Wiring Diagrams

The control panel on POWER PLUS models 50 M, 100 M and 100 M DEP contains one master board and one or two slave
boards, depending on the output of the boiler. Models 100 S and 100 S DEP contain just two slave boards. If connecting a
series of boilers in cascading, the master board on the POWER PLUS 50 M, 100 M or 100 M DEP manages all the boards
on the POWER PLUS 100 S or 100 S DEP boilers via BUS.
