necessary to resolve an operating issue, a hex file
in a zipped folder will be provided. Save the
zipped folder to the computer’s desktop. Right

create another folder by the same name on the
computer’s desktop. Inside this folder will be the
hex file. It should be about 2300 KB. In the MCS-

Watch the chiller LCD screen. After the file is
uploaded, the FWCD unit controller will verify
that it’s a valid file and then erase the flash
memory. Next, it will write the new hex to
memory. When completed, the controller will
reboot itself. This process may take 15 or 20
minutes. After the reboot is completed, close and
restart the MCS-CONNECT software to
reestablish communication with the chiller.
