Wiring Setup
Refer to Figure 63 for a pictorial description of how to
connect the Cascade system together.
Master Boiler
The following needs to be done to the Master Text Display:
1) Connect the “To 848MN control” connector to the
DynaMax Ignition Control Board (848-MN). This
step was done by Camus unless the display was
disconnected in the field.
2) Place Switch to the “ON” position
3) Connect the “To next display” connector. This
connector serves as the communication point to the
next boiler. The “To previous display” connector is
to be left empty (no connection required)

b. Wire system sensor into system sensor input
Slave Boiler
The following needs to be done to the Slave Text Display:
4) Connect the “To 848MN control” connector to the
DynaMax Ignition Control Board (848-MN). This
step is done by Camus unless the display was

6) Connect the “To previous display” connector using
the connector from step 3.
If there are more than 2 boilers (up to 8) continue
