12 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 following
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.
13 Operation
Energy saving use of the heat pump heating
By deciding to purchase a heat pump or a heat pump
system you are making a long-term contribution to
protecting 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
controller.
NOTE
Make sure that the control settings are cor-
rect.
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 heat
-
ing water side the more efficient the system.
€
ENERGY SAVING TIP
Preferably use purge ventilation. Compared
to continuously open windows, this form of
ventilation (fully opening windows for a short
period, two to three times a day) reduces
energy consumption and your heating bill.
14 Care of the unit
You can clean the outer surfaces of the unit with a
damp cloth and proprietary household cleaning prod-
ucts.
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.
15 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,
filters, dirt traps) should be tested and cleaned as
needed, however, at least annually, by qualified per
-
sonnel (heating 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.
15.1
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.
