The monobloc system consists of one unit that is installed outdoors and
can be connected directly to the heating circuit. Control is by means of
a wired controller inside the building.
the monobloc system is in danger of freezing when the heating circuit is
filled with water and the outside temperature decreases below 0 °C!
This can lead to substantial damage to the unit.
Freedom from frost must be ensured within the heating system through
one of the following options:
1. The heating circuit is operated with a foodgrade frost protection
mixture (propylene glycol).
2. An auxiliary electric heater inside the Monobloc unit prevents the
heating circuit from freezing.
3. The heating circuit is emptied via an owner-provided device
(manually or automatically).
