OSC 2 powerheads not working for me as planned

[jnb]

The are 2 powerheads on each side of the tank NSL NSR
I thought my statments turn the NSL on for 255 minutes then it would turn off and the right one would kick in but I just found that they are both off.

The middle statment shuts off NSL when the lights go off at which point I would expect NSR to go on/off every 255 minutes -

I really want these 2 pumps to have opposite schedules - what did I do wrong?


OSC 255/255 ON/OFF Then NSL ON
If Timer LNL = OFF Then NSL OFF
OSC 255/255 ON/OFF Then NSR OFF

The NSL pump may be out of sync when the timer LNL becomes inactive. Instead use this code:

If Timer NSR = OFF Then NSL ON
If Timer NSR = ON Then NSL OFF
If Timer LNL = OFF Then NSL OFF
OSC 255/255 ON/OFF Then NSR OFF
