If an external passive cooling system is installed in your
system:
a Caution!
Danger of falling below the dew point and
condensate formation!
The heating flow temperature setting
must not be too low in cooling mode. The
cooling function is still effective with a
flow temperature of 20 °C.
a Caution!
The cooling function is impaired if the
thermostatic radiator valves are closed!
The thermostatic radiator valves must
be switched to the "open" position in
cooling mode to ensure that the cooled
heating water circulates smoothly
through the underfloor circuit.
2.2 Prohibition on alterations
d Danger!
Inappropriate alterations can cause
injuries!
Under no circumstances should you
attempt to make changes or alterations
to the heat pump or other parts of the
heating and hot water system yourself.
The prohibition applies to:
— the heat pump,
— the vicinity of the heat pump,
— the supply lines for water and power.
For alterations to the heat pump or its peripherals, you
must call on a qualified engineer.
• Do not damage or remove seals or locking devices on
components. Only suitably qualified heating engineer
or our customer service may remove sealed compo-
nents.

3.1 Functional principle
Heat pump systems consist of separate circuits in which
liquids or gases transport the heat from the heat source
to the heating system. As these circuits operate with
differing media (brine/water, coolant and heating
water), they are coupled to one another by means of
heat exchangers. In these heat exchangers the heat
passes from a medium at a high temperature to a
medium at a lower temperature.
The Vaillant geoTHERM heat pump uses geothermal
energy or ground water as its heat source.

Fig. 3.1 Use of geothermal energy or ground water as the heat
source
The system consists of separate circuits which are cou-
pled to one another by means of heat exchangers.
These circuits are:
- The heat source circuit, by means of which the energy
from the heat source is transported to the coolant
circuit.
- The coolant circuit, which releases its heat to the
heating water circuit by means of evaporation, com-
pression, liquefaction and expansion.
- The heating water circuit, which supplies the heating
and the hot water generation for the domestic hot
water cylinder.
