3.3. ABSENCE mode operation
This mode allows for energy savings and protects the tank during an extended absence: the control maintains the
water above 15°C and protects against corrosion.
When changing mode from the absence mode, the heater will perform heating to prevent Legionella contamination if
the absence lasted more than two days.
By default, the product will automatically perform an anti-legionella heating (heating up to the
maximum set point temperature) every 30 days or when a risk of proliferation is detected.
If any malfunction or air temperature outside the operating range of the heat pump (5°C to 35°C) is
detected by the appliance, the electric booster pump will be used to ensure minimal amount of
domestic hot water.
