Heat metering
In addition to proof of the system's efficiency, the
EEWaermeG (German law on renewable energy heat)
also requires heat metering (referred to in the follow-
ing as WME). The WME is mandatory for air/water heat
pumps. For brine/ water and water/water heat pumps, a
WME must be installed for flow temperatures ≥ 35 °C.
The WME must record the total thermal energy output
(heating and domestic hot water) in the building. In the
case of heat pumps with heat metering the analysis is
carried out via the controller. This displays the thermal
energy output into the heating system in kWh.
NOTE.
Unit variants with or without heat metering are
available.
Operation
ENERGY SAVING USE OF THE HEAT PUMP HEATING
By deciding to purchase a heat pump or a heat pump sys-
tem you are making a long-term contribution to protect-
ing the environment through low emissions and reduced
primary energy use.
You can operate and control the heat pump system with
the control panel of the heating and heat pump control-
ler.
NOTE.
Make sure that the control settings are correct.
Operating manual of the heating and heat pump
controller.
To ensure that your heat pump or heat pump system
operates efficiently and in an environmentally friendly
way in heating mode, please pay particular attention to
the following:
€
ENERGY SAVING TIP
Avoid unnecessarily high flow temperatures.
The lower the flow temperature on the heating
water side the more efficient the system.
€
ENERGY SAVING TIP
Preferably use purge ventilation. Compared to
continuously open windows, this form of ventila-
tion (fully opening windows for a short period,
two to three times a day) reduces energy con-
sumption and your heating bill.
Care of the unit
You can clean the outer surfaces of the unit with a damp
cloth and proprietary household cleaning products.
Do not use cleaning or care products that contain abra-
sives, acids and/or chlorine. Such products would irrepa-
rably 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 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, circulation pumps, fil-
ters, dirt traps) should be tested and cleaned as needed,
however, at least annually, by qualified personnel (heat-
ing or refrigerating system fitters).
It is best to arrange a maintenance agreement with a
heating installation company. The company will arrange
the necessary regular maintenance work.
CLEANING AND FLUSHING UNIT COMPONENTS
CAUTION!
Unit components may be cleaned and
flushed only by customer service person-
nel authorised by the manufacturer. Use
only liquids recommended by the manu-
facturer.
After flushing the condenser with chemi-
cal cleaning agent, any residues must be
neutralised and the system intensively
flushed with water. Always note and follow
the technical data of the respective heat
exchanger manufacturer.
