Screw the short end of the long double bent pipe (C) between the electro valve and the
elbow piece (3).

Connect the valve to the controller of the module (see page 7 ff.) and activate
the automatic operation mode (see the separate instructions of the zone valve).

Convert the other Friwa modules in the same way.
7.
Connect the controllers of the cascade with the communication cable included
(see page 7 ff.).
