When the burner is ignited all displays of the regulator light up. The set point display will blink for about 10 seconds. The value
in the upper field of the display (red) indicates the actual value. The value in the lower field of the display (green) indicates the set
point currently programmed.
CHANGING THE SET POINT
To change the set point, proceed as follows: - -
- -
Change the value of set point SP1 using the t and s keys. e
- -
return to normal display press
* *
The value of SP1 depends on the value set previously in configuration level C111.
SETTING PID PARAMETERS
PID parameters are factory set to standard mean values. The operation of the regulator can be self-adapted to suit the system by
activating the "tunE" function. The regulator will set the PID parameters automatically. To activate the "tunE" function proceed
as follows: - -
- -
With the burner in operation, press
blinking, the self-adaptation routine has been completed. - -
* *
The "tunE" function cannot be activated in Manual mode, or when the burner is off.
The PID parameters can be corrected manually from the parameters level, working on the proportional band Pb1, the derivati-
ve action time dt and the integral action time rt.
To change parameters Pb1, dt and rt, proceeds as follows: - -

DIFFERENTIAL SETTING FOR IGNITION AND SHUTOFF
The regulator allows the selection of an adjustable switching differential that establishes burner ignition and shutoff values.
HYS1 indicates the lower ignition limit, below which the regulator switches the burner to maximum power. HYS3 indicates
the upper shutoff limit, above which the regulator switches the burner off. To set HYS1 and HYS3 proceed as follows: - -
