MENU LEVEL & OPTION DESCRIPTION
TUNING MENU
Prop Band 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), 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%.
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 = 1.6).
Derivative Time 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.
Min Load Adj 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. (Default = zero)
Max Load Adj Setting is adjustable from -50°F to +50°F. It adjusts the
output by changing the scaling of the breakpoint chart at
maximum flow. (Default = zero).
FFWD Temp Displays the Feed-Forward temperature.
Outlet Feedback Used to Enable or Disable feedback. Disable this function
for Feed-Forward control only.
Feedback Gain* Adjustable from 0.01 to 1.00 (Default = 0.05).
Breakpoint at 100%
Thru
Breakpoint at 0% Allows breakpoint temperature settings (30°F to 240°F) to
be entered for 100% to 0% in 10% increments. See
Appendix D for default values.
Reset Defaults? Allows Tuning Menu options to be reset to their Factory
Default values.
WHM Min Addr Set the minimum address of the heaters to be controlled by
the master. The WHM Min Addr and WHM Max Addr must
differ by no more than 7. (Default = 1)
WHM Max Addr Set the maximum address of the heaters to be controlled
by the master. The WHM Min Addr and WHM Max Addr
must differ by no more than 7. (Default = 8)
SSD Address Set this address to 247 if the WHM system is being
monitored by a Protonode with Slave –Slave (SSD)
programming. Otherwise leave it at zero (0). (Default = 0)
* Only displayed when Heater Tuning Display is enabled by factory authorized personnel.
