Why Lamborghini Caloreclima ALHENA TECH 28 H Boiler has no burner ignition?
- C
  Catherine ContrerasAug 17, 2025
  The Lamborghini Caloreclima Boiler might not ignite due to several reasons: * There is no gas flow: check the regular gas flow to the boiler and ensure that the air has been eliminated from the pipes. * Faulty ignition/detection electrode: check the wiring and positioning of the electrode, ensure it's free of deposits, and replace if needed. * Insufficient gas supply pressure: check the gas supply pressure. * Blocked trap: check the trap and clean if necessary. * Obstructed air/fume ducts: remove any obstructions from the flue, fume extraction ducts, air inlet, and terminals. * Wrong calibration: perform the Calibration procedure [AUTO SETUP]. * Faulty gas valve: check the gas valve and replace if necessary.

What to do if Lamborghini Caloreclima ALHENA TECH 28 H has no flame after the ignition phase?
- M
  Matthew PorterAug 19, 2025
  If your Lamborghini Caloreclima Boiler fails to ignite after the ignition phase, the issue might stem from: * A faulty ionization electrode: inspect its position, clear any encrustations, and perform the Calibration procedure [AUTO SETUP]. Replace the electrode if needed. * Unstable flame: check the burner. * Obstructed air/fume ducts: clear any obstructions from the flue, fume extraction ducts, air inlet, and terminals. * Blocked trap: check and clean the trap if necessary. * Wrong calibration: perform the Calibration procedure [AUTO SETUP]. * Insufficient gas supply pressure: check the gas supply pressure.

Why Lamborghini Caloreclima ALHENA TECH 28 H activates overtemperature protection?
- G
  Gabrielle NelsonAug 22, 2025
  The overtemperature protection in your Lamborghini Caloreclima Boiler may be triggered by: * Incorrectly positioned or damaged flow or return sensors: check their positioning and operation, replacing them if necessary. * Lack of water circulation in the system: check the circulating pump. * Air present in the system: vent the system to remove trapped air.

What causes specific combustion control errors in Lamborghini Caloreclima ALHENA TECH 28 H?
- C
  cartercatherineAug 25, 2025
  Specific combustion control errors in your Lamborghini Caloreclima Boiler can arise from: * Obstructed fume ducts, low gas pressure, blocked condensate trap, fumes recirculation, or combustion problems: check that the fume ducts and condensate trap are clear, verify the gas supply pressure, perform CO adjustment in TEST mode, and if needed, perform the Calibration procedure [AUTO SETUP].

What to do if Lamborghini Caloreclima ALHENA TECH 28 H shows flame present signal with burner off?
- K
  Katrina BellAug 27, 2025
  If your Lamborghini Caloreclima Boiler indicates a flame is present even when the burner is off, consider these potential causes: * Electrode fault: check the ionization electrode wiring and condition. * Electrode to ground. * Cable to ground. * Blocked trap: check the trap and clean it if necessary. * Card fault: check the card.

What to do if my Lamborghini Caloreclima Boiler exchanger protection intervention?
- J
  Jasmine CalderonAug 30, 2025
  The exchanger protection in your Lamborghini Caloreclima Boiler might activate due to: * No water circulation in the system: check the circulating pump and heating system. * Poor circulation and anomalous flow probe temperature increase: vent the system. * Blocked exchanger: check the exchanger and system.
