If the unit has the millivolt input bd.# 20229, A & B inputs can be
separately solder jumper programmed to accept either a low milli-
volt or 4-30 V input. Each unit shipped is programmed according
to part number. If solder jumpers are made, the part number
should be modified to reflect the changes made
