Hi,
New to this forum and a bit desperate.
I have an old AC3 that I bought about 2 weeks before Neptune switched over to the Apex.
It has behaved well until recently.
I Have a DC4HD for switching heaters and pumps.
It seemed like a good idea at the time to switch heavy power users with a box designed for that.
What is the problem?
I can only turn on one device at a time.
As soon as a second device is powered on everything shuts off and I must disconnect the DC4HD and then plug it back in.
If I only have one device turned on it seems to accept the commands given to it in AUTO.
All the other devices must be in Manual off.
As this is for my pumps and heaters you can imagine what a pita it is.

I doubt if I'll find a DC4HD anywhere for sale but I hope there are some used power bar 8's out there.
My system is the one that uses telephone connectors between the power bars.
Any and all suggestions are welcome.

Thanks.
