Intended use
The appliance is used for heating and seasonal cooling of rooms
and for DHW heating. For sub dew point cooling, CDT 180 conden-
sate pump and condensate pan accessories must be used. With
the CDT 180 accessories, cooling rooms is only permissible with
monitoring of the dew point. Sub dew point cooling is only ever
permissible on a seasonal basis with a subsequent heating period.
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-do-
mestic environments, e.g. in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappro-
priate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this
appliance.

with the appliance. Cleaning and user maintenance must
not be carried out by children without supervision.
WARNING Injury
!
For safety reasons, only operate the appliance with the
front casing closed.
Note
The DHW cylinder is under supply pressure. If no dia-
phragm expansion vessel is installed, expansion water
will drip from the safety valve during heat-up.
f If water continues to drip when heating is complet-
ed, please inform your qualified contractor.

Appliance description
The appliance comprises a hydraulic module and an integral DHW
cylinder and is equipped with a removable front casing. The appli-
ance is connected hydraulically and electrically to the heat pump.
In addition to the DHW cylinder, the following system components
are integrated:
- Heat pump manager
- Cylinder charging pump / heating circuit pump
- Multifunction assembly with safety valve, 3-way diverter
valve and emergency/booster heater for mono energetic
operation
DHW cylinder
The steel cylinder is equipped with special directly applied enamel
coating on the inside and a sacrificial anode. The sacrificial anode
protects the cylinder interior from corrosion.
The heating water heated by the heat pump is pumped through an
indirect coil inside the DHW cylinder. The heat channelled through
the indirect coil is thus transferred to the domestic hot water. The
integral heat pump manager regulates the DHW heating to the
required temperature.
Heat pump manager (WPM)
The system is controlled by means of the integral heat pump man-
ager.
The heat pump manager is suitable for the control of a direct
heating circuit and a heating circuit with mixer.
You can set the times and temperatures for heating operation and
heating DHW. Remote controls for controlling the heating circuit
are available as accessories.
For detailed information, see the enclosed operating and instal-
lation instructions for the WPM heat pump manager.
Multifunction assembly (MFG)
3-way diverter valve: The multifunction assembly switches be-
tween heating circuit and DHW heating.
Safety valve: When the pressure is high, the safety valve opens to
relieve the pressure in the system.
Air vent valve: Components are vented through air vent valves,
e.g. pipes or indirect coil.
