Can this be an ethernet type cable, or does it need the large rs232 cable connector?
We wish to only drill a small hole through the wall for running the cable.

Also, how long is the supplied...

Normally I just scan the ports and it will find the device. Once I manually input the Com port # it saw the device right away and connected. I unchecked the 485 delay and it works great.

Thanks to...

Hello,
I cannot connect to the new P3. I downloaded and installed both USB drivers. I have also tried my own USB to serial converter (which works fine on the P2). I get no fewer than 75 pop up...

Thanks Matthias. I love that you continually improve the system! Though I still wonder if I can perform this function in inverse.

From the 4.08 programming guide:
"Return pump
As soon as sensor...

It looks like there is NO provision for a "low sump condition" main pump cutout. If only I could invert the level sensor while set to leakage...

Has anyone been able to succeed with this...

I am trying to use prog logic to have the main circ pump shut down if either the tank level is high (water 1 set to leakage) or the sump gets too low (water 2). I have the logic down, but I cannot...

I had to have the profilux software search for the connected COM port. It found it, I switched to it, then it worked. I pulled my hair out until then.
Good luck:)

Exactly Michael:)
Several ways to switch the chiller depending on its size, voltage, etc. Ideally, you would just relay the Tstat wires on the chiller. But many chillers are wired differently, so...

Here is the contactor I used, along with the little cover box.

The easiest way would be to make a contactor box with the chiller 220v receptacle, and 220v plug coming out, with the 120v plug to plug into the powerbar.

I mounted the contactor right to the...

Thanks. I realize you only need one pH probe for the reactor. I guess my question should have been more clear. When using 2 probes; one for the reactor, one for the tank, what logic do you assign the...

Chippypah,
"2 X PH Probes, 1 for PH of tank the other for calk reactor"

may I ask how you programmed your 2 pH probes for this setup?
Thanks!

Sorry, I missed your question and just wrote this. http://www.aquariumcomputer.com/Forum/showthread.php?t=913

Very easy modification to the chiller. Let me know if you need help:)

How do I control a big 1HP 220V chiller from the GHL powerbar??? Simple!:)

I used a contactor for the chiller with a 120v coil. The chiller plugs direct to a 220v dedicated circuit, and the coil...

How do you all set up your Ca reactor CO2 with the Profilux? I know you all ditched them in favor of the cool dosers, but someone must still use a reactor?

Without having it open in front of me, I...

Please post it in the sketchup library for all to use! Awesome job!
