Help with ATO

[ClawHammer]

Hi,
I have a Maxi Doser set up as an ATO using 1 x optical sensor. Is there away to restrict this from running at specific times so it’s not dispensing RODI at the same time the ION D or KH D are taking water samples?
Thanks,
Mark

You can add a timer so it is only active at a certain time.

Hi, thanks for reply.
Okay, so I’m not sure if this is right but I think it is.

Edit: Deleting this post so nobody else tries it as the entire contents, 24 litres, of my ATO container was dumped into the sump!

Turn off the always on switch and adding a timer would not add all your ATO.

Okay, you’re talking about using the PowerBar and I want to avoid that so I can use for controlling non GHL equipment.
I was really hoping there was a way for the Profilux to control this and stop the ATO running when the KH or ION D’s are taking sample water.

No I was talking about adding a timer to the control circuit that is being used for your ATO
