3.3 Functionally necessary
accessories
Only use genuine accessories made by the manufac-
turer of the device.
● Hydraulic station or
● Hydraulic module
3.4 Additional accessories
The following accessories are available via the manu-
facturer’s local partner:
● Wall duct or hydraulic connection line (each with
vibration decouplings)
● Wall bracket
● Floor bracket
● Vibration decouplings
● Air / magnetic sludge separator
● Buffer tank
● Overflow valve
● Cladding for wall bracket
● Cladding for floor bracket
● Extension board
● Room control panel for controlling the main func-
tions at the living quarters
● Cable extension kit
For reversible devices:
● Room thermostat for switching the cooling function
● Dew point monitor for protecting a system with
cooling function at low flow temperatures
3.5 Function
Liquid refrigerant is evaporated (evaporator). The en-
ergy for this process is ambient heat coming from the
outside air. The gaseous refrigerant is compressed
(compressor), which increases the pressure and thus
also the temperature. The gaseous refrigerant at high
temperature is liquefied (condenser).
In the process, the high temperature is transferred to
the heating water and used in the heating circuit. The
liquid refrigerant at high pressure and high tempera-
ture is expanded (expansion valve). The pressure and
temperature drop and the process restarts.
The heated heating water can be used for domestic hot
water or for heating the building. The temperatures re-
quired and the use are controlled by the heat pump con-
troller. Any required reheating, support in screed drying
or increase in the domestic hot water temperature can
be carried out using an electric heating element, which
is activated by the heat pump controller as required.
The vibration decoupling (accessory) for the hydraulic
system prevents structure-borne sound and vibrations
from being transferred to the fixed pipes and thus to the
building.
Cooling
The cooling function is only available on reversible
devices. The following options are possible for the
cooling function ( operating manual of the heating
and heat pump controller):
● Active cooling
Cooling down to a minimum flow temperature of
18 °C possible in combination with hydraulic mod-
ule or hydraulic station.
Cooling below 18 °C is only possible in the case
of hydraulic integration with separation buffer tank
● The cooling function is controlled via the heating
and heat pump controller
● Switching over between heating and cooling
mode
4 Operation and care
NOTE
The device is operated via the control panel
of the heating and heat pump controller
( Operation manual for the heating and
heat pump controller).
4.1 Energy and environmentally
aware operation
The generally applicable requirements for energy and
environmentally aware operation of a heating system
also apply to the use of a heat pump. The most impor-
tant measures include:
● No unnecessarily high flow temperature
● No unnecessarily high domestic hot water tem-
perature
● Do not open windows with a gap/in a tilted po-
sition (continuous ventilation), but instead open
them wide for a short time (shock ventilation).
● Always ensure that the controller setting is correct
4.2 Care
Wipe off the outside of the device only using a damp cloth
or cloth with mild cleaning agent (washing-up liquid,
neutral cleaning agent). Do not use any aggressive,
abrasive, acid or chlorine-based cleaning agents.
