PL4 and Tunze 6020 & 6030 pumps

[jump]

Hello,

To add 2 Tunze 6020 or 6040 pumps to my future PL4 I need:
- 1 cable GHL Tunze1 (L1/L3) ?
- 2 Tunze controller (one for each pump) ?

Happy new year ;-)

Hi there,

Tunze 1 cable is controlled by "Odd" numbered L channels such as L1/L3/L5, etc.

Tunze 2 cable is controlled by "Even" numbered L channels such as L2/L4/L6, etc.

These cables are connected to the back of the P4's L ports. The other end of these cables are then connected into Tunze's 1-10v interface ports.
