Lochinvar 000 through 2, 1 warranty Password Function, Configuring Command Display

Page 40

The Command Display provides a communication interface with the Excel 10 via a series of display screens. The front view of the display screen shows the digital display with a cluster of arrow keys on the lower left side. These directional arrow keys move the cursor in the direction of the arrow.

On the lower right side is a back key which moves the display to the previous screen and a select key which highlights a field in the display.

There are also four softkeys along the right side of the display. A notation on the specific screen defines the function of each of these keys. The softkeys may be defined as configure, change, save, cancel, + to increase a value or - to decrease a value on the screen.

PASSWORD FUNCTION

On initial operation of the Intelli-Finthe owner may enter three levels of password with the Command Display to limit access to the changeable operating parameters in the Excel 10. Each password is composed of a four digit number. As shipped from the factory all passwords are zeros. The first level of password allows access to the six changeable points accessible from the Command Display. The second level of password allows access to the configuration settings of the Command Display. The third level of password allows the password to be changed.

FIG. 55 Command Display Password Screen

The configure button also allows the user to access the password function to enter a password in the Excel 10 from the Command Display. Use of a password will limit the access to the changeable points. When located at the password screen, move the cursor to the first blank space (by using the left or right buttons on the left side of the Command Display). Use the “+” or “-” buttons on the right side of the Command Display to either increase (+) or decrease (-) the number to the desired number. Then use the left or right buttons to move the cursor to the next space and repeat this procedure. Once the password has been entered, push the “SAVE” button. Once a password number sequence has been entered into the Command Display, they must be correctly reentered to change any of the six adjustable points. If an incorrect password sequence is entered, the password screen will stay in place.

NOTE:

Once a password is correctly entered, it will not have to be reentered unless five minutes of inactivity on the Command Display has elapsed.

CONFIGURING THE

COMMAND DISPLAY

When the “CONFIGURE” button on the right side of the Command Display is pressed, a password screen will appear. The user must enter the appropriate password and press “SAVE” to access the changeable screen. Pressing this button provides access to a “setup” screen that allows the user to adjust such items as:

ACCESSING THE SIX

CHANGEABLE POINTS FROM

THE COMMAND DISPLAY

When the “CHANGE” button on the right side of the control is pressed, a password screen will appear. The user must enter the appropriate password and press “SAVE” to access the changeable screen. The desired point to change must be highlighted by moving the cursor and then use the “+” or “-” buttons on the right side to change the value to the desired value. Once the desired value is reached, press the “SAVE” button and the new value will be saved and the Command Display will return to the first screen of the 21 points for that boiler/water heater. The password must be entered each time a user wants to change the settings of any of the six changeable points. However, if you go to the screen again within 5 minutes of the last time, it will not require the password again. If the screen is left in the changeable point screen for more than 5 minutes with no activity, it will automatically return to the first screen of the 21 points for the boiler/water heater. Re-entry into this changeable point screen will then require password access again.
