Explanation
In the evaporator, energy is retrieved from the outdoor air and the
refrigerant that passes through the air heat exchanger is heated
and evaporates into a gas. (See section "2 About your heat pump"
for further information).
The compressor raises the temperature and pressure of the refri-
gerant. (See section "2 About your heat pump" for further informa-
tion).
In the condenser, the refrigerant supplies its heat energy to the
heat transfer fluid circuit. (See section "2 About your heat pump" for
further information).
The CURVE value is set via the display. The set value indicates the
supply line temperature of the water that is transported to the
radiators at an outside temperature of 0°C.
Is the circuit in the heat pump that through evaporation, compres-
sion and condensation takes energy from the outdoor air and supp-
lies it to the heat transfer fluid circuit. (See section "2 About your
heat pump" for further information).
Is the fluid/gas that transports heat from the air heat exchanger and
supplies it to the heating system. (See section "2 About your heat
pump" for further information).
Heater element, element.
If ROOM shows 20 °C the heat curve is unaffected. If ROOM shows
higher or lower, this indicates that the heat curve has been adjusted
up or down to change the indoor temperature.
The control computer controls the entire heating installation. All
settings are stored and the history of the installation is registered
here. The control computer's settings can be changed via the dis-
play.
The fluid circuit obtains heat/energy from the refrigerant circuit,
which it then transports to the water tank or heating system. See
section "2 About your heat pump" for further information.
The control computer determines the correct temperature of the
water to be distributed to the heating system based on the heat
curve. The indoor temperature is adjusted by changing the gradient
of the heating system's CURVE.
