JC, mind being a guinea pig? ;p i dont have any channels open, but i had tried it on a couple of equipment that were less important and i think i got it to work but just need someone else to verify this for sure. someone logged on and told me it would work, but dont know. These are the two versions i made, first one is for people that like to add and take out water at the same, second is for those worried about running 2 pumps at the same time:

"okay i think i got this, let me just run this past you guys

Lets just assume that both pumps will take out/add an equal amount of water, and lets say that were going to have to shutoff the ATO so it doesnt interfere...this is what im thinking:

Saltwater Change

Things we need to do:
PUMP A (takes out water)
PUMP B (puts in water)
Turn OFF ATO


Timer 01
Monday through Sunday
Start at 8:40am
RUN time = 5 minutes
OFF= 0

PUMP A:
Multi-timer = Timer 01

PUMP B
Multi-timer = Timer 01


Alarm 01 = Device: choose EITHER pump channel..
Value = .50
Trip = Above

Go to your ATO channel and turn on Alarm 01
if Alarm = OFF

Saltwater Change: version 2

Things we need to do:
PUMP A (takes out water)
PUMP B (puts in water)
Turn OFF ATO
Turn OFF Return Pump


Timer 01

Start at 8:40am
RUN time = 5 minutes
OFF= 0

Timer 02
Monday through Sunday

Multi-timer = Timer 01

PUMP B
