Tunze 7095 Controller issue

Inversus · Feb 16, 2022

Hey there,

so Im currently in the process of filling my tank and I have enough water inside to play a bit with the two powerheads (tunze 6055) and the controller (7095).
But no matter what I do, the one powerhead wont work with the controller.

While the one is doing what I programmed (pulse), the other just works constantly on the same powerlevel set on the powerhead-controller.
I switched cables and channels, but nothing seems to work on it.

Any idea what Im doing wrong? (Unfortunately on one powerhead-controller the "wheel" broke, but I can set it with a screwdriver.)

It could be just that a calibration is needed to operate the newer pumps on the older model controllers, the signal voltage changed when we added the 7090. Older controllers like the 7095 and 7096 are made for the older signal voltage, typically if this is the cause, the pumps will not run on a speed below 50-60%. This video shows what to do.

Regarding your settings, on the 7095 both pumps are plugged into Channel 1, for an interval you need one pump in channel 1, one in channel 2. On the 7090's, set main power to 100% and pulse and pulse power to off when using external mode.

That was it... Thanks!
