Introduction
The Emerson F145-1328 Indoor Remote Sensor is designed to enhance the temperature monitoring capabilities of compatible Emerson Blue and White-Rodgers thermostats. This wired sensor provides accurate indoor temperature readings from a location separate from the main thermostat, allowing for improved climate control within your space.
Safety Information
- Always disconnect power to the thermostat and HVAC system before installation or servicing to prevent electrical shock.
- Ensure all wiring connections are secure and comply with local electrical codes.
- Do not install the sensor in locations exposed to direct sunlight, drafts, or near heat-generating appliances, as this can affect temperature accuracy.
- Keep the device dry and away from moisture.

Setup and Installation
1. Compatibility
This remote sensor is compatible with Emerson Blue and White-Rodgers thermostats that feature a wired indoor remote sensor option. Refer to your thermostat's manual to confirm compatibility.
2. Sensor Placement
Select a suitable location for the sensor that accurately represents the temperature of the area you wish to monitor. Avoid placing the sensor:
- Near windows or doors where drafts may occur.
- In direct sunlight.
- Near heat sources such as lamps, televisions, or heating vents.
- On exterior walls.
The maximum recommended distance from the thermostat is 300 feet (approximately 91 meters). For optimal performance, keep the wiring run as direct as possible.

3. Wiring Instructions
The F145-1328 is a wired sensor and typically requires three wires for connection to the compatible thermostat. Consult your thermostat's installation manual for specific wiring terminal designations (e.g., S1, S2, S3 or similar). The sensor connects to these dedicated remote sensor terminals.
- Power Off: Before beginning, turn off power to your HVAC system at the circuit breaker.
- Access Thermostat Wiring: Carefully remove the cover of your thermostat to access the wiring terminals.
- Connect Wires: Connect the three wires from the remote sensor to the corresponding remote sensor terminals on your thermostat. Ensure connections are tight.
- Mount Sensor: Secure the remote sensor to the wall using the provided mounting hardware.
- Restore Power: Once all connections are secure and the sensor is mounted, restore power to your HVAC system.
- Configure Thermostat: Follow your thermostat's instructions to enable and configure the remote sensor. This may involve navigating through the thermostat's menu to select the remote sensor option.
Note: Wiring color codes may vary. Always refer to the wiring diagram provided with your specific thermostat model.
Operating Instructions
Once properly installed and configured, the F145-1328 remote sensor will automatically provide temperature data to your compatible Emerson or White-Rodgers thermostat. The thermostat will then use this digital signal for more precise temperature monitoring and control.
- Temperature Monitoring: The thermostat will display the temperature reported by the remote sensor, or an average if multiple sensors are used.
- Enhanced Accuracy: The digital signal from the sensor contributes to a more accurate and stable temperature reading compared to the thermostat's internal sensor alone, especially if the thermostat is in a less ideal location.
- System Response: The HVAC system will respond to the temperature data from the remote sensor, helping to maintain the desired climate in the monitored area.
Maintenance
The Emerson F145-1328 Indoor Remote Sensor requires minimal maintenance.
- Cleaning: Periodically wipe the exterior of the sensor with a soft, dry cloth to remove dust. Do not use liquid cleaners or abrasive materials.
- Obstruction Check: Ensure that the sensor is not obstructed by furniture, curtains, or other objects that could block airflow and affect temperature readings.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not detected by thermostat. | Incorrect wiring, loose connections, thermostat not configured for remote sensor, incompatible thermostat. |
|
| Inaccurate temperature readings. | Improper sensor placement (direct sunlight, drafts, heat sources), sensor malfunction. |
|
| Intermittent readings. | Loose wiring connections, excessive wire length, electrical interference. |
