GHL Programmable logic

I've been scratching my head and just can't figure out how to implement the following logic on my Profilux 4

I have 2 maintenance routines:

1) Water change: I turn most of the switches off, including skimmer and ATO pump
2) Filter floss change: Turn skimmer and ATO pump off only

When maintenance one is done, I want to wait 15 mins before the skimmer switch is turned on, and 20 minutes before the ATO pump is switched on.

When maintenance two is done, I want to wait 30 minutes before the skimmer switch is turned on, and 35 minutes before the ATO pump is switched on.

I know that the "Delayed off" function can be used for this purpose, but I just can't figure out how to properly use it.

I was thinking on doing something like this

Programable logic 1
Maintenance 1 DELAYED OFF 900s

Programable Logic 2
Maintenance 1 DELAYED OFF 1200s

Programable Logic 3
Maintenance 2 DELAYED OFF 1800s

Programable Logic 4
Maintenance 2 DELAYED OFF 2100s

Programable Logic 5
Programable Logic 1 NOR Programable Logic 3

Programable Logic 6
Programable Logic 2 NOR Programable Logic 4

This is not working. I don't think I can apply the DELAYED OFF function to the same maintenance with different delays, can I? How can I program this?

Thank you in advance for the help!

One Idea

Test


Programable logic 1
Maintenance 1 (invert) DELAYED ON 900s

Programable Logic 2
Maintenance 1 (invert) DELAYED ON 1200s

Programable Logic 3
Maintenance 2 (invert) DELAYED ON 1800s

Programable Logic 4
Maintenance 2 (invert) DELAYED ON 2100s

Programable Logic 5
Programable Logic 1 OR Programable Logic 3

Programable Logic 6
Programable Logic 2 OR Programable Logic 4

This is how I have mine set up

Thanks @Lasse I'll try this out and let you know if this works!

Thanks @Lasse I'll try this out and let you know if this works!

Unfortunately that didn't work I'll keep trying and let you if I find a way to make this to work

I think you may just need to make the following changes from your original post:

Programable logic 1
Maintenance 1 DELAYED OFF 900s

Programable Logic 2
Maintenance 1 DELAYED OFF 1200s

Programable Logic 3
Maintenance 2 DELAYED OFF 1800s

Programable Logic 4
Maintenance 2 DELAYED OFF 2100s

Programable Logic 5
Programable Logic 1 [Inverted] AND Programable Logic 3 [Inverted]

Programable Logic 6
Programable Logic 2 [Inverted] AND Programable Logic 4 [Inverted]

Here's how I have mine setup, if it helps.

You will need to use programable logic. Here's how I have mine setup using all four Feed Modes and Two Maintenance Modes to give you an idea how to do it.

Time Delay

Time delay for after each Maintenance Mode is set by G1 and G2.

Time delay for after each Feed Mode is set by G3, G4, G5 and G6.

Actuation of Time delay after either Maintenance Mode is set by G7.

Actuation of Time delay after any of the Feeds Modes is set by G10 (combining through G8 and G9).

Actuation of Time delay after any Maintenance or Feed Mode is set at G11. The G11 logic gate is applied to my skimmer and ATO to delay them 5 minutes after Maintenance or Feed Mode.

Feed Mode

The four Feed Modes are combined using G12, G13 and G14. The G14 logic gate is applied to my powerheads which I turn off during Feed Mode.

I was able to test today and this works. I had to use NOR. My time settings is for demonstrating - you have to put in your owns
