How heat pumps work
Heat pumps operate on the same principle as a refrigerator:
the same technology, only with reversed benets. The
refrigerator extracts heat from food, It discharges this heat
into the room through ns at its rear.
The heat pump extracts heat from our environment: from
the air, earth or water.The extracted heat is conditioned in
the unit and passed on to the heating water. Even when it is
extremely cold outside, the heat pump draws enough heat
to heat a house.
Example: sketch of a brine/water heat pump with underoor
heating:
4/4= useful energy
approx. 3/4= environmental energy
approx. 1⁄4= external
electrical energy
Area of use
Taking into consideration the ambient conditions, limits of
use and the relevant regulations, any heat pump can be used
in new or existing heating systems.
“Technical data /scope of supply” overview.
Heat metering
In addition to proof of the unit's efciency, the EEWaermeG
(German law promoting renewable energy for heating) also
requires heat metering (hereinafter referred to as WME).
Heat metering is mandatory for air/water heat pumps. Heat
metering for brine/water and water/water heat pumps only
has to be installed for a ow temperature ≥35 °C.The heat
metering must record the total thermal energy output
(heating and hot water) to the building. In heat pumps with
heat metering, the evaluation is carried out by the controller.
The controller displays the thermal energy output into 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.
You use the control element of the heating and heat pump
controller to operate and control the heat pump system.
NOTE.
Make sure that the controller settings are correct.
Operating manual of the heating and heat pump
controller.
To ensure that your heat pump or heat pump system oper-
ates efciently and ecologically, please pay particular atten-
tion to the following:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.
The lower the ow temperature on the heating
water side the more efcient the system.
€ENERGY SAVING TIP
Preferably use purge ventilation. Compared to con-
tinuously open windows, it is better to air rooms
by fully opening windows for a short period, two
to three times a day (so-called “purge” ventilation);
this reduces energy consumption and your heating
bill.

Care of the unit
You can use a damp cloth and standard cleaning products to
clean the outer surfaces of the unit.
Do not use cleaning or care products that contain abrasives,
acids and/or chlorine. Such products would irreparably
damage the surfaces and could also cause technical damage
to the unit.
Maintenance of the unit
The cooling circuit of the heat pump requires no regular
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, circulation pumps, lters, dirt
traps) should be checked and cleaned as necessary, but at
least annually, by qualied personnel (heating or cooling
system tters).
The intake and discharge openings must be checked for dirt
at regular intervals (depends on where the unit is installed)
and cleaned if necessary.
ATTENTION
Check regularly to ensure that the condensate can
drain out of the unit freely, without obstruction.To
this end, check the condensate pan in the unit and
the condensate drain regularly for dirt / blockages
and clean as necessary.
Icing of the protective grating
If temperatures fall below freezing and high levels of
humidity are present, ice can form on the protective grating
of the air deector hoods. In order to ensure fault-free
operation, the ice must be removed regularly!
It is best to sign a maintenance agreement with a heating
installation company. It will arrange for the necessary
maintenance work at regular intervals.
CLEANING AND FLUSHING UNIT COMPONENTS
CAUTION!
Unit components may be cleaned and
ushed only by customer service personnel
authorised by the manufacturer. Only use
liquids recommended by the manufacturer.
After ushing the condenser with chemical
cleaning agent, any residues must be neu-
tralised and the system ushed intensively
with water. Always note and follow the tech-
nical data of the respective heat exchanger
manufacturer.
Malfunctions
In the event of a fault, you can read out the cause of the
fault from the diagnostic program of the heating and heat
pump controller.
Operating manual of the heating and heat pump
controller.
WARNING!
Only customer service personnel authorised
by the manufacturer may carry out service
and repair work on the components of the
unit.
Note that no fault is displayed if the safety temperature
limiter on the electric heating element has triggered
(depending on model).
“Commissioning”, “Safety temperature limiter”
