Pipe installation
Docking alternatives
Heating system can be constructed in several different ways
combining indoor unit, tank, control unit and other accessories.
For further option information, see page 73.
In the system example shown on the following page, heating,
hot water as well as cooling operation are available.
Additional heating is helpful on the cold day of the year as the
energy from the air is reduced. It is also recommended as back-
up in case the heat pump operation is blocked for any reason
(e.g. ambient temperature exceeds the operation limit of heat
pump).
NOTE
The heating medium side and the hot water side must be
fitted with the necessary safety equipment in accordance
with the applicable regulations.
This is the outline diagram. Actual installations
must be planned according to applicable
standards.
