Generates a valve position 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 to 120°F,
-17.2 to 48.9 °C), the valve position will be less than 100%. If the
error is equal to or greater than the proportional band setting, the
valve position will be 8%.
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 10.00
This value (0.0 to 20.0 min.) responds to the rate of change of the
setpoint error. This is the time that this action advances the
output.
The feature embodied in the next three menu items 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.
Range = 1 – 120°F (-17.9°C to 48.9°C)
Range = 0.00 – 2.00
Range = 0 - 240 seconds
Setting is adjustable from -50°F to +50°F. It adjusts the output by
adding an offset to the breakpoint chart at minimum flow. This is
used to fine tune Feed-Forward (FFWD) output at low flow levels.
Setting is adjustable from -50°F to +50°F (-45.5 to +10 °C). It
adjusts the output by changing the scaling of the breakpoint chart
at maximum flow.
Displays the Feed-Forward temperature.
Used to Enable or Disable feedback. Disable this function for
Feed-Forward control only.
Adjustable from 0.01 to 1.00 (See NOTE below)
Allows breakpoint temperature settings 30°F to 240°F (4.4°C to
115.6°C), to be entered for 100% to 0% in 10% increments.
