CHAPTER 2:
OPERATION
NOTE:
After turning on power, wait at least 40 seconds for communication between sequencer and
heaters to finish before performing any operations. Wait for the cascade manager to recognize
the address of the master boiler or water heater.
2.1 Cascade Sequencer Display and Controls
The AM Series Cascade Sequencer features a display and lower cover that is opened to reveal
a number of buttons, as shown in Figure 2-1. In the default display shown in Fig- 2-1, the icons
labeled "M" and "D" in the left display field represent the firing rate and current state of the
first and second burners in the master unit and are not important to the function of the
cascade manager. Similarly, the information field only refers to the Master boiler.
If the outdoor temperature sensor is not connected it will display a temperature of "-40".
Similarly, if the cascade temperature sensor is not connected it will display a temperature of
roughly 12 to 14 degrees.
