Hi,

I have been playing around with programmable logic to get skimmer delay after the stream pump but still can not get it to work. The followings are my desired outcome:

1/ Skimmer is delayed 10 mins after a power cut: this can be set up by Blackout - Delay

2/ Both Skimmer and Stream pump is turned off during maintenance 1 for 20 mins. I have done this in the maintenance function. When the maintenance finished, i want to delay the skimmer 10 mins after the Stream pump is turned on to prevent skimmer overflow

3/ Both Skimmer and Stream Pump is turn off during feed mode. When Stream pump is on again, Skimmer is delayed by 10 minutes

4/ When manual override power socket, I want to set it whenever i turn off power socket 1 (stream pump), the power socket 2 is off (skimmer). When i turn on the socket 1, socket 2 will be delayed for 10 minutes

So in other words, I would love to see the skimmer is off when stream pump is off, and on after 10 minutes the pump is on.

Thanks so much for your help,

:p

please try this:
Power plug of the Skimmer ist set to P1
P1 = P2 and P4
P2 = not P3
P3 = Pulse Maintenance 1 30 minutes
P4 = not P5
P5 = Pulse P6 (time of feed mode + delay)
P6 = not Filter 1

Hi Gandalf,

Thanks for your help. I made a modification from your recommendation and it works just fine:

P1 = P2 and P4
P2 = not P3
P3 = Delay-on Maintenance 1 10 minutes
P4 = not P5
P5 = Delay-off P6 10 minutes
P6 = Not Filter 1

Although the programming works just fine now, i am a bit confused why "P5 = Delay off P6" is working. When i changed it to "P5= Delay on P6", the delay happen when the Filter is on. When filter is off, the socket return immediately :D
