10 Operating principle of heat
pumps
Heat pumps operate on the same principle as a
refrigerator: same technology, only with reversed
benets. The refrigerator extracts heat from foods,
which is released into the room through ns on the
back.
The heat pump extracts heat from our environment:
air, earth or ground water. The extracted heat is
conditioned in the unit and supplied to the heating
water. Even when it is extremely cold outside, the heat
pump draws enough heat to heat a house.
Example: drawing of a brine/water heat pump with
oor heating:
4⁄4= usable energy
approx. 3⁄4= environmental energy
approx. 1⁄4= external electrical
energy
11 Area of utilisation
Taking into consideration the ambient conditions, limits
of application and the applicable regulations, every
heat pump can be utilised in new or existing heating
systems.

12 Heat metering
In addition to proof of the unit’s e󰀩ciency, the
EEWaermeG also requires heat metering (hereafter
referred to as HQR). Heat metering is mandatory for
air/water heat pumps. Heat metering for brine/water
and water/water heat pumps only have to be installed
for a ow temperature ≥ 35 °C. The heat metering must
record the total thermal energy released (heating and
domestic hot water) in the building. In heat pumps
with heat metering, the analysis is carried out by the
regulator. The regulator displays the thermal energy
discharged in the heating system in kWh.
13 Operation
Your decision to purchase a heat pump or a heat
pump system is a long-term contribution to protecting
the environment through low emissions and reduced
primary energy use.
To ensure that your heat pump or heat pump system
operates e󰀩ciently and ecologically, the following are
especially important:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.A
lower ow temperature on the hot water side
increases the e󰀩ciency of the system.
€ENERGY SAVING TIP
Preferably use purge ventilation. Compared
to continuously open windows, it is better to
air rooms by fully opening windows for a short
period, two to three times a day (so-called
“rapid” or “purge” ventilation); this reduces
energy consumption and your heating bill.
You can operate and control the heat pump system
with the control element of the heating and heat pump
regulator.
NOTE
Make sure that the control settings are
correct.
Operating manual of the heating and heat
pump regulator
14 Cooling
There are two ways to use the heat pump for air con-
ditioning in rooms, through: „passive cooling“ and „ac-
tive cooling“.
The main di󰀨erence is the compressor operation.
While the compressor is not needed for passive cool-
ing, i.e. it is passive, the compressor operates during
active cooling, i.e. it is active.
Another di󰀨erence is that both passive and active
cooling is possible with the ground and groundwater
heat sources. But only active cooling is possible with
the outside air heat source.
Passive cooling is the more cost-e󰀨ective option. Low-
ering the temperature by 3-4 K is often fully su󰀩cient
to produce a comfortable room temperature in the
summer.
Whereas higher cooling output is possible with active
cooling.
Passive cooling uses the fact that the ground and
groundwater, from a depth of around 8 metres, are
more or less a constant temperature all year round
and in the summer are around 9 °C to 10 °C cooler
than the outside air or the interior rooms.
This temperature di󰀨erence is su󰀩cient to cool a build-
ing with energy from the ground and groundwater. Ad-
ditional fan coils, cooling ceilings, underoor heating
and thermo active building systems (embedding cool-
ing pipes), such as concrete core thermal activation,
can be used for direct cooling.
ATTENTION
By cooling with low ow temperatures, con-
densate can be expected to form on the heat
distribution system as the temperature falls
below the dew point. If the heat distribution
system is not designed for these operating
conditions, it must be protected by appro-
priate safety devices, e.g. dew point monitor
(purchasable accessory).
NOTICE
If the heating surfaces are used for heating
and cooling, the control valves must be suita-
ble for heating and cooling.
In addition, a dew-point monitor should be
used for cooling.
NOTE
Use recommended accessory dew point
monitors.

The room thermostat of the cooling function
(purchasable accessories, optional)
The room thermostat is used to release and to switch
o󰀨 the cooling function:
I Cooling function switched on
Cooling function o󰀨
USE OF THE COOLING FUNCTION
The heating and heat pump regulation program acti-
vates the cooling function only if the following condi-
tions are fullled:
●Heat pump type with integrated cooling function
●Room thermostat of the cooling function is
switched on
●Temperature of the heat source is ≥ +5 °C
●Heat pump is currently not being used for „heat-
ing“ nor for „domestic water heating“. If the heat
pump control program sends the “domestic wa-
ter heating” request to the heat pump, the cool-
ing function of the heat pump stops automati-
cally for the duration of the domestic water heat-
ing
●The „Automatic“ setting is selected under the
„Cooling mode“ heading
●The outside temperature release set at the con-
trol is exceeded
Operating manual of the heating and heat
pump regulator
The cooling function can be used in two variants:
Variant 1:
Manual switching from heating to cooling mode
(and vice versa). This uses a xed pre-set ow
temperature.
Operating manual of the heating and heat
pump controller.
Variant 2:
Automatic switching from heating to cooling
mode (and vice versa). This variant can operate
using a cooling curve.
NOTE
Variant 2 is only possible if the expansion
board (purchasable accessories) is installed
in the heating and heat pump controller.
Expansion board operating manual
15 Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and standard cleaning products.
Do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy the surfaces and could also damage the
technical components of the unit.
16 Maintenance of the unit
The cooling circuit of the heat pump requires no regu-
lar maintenance.
According to EU regulation (EC) 517/2014, leak
inspections and maintenance of a log book are
required by law for certain heat pumps!
Log book for heat pumps, Section “Information
on use of the log book”
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
lters, dirt traps) should be inspected and cleaned
as needed - at the very least annually - by qualied
personnel (heating or cooling system tters).
It is best to arrange a maintenance agreement with
a heating installation company. The company will
arrange for the required maintenance at regular
intervals.
