(6) If an alternate formula is to be used, move the black slide switch to the position of the formula to be used, and 

repeat steps #3 and #4. 

(7) When finished programming the pumps, move the slide switch back to the formula #1 position. 

DELAY TIMES 

(1) Select the desired formula using the black slide switch located on the front left corner of the circuit board, by 

moving the slide switch to either the formula #1 or #2 position. 

(2) Depress and release the “MODE SELECT” button until “DELAY TIME” L.E.D. is lit. 

(3) Depress and release “PROGRAM/PRIME” switch of the pump # to be programmed. The “DELAY TIME” L.E.D. 

will flash, indicating that a delay time is being programmed. 

(4) When sufficient delay time has been reached, press the “PROGRAM/PRIME” switch again. The flashing L.E.D. 

will shut off and the programmed time will be stored in memory. 

(5) Repeat steps #3 and #4 for each pump which requires a delay time. 

(6) If an alternate formula is to be used, move the black slide switch to the position of the formula to be used, and 

repeat steps #3 and #4. 

(7) When finished programming the pumps, move the slide switch back to the formula #1 position. 

SEQUENCE MODE OPERATION 

In sequence mode operation, a single continuous signal is used to activate a programmed “sequence” of run and 
delay times, or events. The signal MUST be present for the duration of programmed events. If the signal is 
interrupted, the “sequence” will stop and hold its position. If the signal is re-applied less than 3 minutes after 
interruption, the sequence of programmed events will continue from the interruption point. If the signal is re-applied 
more than 3 minutes after the interruption, the sequence will re-start from the first programmed event. The delay time 
is the amount of time that elapses from acknowledgment of the continuous signal to the time that the product is 
required for each and every pump. To select sequence mode, move the jumper located above the RELAY, SINGL, 
and SEQ. L.E.D.’s to the jumper terminals located above the SEQ. MODE L.E.D. (JP5). 

NOTE: Programming in SEQUENCE MODE can be done 

with the Black Slide Switch in the FORMULA #1 Position 

ONLY. 

PROGRAMMING RUN TIMES 

Programming run times can be performed by either of the two methods explained in detail in SIGNAL MODE 
OPERATION / PROGRAMMING RUN TIMES section of these instructions. When programming is complete, remove 
continuous signal. 

PROGRAMMING DELAY TIMES 

[METHOD 1: USING A WASH SIGNAL TO PROGRAM THE SEQUENCE] 

(1) Depress and release the “MODE SELECT” button until “DELAY TIME” L.E.D. is lit. 

(2) Apply an AC signal to the PUMP #1 input ONLY. NO other inputs can be used in SEQUENCE MODE. This 

signal usually represents the beginning of a wash cycle sequence. 

(3) While the signal is active, the DELAY TIME light will flash, representing the “running” of a wash cycle. After the 

desired delay time period, depress and release the PRIME/PROGRAM switch of the pump # to be activated at 
that interval in the washing machine cycle. The delay time for that pump # is now programmed. 
 
NOTE: The delay time can be programmed in any fraction of minutes, but ONLY MINUTES will be displayed on 
the three digit KDC timer display (ex: a programmed time of 0:00 to 0:59 will display “000"; a programmed time 
of 1:32 will display ”001"; a programmed time of 2:58 will display “002", etc). 

(4) The next pump to be programmed, can now be programmed using step #3. Pumps to be programmed can be 

selected in any sequence. Pumps do not have to be programmed in order (i.e. 2, 3, and 4). A pump CANNOT 
BE programmed to run more than one time during a “sequence”. 

(5) When programming is complete, remove continuous signal.
