flow metering will begin when the actual pressure is within this offset from
the required pressure, as the system would be generating useful steam.

129 0 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 up to the MM via connections
to the IO module connected to the DTI. The ID number of the IO module
must be set in expansion option 129.
