Start-up, calibration and operation of the burner

Reset procedure

Manual lockout procedure

If necessary, it is possible to manually block the control box and, consequently, the burner, by pressing the key “i/reset“ simultaneously

with any other key of the Operator Panel.

The burner is in lockout when the red indicator light on the Operator Panel is switched on

and the display visualises alternately the lockout code (in the example alongside c: 4) and

the relative diagnostic (in the example d: 3).

To reset, press the “i/reset” key for 1s: the display will show “rESEt”.

When the key is released, the lockout signal will disappear and the red indicator light will

switch off.

The control box is reset.

With the switch 1-0 in Fig. 28 the burner does not stop immediately, but the switch-off phase is activated.

CAUTION

Manual operation procedure

After the adjustment of the burner and the setting of the points on

the modulation curve, it is possible to manually check the opera-

tion of the burner along the entire curve.

Example

To emerge from Manual mode, press simultaneously the keys

“+” and “-” (esc) for 3 seconds: the burner will work in auto-

matic mode and the output will depend on the thermostat/adjust-

ment pressure switch (TR).

The burner is working at

the requested load per-

centage: 20%.

Press the key “F” for 1

second: “LoAd” is dis-

played and the load per-

centage flashes.

Releasing the key “F”, the

standard visualisation

appears, with the current

load percentage flashing:

this means that the burner

is working in manual mode

(any outside adjustment is

excluded and only the

safety devices are active).

Keep the key “F” pressed

and, with the keys “+” or

“–”, increase or decrease

the load percentage.
