Trane WIR2957 Wire R-22 Professional-grade construction guarantees reliable communication

Professional-grade construction guarantees reliable communication between the thermostat and mechanical hardware under demanding environmental conditions

Normally Open Configuration: Ensures the valve remains in the open position upon loss of control signal

The D0R configuration is typically used in control schemes where the reset logic is handled by the primary burner control or through the wiring of the SPDT contacts

Systems with scroll compressors generally do not require supplemental start components unless specified by local codes

specifically for 40-gallon and 50-gallon high-recovery models

Trane WIR2957 Wire R-22 Professional-grade construction guarantees reliable communicationTransitioning to integrated control systems requires precise connectivity, and the Trane WIR2957 (also identified as WIR02957) is the specified 5 pin wire harness for interfacing with ICM motor assemblies. This genuine OEM component is engineered to facilitate reliable communication between the system control board and the condenser fan motor, ensuring the high voltage signals required for varying motor speeds are delivered without impedance.
