- Microprocessor regulator - Setting parameters PArA
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, rt, proceeds as follows: - Press the
button, appare nel display di base
can be increased or decreased using the keys tand s (see table), press
parameter. - When dt is displayed, repeat the procedure described above. - Press
rt is displayed, repeat the procedure described above. - To return to normal display press
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 Enter button to access the parameters level

MANUAL/AUTOMATIC MODE
To access "MANUAL" mode, press and hold
ration. It is deactivated automatically when the burner shuts off. When the
the position of the servocontrol can be changed using the t and s keys. The LEDS on the front of the regulator indicate whether the
servocontrol OPEN or CLOSE command is currently active. Pressing the s key the servocontrol OPENS. Pressing the t key the ser-
vocontrol CLOSES. To select automatic mode press and hold
and the regulator reverts to automatic.
RESPONSE THRESHOLD (q)
The response threshold (q) defines for what period of time and how much the actual value is allowed to drop before the system swit-
ches to high-fire operation.
An internal mathematical calculation using an integration function determines the sum of all areas qeff = q1 + q2 + q3 as shown in the
graph. This takes place only when the control deviation (x-w) falls below the value of switch-on threshold HYS1. If the actual
value increases, integration is stopped.
If qeff exceeds the preset response threshold (q) (can be adjusted at the parameter level), this causes the second burner stage to
switch on or – in the case of the 3- position controller/modulating controller – the controlling element to open.
If the current boiler temperature reaches the required setpoint, qeff is reset to 0.
