RWF 40
- Setting parameters
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 cur-
rently 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.te s. -
turn 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 acti-
vating 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
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 deriva-
tive 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: -

MANUAL/AUTOMATIC MODE
To access "MANUAL" mode, press and hold
operation. It is deactivated automatically when the burner shuts off. When the LED above the hand symbol is alight, the regulator is in
manual mode and the position of the servocontrol can be changed using the t and s keys. The LEDS on the front of the regulator in-
dicate whether the servocontrol OPEN or CLOSE command is currently active. Pressing the t key the servocontrol OPENS. Pressing
the s key the servocontrol CLOSES. To select automatic mode press and hold
