Typical TSBC PID Gain and Integral Settings
No. Range / Choices Parameter and Description
55 0 to 10000
Local PID P
Proportional Gain value for boiler outlet temperature sensor control Modes.
A larger gain value results in tighter, more active, PID control. Gain is the
primary PID modulation rate tuning adjustment and provides the immediate
modulation rate response.
Pick a gain based on the desired initial response. The burner modulation
rate can oscillate if the Proportional Gain is too large.
56 0 to 10000
Local PID I
Integral gain value for boiler outlet temperature sensor control Modes. A
smaller value makes the Integral ramp in less time (i.e., faster). Integral is a
secondary PID modulation rate tuning adjustment that ramps the output
over time (typically minutes) .
Based on the selected Local PID P, select the corresponding (from above
table) Integral value. Repeats per minute between 0.5 and 2.0 are typical.
The burner modulation rate can oscillate if the Integral time is too small.
57 0 to 10000
Local PID D
The Derivative gain value for boiler outlet temperature sensor control
Modes. A larger Derivative gain value produces a larger PID output
contribution proportional to the rate of change of the error (Setpoint – Boiler
Outlet Temperature). When set equal to zero it has no effect on the output.
58 0 to 10000
Remote PID P
Proportional Gain value for Remote System Temperature sensor control
Modes. Refer to Local PID P for explanation.
59 0 to 10000
Remote PID I
Integral Gain value for Remote System Temperature sensor control Modes.
Refer to Local PID I for explanation.
60 0 to 10000
Remote PID D
Derivative Gain value for Remote System Temperature sensor control
Modes. Refer to Local PID D for explanation.
