White-Rodgers F145-1328 Remote Sensor

The White-Rodgers F145-1328 Remote Sensor is a critical component for contractors looking to optimize space-averaging or remote temperature monitoring in residential and light commercial applications. This wired indoor sensor communicates via a digital signal, which eliminates the common issue of temperature variance caused by wire resistance—a frequent headache with older analog thermistors. As a veteran-grade accessory, it is fully compatible with White-Rodgers ComfortSet thermostats and the wider Emerson Blue series, specifically those equipped with indoor remote sensing capabilities like the 1F90, 1F95, and 1F97 series.

For high-performance installations, this sensor supports a maximum wire run of 300 feet from the subbase. To ensure signal integrity and reduce electromagnetic interference, it is recommended to use 20-gauge, 3-conductor shielded cable, especially when routing near high-voltage lines. The F145-1328 allows for temperature averaging by connecting up to three sensors to a single thermostat, providing a balanced thermal profile in multi-story or large open-plan layouts. Its unobtrusive, classic white design and compact 2-1/8" x 3-1/2" footprint make it an ideal choice for high-traffic areas where the main thermostat must be secured or hidden from public access.

• Eliminate Drift: Digital signal processing prevents voltage drops and resistance-related inaccuracies over long cable runs.
• System Flexibility: Compatible with all Emerson and White-Rodgers thermostats featuring remote indoor sensing terminals (S1, S2, S3 or +, S, -).
• Enhanced Comfort: Facilitates accurate room temperature averaging across multiple zones when combined with additional sensors.
• Tamper Prevention: Allows the main control to be mounted in a secure utility room while sensing the actual living or workspace temperature.
• Wide Operating Range: Precision monitoring across 40°F to 99°F ambient environments with 0-90% non-condensing humidity tolerance.

What wire should I use for the longest run?
For runs up to the 300-foot limit, use 20 AWG or 18 AWG 3-conductor shielded cable. Ensure the shield is grounded at the thermostat subbase only to prevent ground loops.

Can I use this sensor for outdoor temperature monitoring?
No, the F145-1328 is strictly an indoor model. For outdoor ambient sensing, you must use the F145-1378 model which includes the appropriate weather-sealed probe.

Does this sensor require batteries?
No, this is a hardwired digital sensor that draws power directly from the thermostat's remote sensor terminals.
