York 031-02742-000 Controller

The York 031-02742-000 Drain/Feed Controller is a high-precision HVAC replacement part engineered for demanding liquid level management in commercial and industrial chillers. Often identified as an AK2-XM Stepper Module, this component provides the critical 0-10 VDC control signal interface required to drive electronic expansion valves (EEV). Unlike legacy controllers, the 031-02742-000 is specifically balanced for use with the ETS series stepper valves, ensuring linear flow response and optimized superheat control. For technicians performing a York chiller repair, this module serves as a direct replacement for 080Z0147, maintaining seamless integration with the existing building automation network and 35 VDC power supplies. The unit features real-time monitoring capabilities to prevent system overflow or underflow, protecting the compressor from liquid slugging while maximizing evaporator efficiency. Its rugged PCB design is tailored for the high-vibration environment of a mechanical room, providing reliable stepper motor control and precise drain/feed regulation across a wide operating temperature range.

• Precise EEV Control: Specifically calibrated for ETS stepper motor valves to ensure accurate refrigerant metering.
• Direct OEM Integration: Seamlessly replaces York part number 031-02742-000 and Danfoss 080Z0147 without additional wiring modifications.
• Optimized Efficiency: Features advanced algorithms that prevent underflow/overflow, protecting critical HVACR system components.
• Rugged Construction: Designed to withstand the electrical noise and thermal fluctuations common in industrial chiller panels.

Is this controller compatible with older KVS series valves?
No, the 031-02742-000 is optimized for the analog input required by newer ETS series valves. If you are replacing an obsolete KVS valve with an ETS valve, this controller is necessary to ensure the stepper motor operates correctly.

What are the power requirements for this module?
This York power controller typically operates off a 35 VDC source, which can be daisy-chained from the original controller power supply in multi-valve configurations.

Does this unit require specialized programming?
While the hardware integrates directly, field calibration should be performed by a qualified HVAC technician to match the specific drain/feed parameters of the chiller unit.
