(continued)
Description
• Lowest measured run time or
• Rotate in sequence order
• Lowest measured run time or
• Rotate in sequence order
Toggles lead boiler after this time has elapsed
Forces lead lag rotation
Until all boilers are firing - No boiler is requested to exceed the
common base load rate.
• Use error threshold to add stage or
• Do not add stage
Delay before adding a stage once temperature has dropped to setpoint
minus the error threshold.
Temperature drop below setpoint required before more stages are
added.
Minimum time after a stage is added before another stage can be added.
• Use error threshold to add stage or
• Do not add stage
Delay before dropping a stage once temperature has risen to setpoint
plus the error threshold.
Temperature rise above setpoint required before more stages are
dropped.
Minimum time after a stage is dropped before another stage can be
dropped.
• All boilers off at threshold (all boilers shut down at error threshold)
• Lead boiler off at threshold (only the lead boiler shuts down)
Temperature at which all boilers are turned off.
