Product Overview
The Danfoss 080G0251 MCX061V is an advanced programmable HVAC/R controller with an integrated electronic expansion valve driver. It is designed for refrigeration, chiller and heat-pump applications requiring coordinated compressor, fan, valve and system control.
This 24 VAC version includes a graphic LCD display, CANbus communication, Modbus RS485, seven analog inputs, eight digital inputs, three analog outputs and eight digital outputs, including six relay outputs.
The integrated EXV driver is a major functional difference from standard MCX06C and MCX06D controllers. The valve type, stepper-motor parameters and application software must be matched to the installed refrigeration system.

Compatible System and Applications
The MCX061V is suitable for chillers, heat pumps, condensing units, refrigeration systems and other HVAC/R equipment using an electronically controlled expansion valve. The exact function depends on the loaded control application and valve configuration.
Maintenance and Replacement Notes
Confirm the valve-driver requirement, valve type, supply voltage, software application, controller BIOS and I/O wiring before replacement. Incorrect valve parameters may cause unstable superheat control or valve-operation faults.
The 080G0251 does not include Ethernet. If Ethernet and SD-card functions are required, compare the 080G0255 configuration. Do not assume that MCX061V variants with different 080G references are interchangeable.
Related Models
Related models include 080G0250 MCX061V for 110–230 VAC, 080G0255 MCX061V with Ethernet, 080G0112 MCX06D and 080G0284/080G0285 high-I/O MCX valve-controller versions.
Inquiry and Supply Notes
Please provide reference 080G0251, the electronic expansion valve model, machine type and photographs of the original controller label. Confirm whether software programming and parameter transfer are required.
