- press key A (red LED on)
- enter the new programming code with 1 to 8
digits (from 0 to 99999999)
- press key A (red LED flashes)
- enter 55
- press key A (red LED off).
Changing the activation codes of relay 1
To change the activation codes of relay 1:
- enter the programming code
- press key A (red LED flashes)
- enter 01 (identification code of relay 1)
- press key A (red LED on)
- enter a number with 1 to 8 digits to pro-
gramme code 1 (from 0 to 99999999)
- press key A
- enter a number with 1 to 8 digits to pro-
gramme code 2 (from 0 to 99999999)
- press key A
- enter a number with 1 to 8 digits to pro-
gramme code 3 (from 0 to 99999999)
- press key A
- repeat the operation to programme all codes
as necessary (max.12). When program-
ming is completed press key A repeatedly
until the red LED starts flashing
- enter 55

Changing the activation codes of relay 2
To change the activation codes of relay 2
follow the procedure described above, chang-
ing the relay identification code (02 instead of
01).
Changing one relay activation code
To change one relay activation code, without
modifying the others:
- enter the programming code
- press key A (red LED flashes)
- enter 01 or 02 (for relay 1 or 2, respectively)
- press key A (red LED on)
- press key A repeatedly to reach the code to
be changed
- enter a number with 1 to 8 digits (from 0 to
99999999)
- press key A repeatedly until the red LED
starts flashing
- enter 55
- press key A (red LED off).

To delete one relay activation code, without
modifying the others:
- enter the programming code
- press key A (red LED flashes)
- enter 90
- press key A (red LED on)
- enter a 3-digit number “nxx”; n indicates the
relay associated with the code to be deleted
(1 or 2); xx indicates the code to be deleted
(from 01 to 12)
