Heating by two units of resistors
If the machine is configured with two units of resistors, the regulation takes place by
st
modulating the command of the 1 unit of resistor as in the case of a single unit, while the
2nd unit of resistor remains in operation if the temperature is lower than the one programmed,
nd
and it goes off upon reaching it. The 2 unit of resistor engages again after a hysteresis
which may be chosen (see "Programming of parameters").
In order to indicate that the heating is active, when the two heating units are in operation the
decimal point of the units of temperature is on and fixed, while when a single unit is in
operation, the decimal point flashes.
heating by gas burner
If the heating takes place by a gas burner, the machine is equipped with a special electronic
device that controls the lighting and the burner control. The microprocessor directly controls
the gas lighter when the temperature is lower than the one programmed.
The reset of the gas device is described on the alarms pages.
In order to indicate that the heating is active, the decimal point of the temperature units is lit.
The section entitled "Alarm procedures" describes the procedure to be adopted if there is no
flame.
Heating by indirect steam
If the heating takes place by indirect steam, no regulation is carried out by the machine
(the temperature is directly in proportion to the steam supply pressure of the machine).
The microprocessor simply indicates the cylinder temperature but is not able to act on the
heating.

INEFFICIENT SUCTION (AL1)
The alarm is only controlled if the card is configured with gas heating.
