Hi to all,
i have an issue controlling my 4 tunze 6095 pumps.
Pump1 and Pump2 are connected to L1L2 via y cable and tunze 1 and 2 control cables
Pump3 and Pump4 are connected to L3L4 via y cable and tunze 1 and 2 control cables
Steam Group configuration as follows:
Steam Group 1:

Steam Group 2:

Pumps on steam group 2 are working fine
I am only having trouble with Pump1/L1 on Steam Group 1 that is not running. Different pumps were tested, different y cable and different control cables (control cables were also switched).
After many tests, I found something curious:
The only time Pump1/L1 is running is when Pump2/L2 is stopped. But when Pump2/L2 starts Pump1/L1 Stops. Configuration tested on Steam Group 1 with Pump2/L2 minimum speed to 0:

Tunze with 20v jumpers and set at 3 to 10 for the 1-10 voltage. Voltage always presented.
