# Default Range Description
Flow: Steam Flow Start Pressure Offset
The steam flow start pressure is an offset of the required pressure. Steam
flow metering will begin when the actual pressure is within this offset from
the required pressure, as the system would be generating useful steam.
0.1 – 10.0 bar or 1 – 100 PSI (see parameter 40)
Flow: Steam Flow Stop Pressure Offset
The steam flow stop pressure is an offset below the required pressure. if
the actual steam pressure below this value, then steam flow metering will
0.1 – 10.0 bar or 1 – 100 PSI (see parameter 40)
Flow: Heat Flow Data Source
For setting 0, the T1, T2 and T3 temperature sensor are wired to the MM,
and the heat flow function is set via expansion option 120.
For setting 1, the same temperature information is fed back to the MM via
connections to the IO module connected to the DTI. The ID number of the
IO module must be set in this option.
Sensors connected to IO Unit 1 – 10
Temp: Spare Temperature Sensor Function
Temp: Spare Temperature Shutdown Threshold
When this threshold is reached, the burner will shutdown and an alarm is
triggered and the burner shuts down. The temperature has to drop below
the threshold to allow the user to reset this alarm.
