Start-Up
When the fan switch is in the off position, the controller does not control any unit capacity. The unit
remains powered and all outputs drive to the closed position. Upon a loss of signal on the fan speed
input, the controller reports a diagnostic and reverts to using the default fan speed.
On/Cancel Buttons
Momentarily pressing the on button during unoccupied mode places the controller in occupied
bypass mode for 120 minutes. You can adjust the number of minutes in the unit controller
configuration using Rover™ service tool. The controller remains in occupied bypass mode until the
override time expires or until you press the Cancel button.
Communication Jack
Use the RJ-11 communication as the connection point from Rover™ service tool to the
communication link—when the communication jack is wired to the communication link at the
controller. By accessing the communication jack via Rover, you gain access to any controller on the
link.
