Quick answer

Immergas 62 means full calibration is missing on the Victrix Omnia V2, so the boiler cannot start. Give the technician details of any board replacement or air/gas setting changes; do not enter calibration menus.

Safety first

Stop and check this first

  • If you smell gas while investigating 62, leave the home without operating switches or creating sparks; avoid flames and smoking, close the main gas valve if safe and call the gas emergency service from outside.
  • Calibration for code 62 generates heat and changes combustion regulation; it remains gas technician work even though panel buttons initiate it.
  • Alongside warning 62, a CO alarm or headache, dizziness or nausea requires moving outside into fresh air and calling emergency services; do not wait for boiler lockout or re-enter until cleared to do so.

Safe checks you can perform

  • Identify warning 62
  • Prepare the installation history
  • Establish why calibration is required

Leave these tasks to a qualified professional

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Establish why calibration is required

    What they doA qualified gas technician checks whether the board was replaced or air/gas parameters changed and prepares the prescribed calibration.

    They must show youthe work that requires calibration and the model identification.

    In writingthe previous changes found and applicable procedure.

  2. Full calibration and combustion verification

    What they doThe technician completes the manual calibration stages, verifies CO2 and allows automatic verification to finish without interruption.

    They must show youthe combustion measurements and completion of the process.

    In writingthe readings compared with the manual and commissioning outcome.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Identify warning 62

    No special tools

    Who:
    you.
    How:
    Record the displayed 62 and keep the report from the latest board replacement or combustion-setting work.
    What matters: A link with replacement or adjustment helps the technician distinguish unfinished commissioning from other lockouts.
    If the warning persists:
    request service with the complete code and model.
    If it has cleared:
    retain the record and report any recurrence.
    Evidence to keep:
    dated photograph of 62.

  2. Prepare the installation history

    No special tools

    Who:
    you.
    How:
    Use your paperwork to identify the Victrix Omnia V2 and recent work; leave any service-password entry to the maintenance professional.
    What matters: Installation history guides inspection but does not replace professional checks.
    If the warning persists:
    give this history to the qualified gas service company.
    If it has cleared:
    retain the record and report any recurrence.
    Evidence to keep:
    documents relating to Victrix Omnia V2 and 62.

  3. Establish why calibration is required

    Tools required

    Who:
    qualified gas installation technician.
    How:
    A qualified gas technician checks whether the board was replaced or air/gas parameters changed and prepares the prescribed calibration.
    What matters: The diagnosis must explain 62 using a verifiable check.
    If the warning persists:
    the professional completes diagnosis before signing off the repair.
    If it has cleared:
    retain the record and report any recurrence.
    Evidence to keep:
    the previous changes found and applicable procedure.

    Internal inspection of Victrix Omnia V2 is restricted to qualified professionals; keep the casing closed.

What it means

Omnia V2 records 62 when the electronic board has not been calibrated. Immergas identifies board replacement and changes to air/gas section parameters as situations requiring full calibration. The professional procedure includes nominal, intermediate and minimum output stages followed by an automatic verification. Missing calibration prevents starting and does not prove that a replacement board is defective.

Symptoms and causes

Probable causes · in order

  • Replacement board awaiting calibrationPossible

    Replacing the board can leave the full calibration required by Immergas outstanding before operation can resume.

    Evidence: Immergas Victrix Omnia V2, instrucciones y advertencias para instalador, usuario y encargado de mantenimiento (1.047702SPA)

  • Air/gas parameters alteredPossible

    Certain parameter changes in the air/gas section require another full calibration even when the electronic board has not been replaced.
