The large dial on the face of the network sensor functions in two ways: to increase or decrease the setpoint temperature, and to change the controller mode from unoccupied and occupied. When the dial is rotated slightly, the backlight on the LCD lights up. If the dial is rotated slightly again, and the controller is in the unoccupied mode, the controller changes from the after-normal-working-hours setback mode to the normal-working-hours comfort mode. To adjust the setpoint, continue rotating the dial until the current setpoint is displayed and flashing. Turn the dial clockwise to increase the setpoint and counterclockwise to decrease the setpoint. Stop turning the dial once the desired setpoint is reached. The new setpoint stops flashing and becomes fixed after a few seconds.
