"You can use timers yes and have the digital bar set to permanent on but does that not defeat the object of even using the profiLux for your lighting, you may as well in this case plug them straight into a wall socket on a timer."
Sure I get what you're saying. IMO it does not defeat the purpose entirely. Like I said, I am mostly wanting the profilux to be able to turn OFF the MH lights if temp rises too high, in case the chiller fails, or my house AC fails and the air temp goes off the charts (omg last summer my house got in the 90s while the AC broke!)
Im primarily using the profilux for the pH control, ATO and dosing.
would you say that an ATI Powermodule with 4x39W T5 lighting should be on high AMP load? This is the lighting for my frag tank.
btw im crazy about redundancy. for temp control I'm going to use a Ranco plugged into the powerbar, and then hook up 2x250W heaters to the ranco. this way heaters only go on if both profilux and ranco agree they should be on.
of course I suppose it also doubles the chance that NO heating will occur, but I think thats much less serious than heaters staying on. I' welcome feedback on that idea.
Thanks!
