To reset the Prostat PRS4110 thermostat and operate it like a regular thermostat without programs, follow these steps:
1. Reset the thermostat by gently pressing the reset button using a small object (like a toothpick or paperclip). The reset button is inside a small hole on the front of the thermostat labeled “reset.” This erases all user settings and programming.
2. After resetting, enter the User Options menu by holding down the RETURN button for about 3 seconds until the screen changes.
3. Use the arrow buttons to reach Option 1, which controls the programming mode.
4. Select “PRO NO” for Non-Programmable Mode.
5. Press RETURN to save the setting and exit. The thermostat will now operate without programmed schedules.
