INTRODUCTION
The AM Series Cascade Sequencer controller is used to control a cascade arrangement of up
to eight (8) AM Series water heaters or boilers. This document provides instructions for
installation and operation of the cascade sequencer.
Please note that the cascade sequencer requires a communications board be installed in
each AM Series boiler or water heater. This board is present in every AM 500, 750, and
1000 but is an option on the AM 399 and must be installed prior to cascade sequencer
installation. For further information see the AM Series Modbus installation Guide (TID-0123).
