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 currently programmed.
CHANGING THE SET POINT
To change the set point, proceed as follows:
--
--
Press the
PGM
PGM
button to access the user level. SP1* will appear in the lower display
--
--
Change the value of set point SP1 using the t and s keys.

After a 2 second delay the value set is stored automatically – To
return to normal display press
EXIT
EXIT
.
**
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
PGM
PGM
+
▼
.
--
--
the caption “tunE*” will blink in the display. – When “tunE” stops
blinking, the self-adaptation routine has been completed.
--
--
Confirm the computed parameters by pressing the
▲
key for 2 seconds.
**
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
derivative action time dt and the integral action time rt.
To change parameters Pb1, dt and rt, proceeds as follows:
--
--
Press the
PGM
PGM
button to access the parameters level.
--
--
To move from
one parameter to the next, press
PGM
PGM
.
--
--
When
Pb1
is displayed, the value can be increased or decreased using the s and t keys.
--
--
Confirm the changed parameters by pressing
PGM

If confirmation is not given within 2 seconds the value will be stored
automatically.
--
--
Press

When dt is displayed, repeat the procedure described above.
--
--
Press
PGM to access the next parameter.
--
--
When rt is displayed, repeat the procedure above.

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: --
--
Press
the
PGM
PGM
key to access the parameters level.
--
--
To move from one parameter to the next, press
PGM
PGM
.
--
--
When
HYS1
is displayed
(burner ignition differential-stage II), increase or decrease the value using the
▼
and
▲
keys.
--

Confirm the changed parameters by
pressing

When
HYS2
is displayed (burner shutoff differential-stage II), repeat the procedure described above.
--
--
Press
PGM
PGM
to access the next parameter.

MANUAL/AUTOMATIC MODE
To access “MANUAL” mode, press and hold
EXIT
EXIT
for at least 5 seconds. Manual mode can only be selected when the burner is
in 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
▼
and
▲
keys. The LEDS on the front
of the regulator indicate whether the servocontrol OPEN or CLOSE command is currently active. Pressing the
▼
key the
servocontrol OPENS. Pressing the
▲
key the servocontrol CLOSES. To select automatic mode press and hold
EXIT
EXIT
for at least 5
seconds. The LED above the hand symbol goes out and the regulator reverts to automatic.
CLIMATIC COMPENSATION
The RWF 40 regulator can be set with the set point interlocked to the external probe. To select this operating mode, proceed as
follows:
--
--
Connect the required probe as in the wiring diagram.
--
--
Change the regulator settings. When using an external probe
the regulator must be set as follows:
--
--
Press the
PGM
PGM
key to access the configuration level. When the caption
C111
(XXXX) is
displayed, use the
▲
key to access the second figure (XXXX). Use the
▼
key to select the type of probe (XX3X).
--
--
Confirm the
change of parameters by pressing
PGM
PGM
