VAV Units
If the RTRM loses input from the building management system, the RTRM will control in the default
mode after approximately 15 minutes. For VAV units, a "shorted" mode input is the only input
required for the "Default Mode" to operate. If the RTRM loses setpoint inputs from the RTAM due
to remote setpoint input failure, the RTRM will use default setpoint inputs as defined in the default
chart for VAV units.
