Description Of Operation And Functions - Lamborghini Caloreclima Alma 24 MBS W TOP Manual De Uso

WARNINGS
For each operating mode one or more symbols appear on the LCD display.
In the event of a fault, the display will show a code whose meaning is summarised in the following table:
Fault
Failed ignition lock
Safety thermostat intervention lock
No water
Air pressure switch (MCS)/flue gas thermostat (MC)
NTC heating sensor fault
NTC sanitary water sensor fault
LOCK/RESET
If the boiler fails to ignite at the first attempt, there is an interventilation time and then a further two ignition attempts. For
LPG boilers only 1 ignition attempt remains active.
When this time has elapsed and ignition has failed, a non-volatile locking stop occurs (stored).
"Failed ignition lock 01" fault.
Reset the boiler by simultaneously pressing the P1 and P2 buttons. Remember that you can only reset the boiler a maximum
of 5 consecutive times both from the boiler control panel and from a remote control. After this, the boiler can only be reset:
- after 1h (1 additional reset every hour is permitted);
- by cutting the power.

DESCRIPTION OF OPERATION AND FUNCTIONS

HEATING MODE
The heating operating mode starts if requested by the ambient thermostat and if the operating selector is set to
"WINTER".
The circulator, fan (MBS) and switching valve are activated and, after checking that there is air flow, burner ignition is
requested.
When the "slow ignition time" from flame detection has elapsed, the burner power goes to the minimum value set and
reaches the maximum value within about 50 seconds.
The burner stops when the set heating temperature has been reached or when the ambient thermostat intervenes. The
intervention of the ambient thermostat also activates a post-circulation cycle (heating) after which the circulator is turned
off and the switching valve returns to the sanitary water position.
WATER HEATER ELECTRIC SWITCHING VALVE
The sanitary water mode with water heater starts when the water heater sensor reads a temperature lower than the "water
heater ON temperature". The switching valve is then driven into sanitary water position and the system pump is activated,
and both remain active even at the end of the water heater request for post-circulation. In the event of concurrent requests,
the water heater is given priority and at the end the switching valve is switched to heating and water heater post-circulation
is reset.
During operation in sanitary water mode, the switching valve relay remains in rest position.
