Not sure if the IC is for energy savings, but I do know if the IC goes out in the pump you have to replace the whole unit as it controls the pump and monitors cooling.
The DCT models have the IC in the controller which is only $19 to replace if it overheats and goes out. DCT models are more in line with the gen 2 Waveline Pumps and RODC pumps by Coralvue.
And for sure.. It'll be nice to chat about the new tech out there... especially if we get it at a great price compared to other brands... I currently have a dc12000... its a workhorse.... +1 for anyone who is looking into Jebao pumps.
