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).
- Product Dimensions (WxDxH): 3.12 w x 0.88 x 3.12 in.

I really like these simple to use non complicated thermostats. I would like them even better if they did not have an off position for millivolt use.

Soooooo glad to get the correct part for my ancient floor furnace. Everyone , box store Pros swore the 24V to millivolt would work. I researched what I needed on the Honeywell site, had it shipped to my home, installed it and we have a happy Warm house again. Thanks Honeywell !
