AprilAire 8051 Flush-Mount Temperature Sensor
AprilAire 8051 Flush-Mount Temperature Sensor
Remote indoor temperature sensing with a discreet flush-mount finish.
The AprilAire 8051 is a wired remote temperature sensor designed for installations where the sensing location should remain visually unobtrusive. The small flush-mount disk can be painted or wallpapered to better blend into the finished wall.
Depending on the connected AprilAire thermostat or support module, the remote temperature reading can be used for monitoring or as the active temperature input.
Key Features
- Flush-mount indoor design for minimal visual impact.
- 10 kOhm nominal temperature-sensing element.
- +/-3% published resistance tolerance.
- Maximum published sensor-wire length of 300 ft.
- Uses 18-24 gauge, 2-conductor or greater low-voltage wiring.
- Compatible with a range of AprilAire thermostats and legacy support modules; verify the exact control before ordering.
Application & Compatibility
Current AprilAire sensor documentation lists compatibility across selected 8600/8800/8900 and S86 controls, plus S84NSU. Legacy documentation also uses the 8051 with 8061/8062 support modules. Compatibility depends on the thermostat input architecture, so verify the exact target model.
