-continued- 

Press the “

3 Select”

 button to continue.  The “C” LED flashes and the display shows either “

F”

 for 

degrees Fahrenheit or “

C”

 for degrees Celsius.  Press the 

“1 Adjust-up

” arrow or 

“2 Adjust-down

” 

arrow to toggle the mode as desired. 
 
Press the 

“3 Select

” button to continue.  The code LED is on and the display shows “PIN”.  To set a 

new user PIN code, press the “

1 Adjust-up”

 button.  The display will flash “4”, prompting an entry of a 

four button sequence using the 

“1 Adjust-up”, “2 Adjust-down”, “3 Select” 

and/or

 “4 Exit” 

buttons.  (Any sequence of the four buttons may be programmed as the code.)  As the buttons are 
pressed, the display will show the number of buttons that were pressed. 

 

NOTE:  After pressing a button, there will only be 5 seconds to press the next button.  If the 

next button is not pressed within the allotted time, the system will default to no PIN 
code, indicated by “0” on the display.  Once the sequence is entered the display will 
no longer flash, and will show “4”.
 

 

To program the no PIN code mode, press 

“2 Adjust-down

” and the display will show “0”, indicating 

no PIN code.  With no PIN code, pressing any button will permit access to the program. 
 

*** CAUTION *** 

 

Always record the selection sequence (PIN code) and store in a secure place. 

 

 

Press the 

“3 Select

” button to continue.  The filter LED flashes and the display will show “

FIL”

indicating the filter alarm days selection.  Press the 

“3 Select”

 button and the display will show the 

number of days that the alarm is set in one-half day increments.  Note that the alarm is based on 
compressor run time.  (Example:  10.5 indicates the alarm will activate every ten and one-half days or 
or 252 hours of compressor run time). 

 

Press the 

“1 Adjust-up

” or the 

“2 Adjust-down

” arrow to vary the desired number of days.  

Programming 0 days will disable the alarm. 

 

NOTE:  The required number of days to set this alarm will be determined by the ambient air 

conditions.  If rain or wash down hoods are installed on the system, no filter is 
supplied and the filter alarm should be set to “0”.  This will disable the filter alarm

.

 

 

Press the 

“3 Select

” button to continue.  The alarm LED will flash and the display will show “

Por”,

 

indicating the Power status.  The cool, heat, alarm and filter LEDs will be flashing.  Press “

3

 

Select” 

and the display shows

 “ON”

 or “

OFF”

 indicating the current power supply status to line voltage motor 

circuits.   Press 

“1 Adjust-up

” or 

“2 Adjust-down

” arrow to toggle the mode desired. 

(Version 3.18 and
