Eg. in the following manner:
Plug in first cable: L1L2 to tunze
Set function of 1-10V-interface1 to dimm channel 1
Set function of 1-10V-interface2 to dimm channel 2
(the voltages can remanin)
Go to menu "manual light intensity"
switch off auto - yes
Dimm up and down D1 and D2
Reacts the pump on D1 or D2? Then you know it is Tunze1 or Tunze2
(The other cable is then also clear)
Don't forget to set again the 1-10V interfaces you need to pump1/2
