REMKO CMF 320 Duo - Manual (Page 11)

The role of the indoor unit of the
CMF 320 Duo Inverter Heat Pump
is to convert the condensation heat
supplied by the outdoor unit for
use on the heating side. The indoor
unit is therefore equipped with a
charge pump and a safety module
on the water side. Furthermore, an electrical booster
heater can be incorporated as an
option. The CMF 320 Duo can
be used both for monoenergetic
and bivalent operation. Bivalent
operation means the use of the
heat pump with a second fully-
fledged heat generator (boiler). The CMF 320 Duo always requires
an external storage tank, in order to
guarantee good control behaviour
and a minimum water volume
for defrost energy. The required
size and type of storage tank are
dependent first and foremost on
the output of the second heat
generator, and on any additional
system components (e.g. solar
energy system, solid-fuel boiler).
