Switch channel logic based on other switch channel

[BeanAnimal]

Quite simply -

My skimmer pump is on a switch channel.
The UV is plumbed inline with the skimmer.

I want the UV to shut off when/if the skimmer feed pump is shut off.

It would appear that there is a missing logic option "Switch Channel" as logic input.
I don't want to purchase a flow sensor for this (I don't want to clean the darn thing).

Thoughts?

How du you shout off the skimmer?

I don't currently. I know that I could setup a maintenance or similar logic to shut both off...

I was looking for more of a hard tie logic:

IF SWITCH 2 OFF (for any reason) THEN SWITCH 12 OFF
PERIOD

That way feed mode, maintenance, manual override, etc. would ALL ensure that the UV is not running.

I could also connect both to the single switch channel, but then I lose individual control and I eventually think I want the UV on a timer instead of 24/7

Also reading, I guess a flow sensor would not work either as they can't be incorporated into logic.

Did you find a resolution to this issue? I'm looking to do something similar between equipment and was surprised when I could not connect a switch as a "slave" to another

Just put the same function

What i understand - you can use a flow meter. You can set an alarm threshold for the flow meter and function for the UV-C outlet should be general alarm inverted. The UV-C will shout down at all alarms though You need also to use the filter function for the skimmer outlet if you want it to shout down in feed mode

Use a program logic using what ever logic is controlling your pump and your uv timer

I did not really look into it any further.

I don't think that would have worked for what I was trying to do.

OK
