Trane Baysens019c Manual

Trane BAYSENS019C is a widely used programmable zone sensor primarily designed for commercial HVAC systems like Constant Volume (CV) and Heat Pump (HP) units. It is highly regarded for its durability

($390–$425 approx.) because Trane’s communication protocol is proprietary.

Measure the resistance (ohms) across the sensor wires while they are disconnected from the board. At 25°C (77°F), the resistance should be exactly 10,000 ohms (10kΩ) Error Codes:
