This accessory is used for F370/F470 to enable connection
and control of external heat sources as follows:
႑
DEH40:
႑
Wood-fired boiler
႑
Oil boiler
႑
Multifunction tank
႑
DEH41:
႑
Gas boiler
The heat pump ventilates the building and recovers en-
ergy from the ventilation air. The heat is used to heat the
building and the hot water.
Normally additional output occurs via the heat pump’s
immersion heater in the event that the heat pump output
is not sufficient.
The above alternative gives this additional output using
external heat sources. If the power is not available in the
external heat source the immersion heater is automatically
engaged.
In order to dock an external heat source the heat pump
must be supplemented with two docking pipes, which
are included in the docking kits DEH40/41.
NOTE
When this accessory is installed and activated
the temperature in the heat pumps vessel is
limited to about 60 °C. Therefore, temperature
settings regarding hot water or heating must
not exceed 60 °C.
