4 Actuators
4.1
Addressing the actuators
The addressing assigns to each actuator its proper function. The addressing is factory set by the burner manufacturer.
If an actuator must be replaced, it is necessary to address it, otherwise the system will not work. The parameter that sets the actuator function is
protected by the Service level password. Remember to check that the jumper "Bus termination" of the last actuator on the CAN bus is set to "On", before
starting addressing.

Params & Display
Actuators
To address an actuator, choose the corresponding actuator and follow the instructions on display:
When the actuator green LED flashes, it means that one of the following function is set according to the number of blinks:
Blinks
1 blink
2 blinks
3 blinks
4 blinks
5 blinks
6 blinks
CAUTION: it is recommended not to adjust the actuators. Anyway, never press the actuator red button, otherwise the
fundamental parameters, necessary for the burner operation, will be cancelled. The burner will therefore continuously
lock out
In case P1 was pressed for a long time, it will be necessary to perform a new addressing of the actuator.
ATTENTION: when the actuator LV green LED is always lit, it means that the actuator has not been addressed yet or it has been
reset and needs to be addressed again.
