Tuning Control Menu
(Steady State and Prog Modes)
Pressing TUNE in the area modification screen will access the tuning control menu. Inside this menu the
user can step through a list of values that can be modified using the PREV (F1) and NEXT (F2) keys. The
top line of the display will indicate the current operating mode. The second line of the display is the
current value that can be accessed. The third line of the display is the current setting for the displayed
value. Enter the new data using the numerical keypad. As in all SmartPad™ data entry, you must fill the
entire field before the information will be accepted.
Press ESC (F4) to exit the tuning control menu and return to the process variable screen.
Label Displayed Acceptable Data Range Description
AIR HEATER CONTROL
Control Band 00.00 to 99.99 Defines the proportion (P) portion of
the air temperature control loop.
AIR HEATER CONTROL
Rate 00.00 to 99.99 Defines the rate or integral (I) portion
of the air temperature control loop.
AIR HEATER CONTROL
Derivative 000 to 999 Defines the derivative (D) portion of
the air temperature control loop.
AIR HEATER CONTROL
Manual Adjust 00.00 to 99.99 Defines the air heater output balance
point. In Slow Damper mode the
damper control loop will integrate in
an attempt to control the air
temperature with an output
percentage that is equal to the
manual adjust setting.
AUX HEATER CONTROL
Set Point 00.00 to 99.99 Allows access to the auxiliary heater
control loop set point. * This set point
can be configured to be slaved to the
air set point.
AUX HEATER CONTROL
Actual 00.00 to 99.99 Displays the measured temperature
from the auxiliary RTD.
AUX HEATER CONTROL
Output 00.00 to 99.99 Displays the percentage output
(heater duty cycle) for the auxiliary
control loop
AUX HEATER CONTROL
Control Band 00.00 to 99.99 Defines the proportion (P) portion of
the auxiliary temperature control loop.
AUX HEATER CONTROL
Rate 00.00 to 99.99 Defines the rate or integral (I) portion
of the auxiliary temperature control
loop.
AUX HEATER CONTROL
Derivative 000 to 999 Defines the derivative (D) portion of
the auxiliary temperature control loop.
H2O HEATER CONTROL
Control Band 00.00 to 99.99 Defines the proportion (P) portion of
the water temperature control loop.
H2O HEATER CONTROL
Rate 00.00 to 99.99 Defines the rate or integral (I) portion
of the water temperature control loop.
H2O HEATER CONTROL
Derivative 000 to 999 Defines the derivative (D) portion of
the water temperature control loop.
RH CASCADE CONTROL
Control Band 00.00 to 99.99 Defines the proportion (P) portion of
the Rh cascade control loop.
RH CASCADE CONTROL
Rate 0.000 TO 9.999 Defines the rate or integral (I) portion
of the Rh cascade control loop. This
value will determine the rate of
change for the water set point.
RH CASCADE CONTROL
H2O Hi Limit 00.00 to 99.99 (varies with
hardware) Defines the maximum water
temperature set point that the system
will allow. This value is hardware
specific.
