Hi,

Would it be possible to have some kind of feature that would be the opposite of feeding pause, where it would be possible to have a socket be normally controlled via a sensor/probe, and then have the possibility of pushing a button (like with the feeding pause) to have it be always on for a set time (10min or 20min). Sounds impossible to me, but I thought maybe somebody have found a way around this?

Thanks

Scott

Look into the maintenance feature. You can set a socket on/off or 1-10V Interface at a value for a given amount of time.

Thanks for the reply. I thought the maintenance feature was for switching devices off only. That feature is quite handy. I'll try it out tomorrow.

Hi all
I want to run a Rosing pump as the feeder of water from sump into a nitrate reactor and have a probe measure the redox in the NR. Then what I would like to do is switch pump on when the redox is at level A let's say -150mV and when it gets to -100mV switch the pump off and let the NR work and once the reading is -150 switch dozing pump on again.... Thus keeping the NR happy and working at optimum levels.

Is -150 ~-100 the best range and any tips on how to program this on the p3 with a stand alone Rosing pump being switched via a pab 6 power bar?
