White-rodgers 1451378 Wired Outdoor Remote Temperature Sensor

Product Description

The WHITE-RODGERS 1451378 is a wired outdoor remote temperature sensor designed to work with compatible Blue Series thermostats. It extends the thermostat's ability to monitor outdoor ambient conditions by placing a remote sensing element outside the conditioned space. The sensor connects via a 12-foot sensor lead and supports wire runs up to 300 feet from the thermostat using 20-gauge, 3-conductor cable. Overall dimensions measure 2.13 inches H x 3.50 inches W x 0.75 inches D. The classic white housing is suited for both indoor and outdoor mounting locations. HVAC technicians install this sensor during thermostat commissioning or as a field add-on to enable outdoor temperature display and dual-fuel or code-compliant control strategies.

This sensor is applicable to residential and light commercial HVAC installations where the thermostat requires outdoor temperature input. It is listed as compatible with Blue Series 12-inch and 6-inch thermostats from WHITE-RODGERS. It is also noted for use with the WR1F950671 NC code compliant thermostat and in dual-fuel system applications where outdoor temperature lockout logic is required. The sensor supports system control decisions based on measured outdoor conditions, making it a functional component in heat pump and dual-fuel setups.

Designed for use with WHITE-RODGERS Blue Series 12-inch and 6-inch thermostats, including the WR1F950671 NC code compliant thermostat. Also suited for dual-fuel system applications requiring outdoor temperature sensing input.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the thermostat and HVAC system at the breaker before making any wiring connections. Use 20-gauge, 3-conductor cable for field wiring runs and keep total wire length within the 300-foot maximum. Mount the sensor in a location sheltered from direct sunlight and precipitation to ensure accurate ambient temperature readings.
