Viewing Channels
Editable Parameters
If you have enabled the Gauge Display Editable Parameters on the
Preferences screen, you can edit the following fields by double-clicking
them, typing the change, and pressing the Enter key.
• Setpoint
• Control Mode
• Heat PID Output %
• Cool PID Output %
You can set the Heat PID Output % and Cool PID Output % only when
the channel is in manual control mode.
Digital I/O
Select Digital I/O to display the Digital I/O screen, shown in Figure 8-4.
This screen allows you to view the controller’s digital inputs and
outputs.
FIGURE 8-4 Digital I/O Screen
Inputs
Simulated LEDs show the status of the inputs. If an input is High
(green), it is at 5 volts. If the input is Low (red), it is at 0 Volts. Inputs
are read-only. You can test an input by shorting it to controller common
and watching the LED change on the screen. Inputs will read high when
not connected to anything and low when grounded to the controller
common.
Outputs
You can set outputs manually to high or low. Any output that has been
previously assigned as a control output will not be selectable. For
instance, in the example shown in Figure 8-4, outputs 1 through 9 are
used as control outputs for the channels and cannot be toggled on the
screen.
