8.D.4.b.1 Rotation Setup
For Recurrence Mode, there are two parameters:
1.
Time of Day. You can adjust the hour and minute
of the day for rotation.
2. Every X Days . You can select how many days you
want to wait until rotation, and then it will rotate at
the hour and minute of the day previously selected.
There are two options for cascade Rotation Setup, Rotation ‘Mode’:
1.
Run Time
2. Recurrence
In the Run Time
Mode, you can adjust only the
Rotation Run Time Hours. This chooses which
unit will fire first based on run time hours.

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 all ignite, controlling to the ‘Lost Lead Backup Set Point’ without an external call for heat. This mode of operation
will continue until communication with the
lead unit is restored or until this mode is
turned off by pressing the ‘Release Demand’
button on the Cascade Parameters screen.
• Redundant Lead – In a cascade
configuration, upon loss of communication
with the lead unit, a second unit will assume
lead responsibilities. This requires the 2nd
lead to have a manual address of 2 and a
2nd system sensor installed at that unit.
• Disable Redundancy – In a cascade
configuration, upon loss of communication
with the lead unit, lag units will no longer
satisfy the cascade heat demand.
8.D.5
Hybrid
NOTE: The redundant lead unit should have a system sensor and be connected to the system pump (if / where
applicable). If the lead boiler maintains communication with the lag units, but loses connectivity with the system sensor,
the cascaded units will run at the calculated set point (CSP) provided by the lead unit, but will control to their individual
outlet sensor. In this mode, the temperature can be limited using the Backup Mode Max Lag Power parameter.
