Password Protection — If an area is entered that is 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 ENTER 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 ENTER 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 ENTER 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 ENTER 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 ENTER key to make the value flash. Next, use the arrow

keys to adjust the item to the desired value and press ENTER .
