Amnewid Batri

When the battery indicator appears on the display, replace the batteries promptly. The thermostat relies on battery power for its display and internal logic, and a depleted battery will prevent the unit from operating your HVAC system. To replace batteries, gently pull the thermostat unit away from its wall plate. Replace the old batteries with new ones (typically AAA), ensuring correct polarity. Reattach the thermostat to the wall plate.

• Temperature Swing Issues: If the thermostat is not maintaining a consistent temperature, you may need to adjust advanced settings. Access the advanced menu by sliding the MODE switch to OFF, pressing RUN to activate the backlight, then holding the RESET button (on the back) while pressing SET. Release both buttons within 5 seconds. From this menu, you can adjust settings like:
  • GWRTHOD: Calibrate the temperature reading if it consistently differs from other thermometers in the room.
  • MINIMUM CYCLE PERIOD: Adjust the minimum time the system runs to prevent short cycling. Setting it to six minutes or greater enables smart logic for improved performance.
  • MATH SYSTEM: Ensure this is correctly set for your furnace (F) or heat pump (HP).
• System Not Turning On/Off as Programmed: Verify your programming schedule. Check the MODE and FAN switches are set correctly. Ensure all wiring connections are secure.
