AO5 Outdoor air damper
1 The Rover service tool uses the unit type to determine and download the proper default analog output configuration. For
example, if you configure the controller as a space temperature controller, Rover will not allow AO1 to be configured for a sup-
ply fan speed output. Analog output AO1 is only used when the controller is configured as a variable-air-volume controller.
2 The normally open/closed configuration item refers to the inactive state of the end device, such as a cooling valve. If the device
is a normally open valve, the configuration for analog output AO2 must be normally open.
3 A normally face damper is positioned full coil face, and a normally bypass damper is positioned full coil bypass when the ana-
log output is at 0 Vdc.
