HRV support FAQ

Common questions about manuals, registration, and support for this brand.

  • How often should I replace my HRV filter?

    It is recommended to check and replace your HRV system filter every 2 years to ensure optimal performance and air quality. Some models may suggest a check every 6 months depending on usage.

  • What do the ventilation levels on the keypad mean?

    Ventilation levels allow you to adjust airflow based on the season. Levels 1-3 are generally used for spring, summer, and autumn. Higher levels (3-6) are recommended for winter to help clear condensation when the roof cavity temperature is cooler.

  • What is Burnt Toast mode?

    Burnt Toast mode overrides the system to run the fan at 100% speed for one hour. This is useful for quickly clearing odors, smoke, or excessive condensation.

  • Why is my Filter Replacement light on?

    This icon illuminates based on a timer to remind you that the system is due for a filter change or service, typically every 24 months. Once the filter is changed, the indicator can be reset via the keypad menu.
