5.2 Integral Control
The Integral term is specified in option 7, where the “Integral time”, also known as “Reset time”, is set.
Within a threshold of the P-Band, the integral term has the effect of increasing or decreasing the burner firing
rate by a specific amount every “n” seconds. The amount the firing rate is adjusted by is specified in
parameter 106, the default is 10% of the difference between the measured and setpoint temperature or
pressure values, and the time period this amount is added, every “n” seconds, “n” is specified in option 7, the
default is 60s.
