Addressing Modes
For communication in a multi-burner or multi-control environment, each MicroM must have a
unique address. The range of address allowed within the MicroM is 0 to 31 allowing for a possible 32
units to be connected in a single multi-drop node. As shipped the default address is 0. The address of
the MicroM may be set using two methods. Using the ED510 display, it is necessary is SCRL to the
PROGRAM SETUP menu and enter that submenu with the MODE key. SCRL down until the dis-
play indicates UNIT ADDRESS with the actual address of the MicroM being displayed on the top
line of the display. Pressing and releasing the RESET key will cause the address to increment. The
