“
programming card

KEY
) and a “
control unit

), which activates
the hydraulic valve through a solenoid.
The KEY is made up of a display and four buttons, it communicates with the BASE by radio signal at
short distances. A non-rechargeable battery feeds the two parts. The battery is sized to last ten years,
considering an ordinary use of the system. Timer information is available through the KEY. When the
KEY connects to the BASE wirelessly, it shows the state the BASE is in, it allows setting a new program,
