Compatible System and Applications
The MCX20B2 can be used in programmable refrigeration and HVAC/R equipment requiring extensive input and output capacity. Typical applications may include compressor racks, chillers, heat pumps, rooftop units, air-handling systems, industrial cooling equipment and custom OEM refrigeration systems.
Application software and parameter configuration are normally created for the original machine. The replacement controller must therefore be checked for compatible software, I/O allocation, communication settings and electrical connections.
Maintenance and Replacement Notes
Before replacing an installed controller, confirm the complete order number 080G0330, model MCX20B2, supply voltage, firmware or BIOS version, application software, input and output assignments, communication network and connector arrangement.
A controller with the same MCX20B2 family name may not operate correctly if it contains different application software or hardware configuration. Existing programs and parameters should be backed up whenever the installed system allows it.
