EGA: Trim Threshold
The trim threshold is an offset from the required setpoint; if the actual
value is below this offset, then the EGA will not trim. This option should be
set to 0 if trim is to be effective at all times during firing, and/or if external
modulation is optioned. No single point changes can be made if the actual
value is below this trim threshold.

MM: Golden Start
Golden start allows an optimum ignition position to be set in the fuel-air
curve,
which is not necessarily low flame or part of the standard
modulating index. Parameter 15 sets how long golden start position is
maintained and from which point to start counting down.

DTI: Minimum Remote Setpoint (DTI/ Modbus/External)
If a required value command is received from the DTI or Modbus that is
below this minimum remote setpoint value, then it will be ignored by the
MM. The MM will continue to fire to meet the previous required setpoint.
