Setup and Installation

Before beginning installation, ensure the power to your HVAC system is turned off at the circuit breaker to prevent electrical shock.

Mounting the Thermostat

The Honeywell Home UWP wall plate is included to facilitate an easy installation process and simplify potential future device upgrades. Secure the wall plate to the wall using the provided screws and anchors. Ensure the plate is level before tightening.

  • Press the MODE button on the left side to cycle through available operating modes: Cool, Heat, and Off.

Fan Operation

  • Press the FAN button on the left side to select fan operation: Auto (fan runs only when heating or cooling is active) or On (fan runs continuously).

Maintenance

Change Filter Reminders

The thermostat can be customized to provide reminders for changing your air filter. Consult the full installation guide for instructions on how to enable and set these reminders.

Cleaning the Thermostat

To clean the thermostat, gently wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or internal components.

Battery Replacement

When the battery indicator appears on the display, replace the two AA batteries promptly to ensure continuous operation. Refer to the 'Battery Installation' section for instructions.

Troubleshooting

If you experience issues with your thermostat, consider the following common solutions:

  • No Display or Power: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary. Ensure the circuit breaker for your HVAC system is on.
  • System Not Responding: Verify that the thermostat is set to the correct mode (Heat or Cool) and that the temperature setting is above (for cooling) or below (for heating) the current room temperature. Check all wiring connections at the thermostat and the HVAC system.
  • Inaccurate Temperature Reading: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its temperature sensor.
  • Fan Not Operating: Check the FAN setting. If set to 'Auto', the fan will only run when heating or cooling is active. Set to 'On' for continuous fan operation.
  • Compatibility Issues: Confirm your HVAC system is a single-stage 1 Heat/1 Cool system. This thermostat is not compatible with multi-stage systems or 120-240V electric baseboard heating.

For persistent issues, contact a qualified HVAC technician or Honeywell Home customer support.
