GHL Dosing Unit - 4 pumps

[Sirhc]

I installed a GHL dosing unit and it is programmed to socket S9-S12 connected to a digital powerbar. I have a Profilux Plus II.

I programmed pump no 1 to dose Kalkwasser say every hour, but how can I program it to do it only in the evening during lights off?

Or even better, can I program Pump 1 to dose kalkwasser (slowly) only when the Ph reached a certain level to raise it?


Thanks

Chris
