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
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.

Heat metering
In addition to proof of the unit’s ef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.
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 ef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 ef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.
Cooling
There are two ways to use the heat pump for air condi-
tioning in rooms, through: „passive cooling“ and „active
cooling“.
The main difference is the compressor operation. Whi-
le the compressor is not needed for passive cooling, i.e.
it is passive, the compressor operates during active coo-
ling, i.e. it is active.
Another difference is that both passive and active coo-
ling is possible with the ground and groundwater heat
sources. But only active cooling is possible with the out-
side air heat source.
Passive cooling is the more cost-effective option. Lowe-
ring the temperature by 3-4 K is often fully sufcient to
produce a comfortable room temperature in the sum-
mer.
Whereas higher cooling output is possible with active
cooling.
Passive cooling uses the fact that the ground and ground-
water, 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 out-
side air or the interior rooms.
This temperature difference is sufcient to cool a buil-
ding with energy from the ground and groundwater. Ad-
ditional fan coils, cooling ceilings, underoor heating and
thermo active building systems (embedding cooling pi-
pes), such as concrete core thermal activation, can be
used for direct cooling.
ATTE NTION
By cooling with low ow temperatures, conden-
sate can be expected to form on the heat distri-
bution 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 appropriate 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 suitable for
heating and cooling.
In addition, a dew-point monitor should be used
for cooling.
NOTE
Use recommended accessory dew point moni-
tors.

THE ROOM THERMOSTAT OF THE COOLING FUNCTION
(PURCHASABLE ACCESSORIES, OPTIONAL)
The room thermostat is used to release and to switch
off the cooling function:
I Cooling function switched on
Cooling function off
USE OF THE COOLING FUNCTION
The heating and heat pump regulation program activates
the cooling function only if the following conditions are
fullled:
•Heat pump type with integrated cooling function.
•Room thermostat of the cooling function is swit-
ched on.
•Temperature of the heat source is ≥ +5 °C.
•Heat pump is currently not being used for „heating“
nor for „domestic water heating“.If the heat pump
control program sends the “domestic water hea-
ting” request to the heat pump, the cooling function
of the heat pump stops automatically for the dura-
tion of the domestic water heating.
•The „Automatic“ setting is selected under the
„Cooling mode“ heading.
•The outside temperature release set at the control
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 hea-
ting and heat pump controller.
Expansion board operating manual
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.
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.
