Pressing the DOWN key will display the Cool PID screen shown on Figure 51.
This screen allows the PID loop for cooling mode to be modified. The PID
setting of the Gain (or Proportional Band), Reset (or Integral) and the Rate (or
Derivative) can be modified here. The range of the Gain is 0 to 32767. The
range of the Reset is 0 to 32767. The range of the Rate is 0 to 32767. The
supply air temperature is shown here as well as the set point used in this mode.
The Loop Cmd is also displayed here to aid in the tuning of the PID loop.
To modify these set points, press the ENTER key and use the arrow keys until
the desired setting is shown. Pressing the ENTER key will now change the
set point.
Pressing the DOWN key will display the Htpmp PID screen shown on Figure
52. This screen allows the PID loop for heating mode to be modified. The PID
setting of the Gain (or Proportional Band), Reset (or Integral) and the Rate (or
Derivative) can be modified here. The range of the Gain is 0 to 32767. The
range of the Reset is 0 to 32767. The range of the Rate is 0 to 32767. The
