I am still waiting for approval for the DA forums but I will ask here as well. I have a month old ReefKeeper lite basic that was configured to run my Return pump, skimmer, and heater. I wanted to use it for ATO and wanted a PH probe so I added an SLV2. Now I want to be able to view over the internet so I picked up a NET controller. I have individually updated all modules to the latest firmware. So here is the configuration

RKL Head Unit --> PC4 --> NET --> SLV2 --> temp probe

The return pump is configured has a standard pump that shuts off when in standby
The skimmer also shuts off in standby but stays off for 10 more minutes
The ATO pump is configured off a switch port on the SLV2 on when open off when closed.
The heater is set to come on or off based on the temp probe.

Here is my issue. Everything is connected and running. I can view everything online and make changes. If I hit standby everything shuts down that is supposed to. However, when standby expires the return pump kicks back on but the skimmer and the ATO will not power back up. The on light on the PC4 is blue saying the port is on. And if I connect the computer and manually move the float switch the PC4 and the software show open or closed but does not power the socket. If I unplug the bus cable from the NET module and plug it back in everything turns on except for the ATO it will not operate period if the NET module is in the loop. Additionally if I plug the SID at the end of the loop in place of the temp probe the software is very buggy and sluggish when the NET module is in the loop.

I have a theory but wanted to see if I am on track. The skimmer and the Aqualifter pump are on PC4 channel 1 and 4. I think those are both the mechanical relay channels. The aqualifter pump will only work for me on one of the mechanical relay channels. Most diagrams I see running similar setups have two PC4’s Is it possible I need another PC4 for more power to run multiple modules?
 
I replied to your post on another forum.
 
Instead of a PC4 you could just get the RK-HUB which allows you to power it with a 9v power supply. It does not count as a module toward the 4 module limit. Both the NET module as well as the SL2v2 use a lot of power from the bus. That could be the issue.
