Field Adjustability: Features adjustable start point and span settings to tailor actuator response to specific proportional control requirements

single-probe electrode holder engineered for high-pressure conductivity-based liquid level control

Built for durability in high-performance HVAC systems

Low ambient kits using these switches are designed for systems with expansion valve (TXV) metering devices to prevent liquid migration

Precise Thermal Calibration: Fixed 130°F cut-out and 110°F cut-in (L130-20F) provides reliable overheat protection

Trane CNT7507 Control Board Assembly Refrigerant Field Adjustability: Features adjustable startThe Trane CNT7507 Control Board Assembly is a high precision OEM refrigerant metering controller designed to manage the Electronic Expansion Valve (EEV) within compatible Trane and American Standard HVAC systems. As a direct factory replacement for legacy part numbers CNT06554, CNT06188, and CNT7054, this assembly is critical for maintaining accurate superheat levels and optimizing refrigerant flow. By utilizing advanced stepper motor control logic,
