Pump oscillation help please

I acquired a second DC8. I want the PH's on the right side to alternate opposite the PH's on the left side.

Right PH's on the right on for 15 minutes (Left PH's off).
Then the left side for 15 minutes (Right PH's off).


If I program my AC3 with the info below all pumps are on/off for 15 minutes, then they all go off and stay off:

OSC 015/015 ON/OFF Then PM1 ON
OSC 015/015 ON/OFF Then PM2 ON
OSC 015/015 ON/OFF Then PM3 ON
OSC 015/015 ON/OFF Then PM4 ON

If I program my AC3 with this data my left side only comes on and stays on.

OSC 015/015 ON/OFF Then PM1 ON
If Timer PM1 = On Then PM3 OFF
If Timer PM1= Off Then PM3 On
OSC 015/015 ON/OFF Then PM2 ON
If Timer PM2 = On Then PM4 OFF
If Timer PM2 = Off Then PM4 On
OSC 015/015 ON/OFF Then PM3 ON
If Timer PM3 = On Then PM1 OFF
If Timer PM3 = Off Then PM1 On
OSC 015/015 ON/OFF Then PM4 ON
If Timer PM4 = On Then PM2 OFF
If Timer PM4 = Off Then PM2 On

To say the least I'm a little confused
