Network Interface Controller for Tempered Air Products

The Overrides menu is for start-up, commissioning and troubleshooting.
This menu allows the user to override the control loops. If further control is
required, the user can also manually control the controller inputs and outputs.
To access the Overrides sub-menu, enter the service password (Default=1000).

To manually override an output, in each respective screen, change the override
from No to Yes, then change the Position to open or closed or adjust the vdc
output setting.

To resume normal operation after overriding the controller, simply cycle power
to the unit.

This menu allows the user to manually control the outputs of the controller. The
user can manually control the analog outputs and digital outputs. EXTREME
CAUTION should be used when manually controlling the outputs and should
only be used as a troubleshooting feature. If the controller is powered down,
overrides are reset to off. Therefore, if using this troubleshooting feature, the
best way to clear manually input values is to power down the controller.
