A passcode access security feature is provided with the 489. The passcode is defaulted to
"0" (without the quotes) at the time of shipping. Passcode protection is ignored when the
passcode is "0". In this case, the setpoint access jumper is the only protection when
programming setpoints from the front panel keypad and setpoints may be altered using

installed and the passcode must be entered, to program setpoints from the front panel
keypad. The passcode must also be entered individually from each serial communications
port to gain setpoint programming access from that port.
