62 WGZ030D through WGZ200D OMM 1130-2
Refrigerant type is factory-set.
BAS interface settings, available mid-2003.
The pressure offsets on menus 11 and 12 and the temperature offsets on menus 10, 11 and 12 correct the
controller's display of the parameters. The sensors used in these units have a high degree of repeatability
but may need correction (offset). An accurate pressure gauge or thermometer is used to determine the
correct temperature or pressure. A positive or negative offset value is then entered to make the controller
reading agree with the measured value.
