3.5.2 Economising by the correct use of the control
system
Further economies can be made by the correct use of
the control system on your heat pump.
The control of the heat pump helps you to make savings
by:
— The correct selection of the heating flow temperature:
Your heat pump controls the heating flow tempera-
ture depending on the room temperature you have
set. Therefore select a room temperature that is just
sufficient for your comfort, for example 20 °C. Every
degree over and above that means an increase in en-
ergy consumption of around 6 % per annum.
— For floor heating use heating curves of < 0.4. For radi-
ator heating, we recommend that they are laid out to
manage with a maximum flow temperature of 50 °C
at the lowest outside temperature; this corresponds to
heating curves of < 0.7.
— An appropriate setting of the hot water temperature:
Only heat hot water as much as is required for con-
sumption. Any further heating results in unnecessary
power consumption, and hot water temperatures of
more than 60 °C also lead to increased lime scale pro-
duction. We recommend that hot water generation be
achieved without the electric auxiliary heating; by this
method, the maximum hot water temperature is de-
termined by the high pressure cut-out in the heat
pump cooling circuit. This cut-out corresponds to a
maximum hot water temperature of approx. 58 °C.
— Setting of individually suited heating times.
— Select the correct operating mode:
For the times that you are asleep or away, we recom-
mend that you switch the heating to set-back mode.
— Heat uniformly:
By means of a meaningfully constructed heating pro-
gramme, you can arrange for all the rooms in your
house to be uniformly heated in accordance with your
pattern of use.
— Set the thermostatic valves:
You can adjust the room temperature to suit your in-
dividual requirements and ensure effective operation
of your heating installation using the thermostatic
valves in combination with a room temperature regu-
lator (weather compensator).
— The operating times of the circulation pump can thus
be optimally matched to the actual need.
— Consult a qualified engineer. He will adjust your heat-
ing installation to suit your personal requirements.
— You will find these and other energy saving tips in
Chap. 5.5. The controller settings that can potentially
save energy are described there.

Recycling and disposal

Both your heat pump and all its accessories and associ-
ated transport packaging consist overwhelmingly of raw
materials that can be recycled, and thus have no place
in your household waste.
Note!
h
Please observe the applicable national
legal regulations.
Make sure the old appliance and any ac-
cessories are disposed of properly.
Caution!
a
Environmental hazard due to improper
disposal!
The disposal of coolant must only be by
qualified specialists.
3.6.1

Appliance

If your heat pump is identified with this sym-
bol, it does not belong with your household
waste at the end of its useful life.
As this heat pump is not covered by the law
regarding the marketing, return and environ-
mentally friendly disposal of electrical and electronic
equipment (ElektroG in Germany), free disposal at a mu-
nicipal collection point is not provided.

3.6.2 Packaging

Leave the disposal of the transport packaging to the
qualified servicing company which installed the appli-
ance.
3.6.3

Coolants

The Vaillant heat pump is filled with R 407 C coolant.
Danger!
d
Risk of injury from freezing as a result
of contact with the R 407 C coolant!
Escaping coolant can cause freezing if
the exit point is touched.
Do not inhale gases or vapours emanat-
ing from leaks in the coolant circuit.
Avoid contact with the skin and eyes.
The disposal of coolant must only be by
qualified specialists.
Note!
h
R 407 C presents no danger in normal
use and under normal conditions. With
improper use, however, it can cause inju-
ry and damage.
