MM: Modulating Motor Travel Speed Limit
If the speed of the motor is too fast, then decrease the value, and vice
versa. At other times other than modulation, the motors move at full speed
or at the value set in option 75. Movement is limited by the slowest
channel i.e the slowest moving motor.

MM: Purge Position
This purge position applies to channels 1-4 as selected in options 67-70,
however VSD channels will always purge at open position as default. This
setting applies for post-purge if set, see option/ parameter 118 and 135.
0
Channels 1 to 4 purge at HIGH position.

PID: Proportional Band
The proportional band is an offset below the required setpoint; when the
actual temperature/ pressure reaches this band, the burner will begin to
modulate as it approaches the required setpoint.

PID: Integral Time
Every ‘n’ seconds, 10% of the present offset from the required setpoint is
added or subtracted when below or above the setpoint, respectively, to the
present proportional value. The value of ‘n’ is the number of seconds set in
this option; if set to 0, there will be no integral control.
