editing purposes. Pressing the Up or Down button will increase or decrease the selected parameter number on the display. Although the parameter numbers are in numerical order, some numbers are skipped. These numbers represent reserved parameters that are not yet implemented and are not displayed. Once the desired parameter number is displayed, a press of the Enter button will change the display to the Value Mode.

Note: When in Parameter-Selection Mode, pressing the Enter button with parameter 0 selected will cause the unit to return to Running Mode.

Value Mode is used to modify the value of the selected parameter. When in Value Mode, the two dots which form the colon, between digits two and three, will alternately flash (one, then the other) to inform the user that a parameter’s value is being edited. Pressing the Up or Down button increases or decreases the selected parameter’s value. See the default value tables (below) for the list of preprogrammed values. Value changes take effect immediately. Once the desired value is showing in the display window, pressing the Enter button again will return to Parameter Selection Mode. The new value is not saved in permanent memory until the Enter button is pressed. Removing power from the unit while in Value Mode may result in the specified new value being lost.

Resetting the Unit to Un-Programmed State

The factory-default settings can be easily restored using either of two methods. Both methods require the Program Enable jumper to be in the “On” position. The first is to apply power to the unit with both the Enter and Down buttons pressed for 3 seconds. The second is to change the value of parameter 95 to 5.

JP1 (Program Enable Jumper)
