Tunze 0-10v?

[tmcca]

I just added my Tunze 6055 Pump to 0-10v input and setup as LPS Reef for pattern. For voltage i set it as 0-6.5v as I heard this is what its supposed to be. However, my pump isn't going on. Max speed I have is at 50. According to Hyros my Tunze is running 0.6GPH but it's not running.

Figured it out seems 20% lowest speed you can go

Yes, when using 0-10V, there is always a bottom speed you cannot go below. That speed depends on the pump itself. Some pumps can go as low as 10%, and others as high as 30%.

You mean that you connected the Tunze pump to the 0-10v OUTPUT, not the INPUT, correct? I was told you can not connect to the INPUT which is why I can not use a Wave Engine LE as it only has an INPUT.

Correct. If you want to control the pump's speed, the signal's direction needs to go from the HYDROS to the pump and not the other way around. Therefore, you need to use the 0-10V OUT port.
