How do I reset my Honeywell Thermostat?

There isn't a universal reset for all Honeywell Non-Programmable Thermostats. The process will vary depending on the specific thermostat. However, here are the two most common methods:

Method 1: Power Cycle Reset

  • Turn off the power: This can be done by flipping the breaker that controls your HVAC system, or by removing the batteries from the thermostat (if battery-powered).
  • Hold the reset button (if present): Some non-programmable Honeywell Thermostats have a dedicated reset button, usually located near the display or behind a cover panel. If your model has one, hold it down for about 5-10 seconds while the power is off.
  • Restore power: Turn the breaker back on or reinsert the batteries.

Method 2: Menu Reset (for some models)

  • Check your thermostat for a "Menu" button. Not all Honeywell Non-Programmable Thermostats will have one.
  • If present, press and hold the "Menu" button. While holding it, navigate through the options (if any) until you find a "Reset" function. This might involve pressing arrow buttons.
  • Select "Reset" and confirm the prompt (if applicable).
