I just got the powerbar STDL4-4 and currently have powerbar 5.1 to Profilux. Once I connect the STDL the switch channels on powerbar 5.1 change to 5-9 from 1-4? So do I have to reprogram these? I...

Eheim a mod exists to make it have an adapter it's easy. GHL I am hoping comes out with their own. I did the mod and it works well

Ok, I tried that when I connect to the KH director the blue light on power supply goes out. I am thinking a short somewhere in the KH director itself. I opened it up and can't see anything wrong....

It seems something is wrong with my KH Director. When I plug in the 24v splitter into KH Director my doser shuts off. I even tried using a 12V connection seems like it's a short. What is...

GHL Doser 2.1 with KH Director. I am about to finish installation.

I have the doser on switch channel 5. Do I keep this switch always on? I want to be able to only have doser + KH on when I do a test? Is this possible? Thanks

I did that and seems that heater is always on and temp never changes. I may disconnect from GHL and try it without control to see if it's heater. Are all heaters compatible though?

I have a Fluval E Heater and trying to control it through GHL. It seems not able to control the heater. I have GHL set at 78 degrees Fahrenheit and GHL temp probe reading 76.7; Heater reading 76.5.
