I also have a broken Delta 3000, which is no longer supported by
Rosco, no parts, nada. I didn't
plug network POE to it but someone else may have. However, I have it working in Caveman Mode, which means that since the heater is good and the pump is good you can remove the electronics entirely, apply
power to the heater, then run the pump directly from a
dimmer. The pump is 120vac so this works. Of course this is not going to be condoned by the manufacturer, or anyone else probably, but as long as you do nice internal wiring with inline fuses
etc., and don't overflow the heater by keeping the pump under about 65%, it works. More than 65% and it spews fluid out the front. And since the pump
dimmer can be controlled by the light board, you can still
cue it. The heater still has the thermal
switch on it so it would trip if the heater somehow went out of control.
I went through the
circuit board in detail before I did this, the DC side showed good 12vdc, on the AC side the pump and heater SCRs checked out,
etc. I was not going to attempt a
circuit board repair that was certain to cost excessive time and money and had little or no guarantee of success.
