See section 3-7 for a range of choices and the default values.
TUNING MENU
MENU OPTIONS DESCRIPTION
1 Prop Band
Generates a fire rate based on the error that exists between
the setpoint temperature and the actual outlet temperature. If
the actual error is less than the proportional band setting (1°F
to 120°F, -17.2
°C to 48.9°C), the fire rate will be less than
100%. If the error is equal to or greater than the proportional
band setting, the fire rate will be 100%.
2 Integral Gain
This sets the fraction of the output, due to setpoint error, to
add or subtract from the output each minute to move towards
the setpoint. Gain is adjustable from 0.00 to 1.00 (Default is
1.0).
3 Derivative Time
This value (0.0 to 2.0 min.) responds to the rate of change of
the setpoint error. This is the time that this action advances
the output.
Warmup – The feature embodied in menu items 4, 5 and 6 eliminates Temperature
Overshoots during the “Warmup” period of a cold ignition cycle on all boilers by
temporarily modifying the PID Gain parameter during warmup and for a period defined in
the Tuning menu.
4 Warmup Prop Band
Range = 1 – 120°F (-17.2°C to 48.9°C) Default = 95 (35°C)
5 Warmup Int Gain Range = 0.00 – 2.00 Default = .50
6
Warmup PID Timer
Range = 0 - 240 seconds
Default = 20 seconds
7
Reset Defaults? Allows Tuning menu options to be reset to their Factory
Default values.
