3.2 CMF series
We offer two different indoor-unit designs. The
wall-mounted CMF series is equipped with a circu-
lation pump and a safety module on the water side.
Furthermore, an electrical booster heater can be
incorporated as an option. The CMF series was
constructed for the addition of several heat
sources (bivalent installations or systems with
solar-heating equipment). External buffer storage
is always required, its size depending on the type
and the power of the second heat source. On the
one hand, the buffer storage prevents short run-
times for the heat pump and on the other hand,
that sufficient defrosting energy is available.

3.3 CMT series
In addition, the indoor module of the CMT series is
fitted with a hot-water buffer storage. An electric
booster heater with a max. output of 9 kW is
standard. The hot-water buffer-storage has a
capacity of 160 litres and is integrated as a
hydraulic switch. As a result, the CMT series is the
ideal equipment when the heat pump is intended
as the sole heat source (single energy-source ope-
ration). A heating circuit pump must be mounted
on site.
