RELAY (Production standard settings here under shown).
The key "+" operates as cursor; it moves through the numbers corresponding to the four programmable relays
in the sequence 1,2,3,4,(1= relay R1, etc.) and makes start flashing the information actually present in the
digit. The information present in the digit can be either the number of the relay (if this was already associated

The key "-" changes the existing status from the dot to the relay number or vice versa.
After having programmed all four relays, press “ ENTER “ to validate the programmed
configuration.
