Both versions are delivered with an integrated backup heater for
additional heating capacity during cold outdoor temperatures. The
backup heater also serves as a backup in case of malfunctioning of
the unit and for freeze protection of the outside water piping during
winter time. The backup heater factory set capacity is 6 kW, however,
depending on the installation, the installer can limit the backup heater
capacity to 3 kW. The backup heater capacity decision is a mode
based on the equilibrium temperature, see scheme below.
