How to turn Off UV lamp when UV pump goes off.

[mlandscape]

New to GHL and can't get my mind around this programming yet and I am sure what I want is so simple.

I have my UV pump on Switch Channel 2 and the UV lamp on Switch Channel 3 and if the pump should ever go off I would like the UV lamp to switch off.

I currently have set both Switch Channels to Always On.

Anyone help me to sort this, please.

Many thanks

How would the ProfiLux know your UV pump went OFF?
Under what circumstances would this pump turn OFF? Feed pause, maintenance mode?

The reason I want to do this is to avoid the lamp being on without water flowing through the UV unit.
I am not sure how the Profilux would know how my UV pump is off that is why I am asking the question. It is not related to feeding pause or maintenance but just if the pump failed or the power to it went off.
I have this set up at the moment on the controller that is being replaced and it also switches the lamp off if the aquarium temperature gets above 27.2.

Hope that clarifies what I am needing. I could post the other controller code if that helps to explain it.

Many thanks

Yes, if you can post it that will clarify exactly how the task should be handled.
