Redundancy
To navigate to the Cascade Redundancy Screen, touch the Cascade Icon on the Configuration Screen, then touch the
Redundancy Icon on the Cascade Configuration Screen.
The Cascade Redundancy Screen allows the selection of one of three options for redundancy in cascade systems.
These options are:
• Boiler Internal Set Point – In a cascade configuration, upon loss of communication with the lead unit, the lag units
will continue to operate in the same manner as when the communication stopped. For example, if a lag unit was
firing to satisfy a cascade heat demand, it will continue to satisfy the heat demand upon loss of communication with
the Leader.
• Redundant Lead – In a cascade configuration, upon loss of communication with the lead unit, a second unit will
assume lead responsibilities.
• Disable Redundancy – In a cascade configuration, upon loss of communication with the lead unit, lag units will no
longer satisfy the cascade heat demand.
