Danfoss 080G0066 MCX06C Programmable HVAC/R Controller

Product Overview

The Danfoss 080G0066 MCX06C is a compact programmable electronic controller developed for heating, ventilation, air-conditioning and refrigeration applications. Its panel-mount design, integrated LED display and flexible input/output configuration make it suitable for compact HVAC/R machines and control panels.

The controller operates from 24 VAC or 20–60 VDC power and provides six digital relay outputs. Communication capabilities include CANbus and Modbus RS485, allowing connection to other MCX controllers, remote interfaces and compatible building-management equipment.

The MCX06C is programmable hardware. The required application software, parameter set and machine configuration must be confirmed separately. The presence of the controller hardware does not guarantee that it contains the software required for a specific chiller, heat pump or refrigeration machine.

Technical Specifications

Compatible System and Applications

The MCX06C can be programmed for compact chillers, rooftop units, heat pumps, air-handling systems, refrigeration equipment, fan-coil systems and other HVAC/R machinery. Its actual control functions depend on the installed application software and I/O configuration.

Maintenance and Replacement Notes

Before replacing an existing controller, confirm the complete Danfoss reference 080G0066, MCX06C hardware type, supply voltage, connector arrangement, BIOS or hardware revision and installed software application.

A replacement MCX06C may require application download, parameter transfer and commissioning. Do not assume that a new or blank controller will operate the machine immediately after installation. Back up the original application and parameters whenever technically possible.
