CUT OFF BOILER TEMPERATURE PROBE
This alarm does not block the machine.
This alarm intervenes when the boiler temperature sensor is interrupted.
The alarm is visualised on the display for 5 minutes and is then substituted by the flashing
symbol that signals the presence of
a malfunction in the machine.
When the temperature sensor is faulty, the thermostat regulation of the machine is taken over by the pressure sensor that recovers
the pressure value corresponding to the set temperature value previously memorised during the programming phase (or correspond-
ing to the last compensated temperature value) and maintains the temperature constant.
During this phase, the machine continues to function and it is not possible to modify the reference pressure value.
SHORT CIRCUITED BOILER TEMPERATURE PROBE
This alarm does not block the machine.
This alarm intervenes when the boiler temperature sensor is short-circuiting.
The alarm is visualised on the display for 5 minutes and is then substituted by the flashing
symbol that signals the presence of
a malfunction in the machine.
When the temperature sensor is faulty, the thermostat regulation of the machine is taken over by the pressure sensor that recovers
the pressure value corresponding to the set temperature value previously memorised during the programming phase (or correspond-
ing to the last compensated temperature value) and maintains the temperature constant.
During this phase, the machine continues to function and it is not possible to modify the reference pressure value.
HIGH BOILER TEMPERATURE
This alarm intervenes when the boiler temperature sensor detects a temperature greater than 130°C.
When this alarm intervenes, the machine is disconnected from the electrical mains supply by a circuit breaker switch.
The alarm resets when the temperature detected by the sensor re-enters within the normal parameters.
BOILER TEMPERATURE NOT REACHED
This alarm does block the machine.
This alarm intervenes when the temperature detected by the sensor in the boiler has not yet reached 50°C. 20 minutes after switch-
ing on (either in manual mode or in TIMER mode).
