Anti- freezing
• When the unit is stopped during shut-off periods and the ambient temperature is very low, the water inside the pipes and
the circulating pump may freeze, thus damaging the pipes and the water pump. In these cases, the installer shall ensure
that the water temperature inside the pipes does not fall below the freezing point. In order to prevent this, the unit has a
self-protection mechanism which should be activated.
• Frost can damage the system. To prevent the hydraulic components from freezing, the software is equipped with special
frost protection functions such as water pipe freeze prevention and drain prevention (see the installer reference guide)
that include the activation of pump in case of low temperatures.
However, in case of a power failure,these functions cannot guarantee protection.
