Dynamis Max - Heat pumps for domestic
hot water heating
This unit is a heat pump for heating domestic water
in residential and small business premises. When
heating water, the heat pump also cools the area
from which the air is drawn and/or to which it re-
turns. The heat pump can therefore, be used for
cooling indoor spaces, but only if there is a need to
heat domestic water at a given time.
îIn order to achieve the highest
eciency and savings, we recommend that
air from rooms with waste heat (boiler room,
laundry, kitchen, cellar, pantry) is used as the
heat source and that the air temperature is
as high as possible.
The appliance consists of a generator (compres-
sor, evaporator, fan, ...) and a hot water tank. The
generator housing is made of durable plastic and
is thermally and acoustically insulated. The unit has
two air duct attachments that allow remote air in-
take and exhaust from adjacent rooms or from the
environment. The hot water tank is equipped with
a tubular heat exchanger that can be connected to
an external boiler powered by fossil fuel, biomass or
solar energy.
Components description
Domestic Hot Water Tank
The domestic water heater is enamelled with pat-
ented technology, thermally insulated with polyure-
thane and mechanically protected with sheet metal.
The tank is equipped with a water heat exchanger
as standard, which can be connected to the boiler
if an additional heat source is selected. The tank is
also equipped with an Mg anode which prevents the
heater from corrosion in case of possible mechani-
cal damage to the enamel.
Heating Element
The appliance is serially equipped with two 2 x 2 kW
electric heaters which serve as additional or reserve
heating source. Together with both already installed
heaters it is possible to install an additional heater
in the sanitary hot water tank by means of a 6/4”
connection with separate power supply.

Anti-freeze Probe
The heat pump controller senses the evaporator
temperature. If the evaporator temperature is be-
low -7 °C, the unit switches off safely for at least 30
minutes. In this case, heat pumps with an electric
heater automatically switch to electric heating, and
heat pumps with a connected boiler to boiler heat-
ing (switching on the circulation pump).
Safety Thermostat
The heating element is equipped with a safety ther-
mostat with a limit of 75°C. This means that if this
temperature is exceeded in the hot water tank, the
power will be switched off and the appliance will
stop working. In order to restart the unit, an author-
ised installer must be called to check and remedy
the cause of the safety shutdown.
îIn the case of heating with a boiler or
solar panels, the water in the hot water
cylinder may be heated to a temper-
ature above 75°C, causing the safety
thermostat to switch o. In this case
the thermostat must be reset manu-
ally. To restart the thermostat, call an
authorised installer.
Boiler Water Temperature Control
Monitoring and heating of the water to the desired
temperature is provided by the advanced OPTI-
TRONIC 2 controller. In relation to the set desired
water heating temperature, the controller switches
the compressor and fan on or off as required, and
under certain conditions also switches the heating
element or boiler circulation pump on or off. The
maximum water heating temperature that can be
set is 65°C. If the temperature in the hot water tank
rises above 75°C, the controller will switch off all
heat sources for safety reasons. The minimum wa-
ter temperature in the hot water tank is 7 °C.
High Pressure Cooling System Protection
To prevent excessive pressure in the refrigeration
system and the associated potential damage, a
high-pressure safety pressure switch was installed,
which stops the heat pump from operating if the
pressure rises above a preset point.
