Set a program with a run time of 23:50. It will be off for 10 min a day.
Never tried it but, you might be able to get it to run all day if you set a second program (layer) to run during the time that the first program has it turned off.
Follow instructions on your right hand door.
after you finish programming first layer by hitting the program button, hit it again, then hit the same aux you just programmed. Your new program should be displayed. Now hit the same aux one more time. Now display should read PROG2. Go ahead and now program the aux to run in the time that the first program has the pump shut off, (start time and run time) . And of course, when you are done, hit the program button to exit programming.
