ato and water replacement questions
Hey All,
I also posted this on Reefcentral....
here is what i would like to do....
i will have 2 sensors
sensor 1 is low level
sensor 2 is high level
pump 1 is ro top off
pump 2 is empty from sump
pump 3 is refill saltwater from storage tank
normally when sensor 1 senses low level pump 1 turns on to refill until sensor 2 trips...turning pump off...normal ato......
on a certain schedule (daily or weekly) i would like to switch to water replacement....
pump 2 turns on and drains sump until sensor 1 trips...at that time pump 2 turns off and pump 3 turns on to refill sump.... when this completes the normal ato mentioned above resumes...
Can i do this? how
thanks
Larry

Can these water change vairables be achieved?

then do this: use socket function "[inverse] Water change" for the power outlet where the return pumps is connected
Hi
The problem I have with the above set up is when automating larger water changes, the return pump can not be turned off at the start.
The reason for this is that if the return pump is turned off then the water that flows over and resides in the overflow boxes and pipes will drain down into the sump and raise the level of the float switches in the sump above the original auto top up levels. This would complicate the automation when trying to return the levels to the normal levels after refilling the salt water.
The other problem is that if I leave the return pump running throughout the saltwater change, once the tank level has drained to below the overflow boxes, the last stage in the sump will empty! leaving my return pump running dry until it is filled up again. This could cause damage to my return pump and so I would not want to do this either.
The solution I have come up with is listed below and I would like to know from a moderator before purchasing the profilux 3 that I am able to program this with the software as this would be one of the main reasons I purchase the system. I travel quite alot and want to be able to perform salt water changes remotely whilst I am away.
Please see attached diagram to understand more fully
Pump 1 saltwater drain
Pump 2 saltwater fill
Pump 3 auto top off
Pump 4 return pump
Level sensor 1 (auto top) + (second saltwater fill)
Level sensor 2 (leakage detection) + (return pump)
Level sensor 3 (second auto top off) + (Salt water fill level)
Function: saltwater change
Level sensor 1 (auto top) CHANGES TO (second saltwater fill)
Level sensor 2 (leakage detection) CHANGES TO (return pump)
Level sensor 3 (second auto top off) CHANGES TO (Salt water fill level)
Pump 1 saltwater drain ON
Level sensor 2 (return pump) REACHES LOW LEVEL
Pump 4 return pump OFF
5 mins after function start ie. (Pump 1 saltwater drain ON)
Pump 1 saltwater drain OFF
Pump 2 saltwater fill ON (*Timer starts)
Level Sensor 2 (return pump) REACHES HIGHER LEVEL/ OR RAISES LEVEL
Pump 4 return pump ON
Level sensor 3 (Salt water fill level) or Level sensor 1 (second saltwater fill) REACHES LEVEL
Pump 2 saltwater fill OFF
(If maximum time limit is reached from *Timer start then pump automatically switches off, alarm sounds and email notification that problem has occurred. I no problems occurred then sensors switch back as below)
Level sensor 1 (second saltwater fill) CHANGES TO (auto top)
Level sensor 2 (return pump) CHANGES TO (leakage detection)
Level sensor 3 (Salt water fill level) CHANGES TO (second auto top off)
Can this be achieved?
