PROGRAMMING

1. Select the feature to program by 

    rotating the “MODE SELECT” switch

    to the desired position.  The “MULT” 

    setting must be programmed before

    any of the current settings to ensure

    proper display of actual current 

    setpoints.  Therefore, SymCom 

    recommends programming the “LV” 

    setting first, then move clockwise 

    through the postions to complete the

    process.  

2. Push and hold the RESET / PROGRAM button.

3. Rotate the DISPLAY / PROGRAM adjustment  to the desired setting of the  

    feature as shown in the LED display.

4. Release the RESET / PROGRAM button.  The unit is programmed when the  

    button is released.

5. Continue steps 1-4 until all features are programmed.

NOTE:

  Some “MODE SELECT” positions are dual functioning such as the 

 

“#RU / ADDR” position.  When the “MODE SELECT” switch is pointed  

 

at “#RU / ADDR,” you may view and program “#RU” and “ADDR.”  To 

 

view the two settings rotate the “DISPLAY / PROGRAM” adjustment  

             across its entire range.  You will see the “#RU” setting when the 

 

“DISPLAY / PROGRAM” adjustment is between approximately 7 o’clock  

 

and 11 o’clock.  You will see the “ADDR” setting

  

when the “DISPLAY/PROGRAM”adjustment is between approximately 

 

11 O’Clock and 5 o’clock.  To program “#RU” or “ADDR,” follow the 

 

programming instructions above.  The “#RU” setting will only be 

 

programmed when the “DISPLAY / PROGRAM” adjustment is between 

             approximately 7 o’clock and 11 O’Clock.  Likewise, the “ADDR” setting  

 

will only be programmed when the “DISPLAY/PROGRAM”adjustment is 

 

between approximately 11 o’clock and 5 o’clock.  “ADDR” settings will  

 

be an “A” followed by a number between 1 and 99.
