Range Description
Time modulation rate is held at present value (Low Fire Spd or Fan Purge Spd
10 to 1200 (s) depending on the state and configuration of spare input) after the Fuel Valve
Energized Input (CS) is energized.
Time modulation rate is held at Fan Purge Spd after the Fuel Valve Energize Input
0 to 600 (s)
(CS) is de-energized.
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
0 to 10000
modulation rate tuning adjustment and provides the immediate modulation rate
response.
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
0 to 10000
modulation rate tuning adjustment that ramps the output over time (typically
minutes).
The Derivative gain value for boiler outlet temperature sensor control Modes. A
larger Derivative gain value produces a larger PID output contribution proportional to
0 to 10000
the rate of change of the error (Setpoint – Boiler Outlet Temperature). When set
equal to zero it has no effect on the output.
Proportional Gain value for Remote System Temperature sensor control Modes.
0 to 10000
Refer to Local PID P for explanation.
Integral Gain Term for Remote System Temperature sensor control Modes. Refer to
0 to 10000
Local PID I for explanation.
Derivative Gain Term for Remote System Temperature sensor control Modes. Refer
0 to 10000
to Local PID D for explanation.
Proportional Gain value for boiler Inlet temperature sensor control mode. A larger
gain value results in tighter, more active, PID control. Gain is the primary PID
0 to 10000 modulation rate tuning adjustment and provides the immediate mixing valve
modulation response.
Only visible when mixing valve = yes.
Integral gain value for boiler inlet temperature sensor control mode. A smaller value
makes the Integral ramp in less time (i.e., faster). Integral is a secondary PID
0 to 10000 modulation rate tuning adjustment that ramps the output over time (typically
minutes).
Only visible when mixing valve = yes.
The Derivative gain value for boiler inlet temperature sensor control mode. A larger
Derivative gain value produces a larger PID output contribution proportional to the
0 to 10000 rate of change of the error (Setpoint – Boiler Inlet Temperature). When set equal to
zero it has no effect on the output.
Only visible when mixing valve = yes.
Proportional Gain value for boiler differential (boiler outlet minus inlet temperature
0 to 10000 sensor) temperature control mode. Refer to Local PID P for explanation.
Only visible when mixing valve = yes.
Integral Gain value for boiler differential (boiler outlet minus inlet temperature
0 to 10000 sensor) temperature control mode. Refer to Local PID I for explanation.
Only visible when mixing valve = yes.
Derivative Gain Term for boiler differential (boiler outlet minus inlet temperature
0 to 10000 sensor) temperature control mode. Refer to Local PID D for explanation.
Only visible when mixing valve = yes.
