The number of Modbus Comm errors allowed
before invoking a Modbus comm fault (1 to 9).
The number of comm errors on ports 1 - 8.
The number of comm errors on ports 9 – 16..
The Client/Client Device address (0 to 250).
Choose either Points or Degrees.
Time & Date Sync Over
BST
If Enabled, the unit will synchronize time and date
with the BST Manager.
The minimum number of units in the BST cascade
(1 to 16).
The maximum number of units in the BST cascade
(1 to 16).
Specifies the time the BST Manager must wait for a
backup Client unit to turn on (15 – 300).
Main Menu → Advanced Setup → BST Cascade → BST Application Configuration
The BST Cascade’s application, either SH or Other.
SH Operating Mode
Other Operating Mode
The BST Cascade’s operating mode, Constant Setpoint.
SH Setpoint
Other Setpoint
The BST Cascade’s Setpoint (Operating Mode = Constant
Setpoint).
The current reading of the outdoor temperature sensor.
The threshold outside temperature above which the unit shuts
down (30 to 120 °F).
Main Menu → Advanced Setup → BST Cascade → Operating Controls
Main Menu → Advanced Setup → BST Cascade → Operating Controls → Sequencing Controls
Choose Off, On - Outlet Temp or On - Avg Temp. If either
“On” option is chosen, and BST detect a “low-flow” condition, it
slowly shuts down one unit at a time in an attempt to raise the
Fire Rate of the remaining units.
Specifies the valve position below which the plant enters this
mode (10% to 35%).
The valve position that triggers the next unit to come on line
(16% to 100%).
The valve position that triggers the next unit to go off line (16%
to 100%).
The maximum number of units that will fire (1 to 16, Unit Mode
in Cascade Configuration = BST Manager).
The time an open Isolation Valve will remain open once a unit
cycles off (0 to 15 min., Unit Mode = BST Manager).
Controls the frequency of updates made to the Fire Rate sent to
all units.
Specifies the firing rate above which the swing boiler will be
requested to support the DHW loop application (55 to 90).
Main Menu → Advanced Setup → BST Cascade → Operating Controls → Anti-Cycling Control
Minimum length of time a unit must stay off after shutting
down/going standby (30 to 300 sec.).
Once enabled, if the unit runs at a fire rate above Off Delay
Threshold and then shuts down, the fire rate will be reduced
to the Stop Level for a period of time defined in Off Delay.
Specifies the amount of time full shut down will be delayed (0 to
9999 sec., Slow Shutdown = Enabled).
The threshold fire rate above which Slow Shutdown will take
effect (40% to 100%, Slow Shutdown = Enabled).
The temperature above setpoint the unit may rise to during
delay shutdown (0°F to 25°F).
Offset temperature from setpoint before a unit may come online
(0°F to 25°F).
