusion

    Factory reset

    This type of reset shall restore the thermostat’s original factory settings, basically returning the unit to the original model when new.

    Most of the time, Honeywell thermostat owners carry this one out and it solves all their problems.

    Schedule reset

    Note that this type of reset only works with programmable Honeywell thermostats.

    A schedule reset removes all the scheduled functions that have been programmed into your thermostat.

    Wi-Fi reset

    A Wi-Fi reset clears the thermostat’s network memory.

    This type of reset allows the owner to set up a new connection or correct any connectivity issues that may be causing the thermostat to hang, glitch, or crash.

    How to conduct various Honeywell thermostat resets

    1. Honeywell Pro 1000 and 2000 Series/Battery-powered Honeywell thermostats

    These older models require a factory reset. The process is a bit convoluted, but it is quite simple:

    1. Turn the thermostat off by flipping the control switch located at the bottom of the unit to the center.
    2. Go to the breaker box of your home and shut off the power to the circuit that controls your Honeywell thermostat. In case you are unsure which circuit this is, you have to disable your house’s power temporarily.
    3. Lift the thermostat from the way, by lifting it from its mounting plate gently but firmly.
    4. Remove the batteries from the unit and return them the wrong way around (positive to negative and vice versa).
    5. Give the machine ten seconds or so to effect the changes.
    6. Remove the batteries and reinsert them the correct way around.
    7. Return the unit to the wall mount, and then restore power to the circuit (or the home), and then turn the Honeywell thermostat back on.
