*The display text changes depending on the remote switch configuration (Configuration→UNIT→RM.CF). If RM.CF is set to 0 (No Remote Switch), then the display text will be “On” or “Off.” If RM.CF is set to 1 (Occupied/Unoccupied Switch), then the display text will be “Occupied” or “Unoccupied.” If RM.CF is set to 2 (Start/Stop), then the display text will be “Stop” or “Start.” If RM.CF is set to 3 (Override Switch), then the display text will be “No Override” or “Override.”
