password protected or an item is selected for change that is
password protected, the Navigator™ module will display:
Enter Password
The first digit of the password will be flashing. Hold either
of the arrow keys down to change the value of the first digit (if
necessary) and press
to accept. Repeat the process for
the remaining three digits.
Password for 30RB units is 0111.
Password for all other units is 1111.
The message “Invalid Password” is displayed if the pass-
word is not correct. The password can be disabled from the
Navigator module, and can be changed.
Forcing Values and Configuring Items — Cer-
tain items are allowed to be forced and other items are
user-configurable. Both of these changes can be made using
the Navigator module. See the unit’s Control, Start-Up, Service
and Troubleshooting Guide for a list of forcible and config-
urable values.
To force an item, position the pointer at the item. Press the
key and if the point can be forced or configured, its
current value will flash. Use the arrow keys to adjust the tem-
perature to the desired value. Press the
key when
finished. The Navigator module will display a lowercase ‘f’ to
the right of the value if it has been forced. If no ‘f’ is displayed,
the item was configurable. To clear a force, press
so
that the value is again flashing. Simultaneously press the up
and down arrow keys. The value will stop flashing, the ‘f’ will
be removed, and the parameter will revert to its corresponding
input channel value.
To edit a user-configurable item, operate the unit in
Service Test mode, or reset current alarms or history, and use
the
key to make the value flash. Next, use the arrow
keys to adjust the item to the desired value and press .
