Com6000 Upo Mode; Com6700 Upo Mode - Garland MCO-GD-10M Service Manual

The User Preference Offset is designed to enable the user to adjust the controlling temperature. There are two
different styles of controllers used by GARLAND at the present time. They are the Robertshaw COM6000 and
COM6700 Series. To determine which of the controllers you are working on, look at the back of the controller and you
will see a sticker with a printed number like "PN:100-289-03", below this number is the controller style number. For
example: COMA-6704-GL. This indicates that controller is in the COM6700 Series. Or if the number was "COM-
6000-GA" it would indicate that it is a COM 6000.
