SPECIAL INFORMATION
- The appliance may be used by children aged 8
and older and persons with reduced physical,
sensory or mental capabilities or a lack of experience and know-how, provided that they are
supervised or they have been instructed on how
to use the appliance safely and have understood
the resulting risks. Children must never play with
the appliance. Children must never clean the appliance or perform user maintenance unless they
are supervised.
- The connection to the power supply must be in
the form of a permanent connection. Ensure the
appliance can be separated from the power supply by an isolator that disconnects all poles with
at least 3mm contact separation.
- Maintain the minimum clearances in order to ensure trouble-free operation and to allow enough
space for maintenance work on the appliance.
- Maintenance work, such as checking the electrical safety, must only be carried out by a qualified
contractor.
- We recommend an annual inspection (to establish
the system's current condition), and maintenance
by a qualified contractor if required (to return the
system to the intended condition).
- Never interrupt the power supply, even outside
the heating season. The system's active frost protection is not guaranteed if the power supply is
interrupted.
- Size the drain pipe so that water can drain off unimpeded when the safety valve is fully opened.

OPERATION
Appliance description
4. Appliance description
The appliance is a hydraulic module with an integral DHW cylinder.
The appliance is designed for indoor installation. The appliance is
connected hydraulically and electrically to the heat pump.
The appliance transfers the heat absorbed by the heat pump to
the heating system and the domestic hot water. During this process, DHW is heated to the required temperature via an internal
indirect coil.
Note
The appliance can be used with a heat pump with cooling
capability.
A multi-function assembly (MFG) with safety assembly and 3-way
diverter valve is integrated into the appliance. The MFG is used for
switching between the heating circuit and the DHW circuit. 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 also regulates the DHW heating
to the required temperature.
Further features
- Robust metal casing made from galvanised, powder-coated
and stove enamelled sheet steel
- Integral diaphragm expansion vessel for the heating circuit
- High levels of DHW convenience thanks to an enamelled DHW
cylinder with internal indirect coil
- Switching to DHW heating via a diverter valve
- Pasteurisation function
- Adjustable heat-up program for drying a screed with an underfloor heating system
- Hours run meter for the connected heat pump
Control unit
The system is controlled by means of the integral heat pump manager.
The heat manager is suitable for the control of a direct heating
circuit and a heating circuit with mixer.
A seven-day heating program is integrated in the heat pump manager which you can use to set the times and temperatures for
central heating and DHW heating.
You can extend the heat pump manager with the following components:
- Room temperature controllers FE7 and FEK for controlling
the direct heating circuit and the heating circuit with mixer.
- Mixer module MSM, if connecting a second heating circuit
with mixer
5. Settings
The system is controlled by means of the integral heat pump manager.
Please observe the heat pump manager operating and instal-
lation instructions.
6. Cleaning, care and maintenance
Material losses

INSTALLATION
Installation
Provide thermal insulation in accordance with applicable
regulations.
Oxygen diffusion
Material losses
!
Avoid open heating systems and plastic pipes in underfloor heating systems which are permeable to oxygen.
In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen
diffusion may lead to corrosion on the steel components of the
heating system (e.g. on the indirect coil of the DHW cylinder, on
buffer cylinders, steel heating elements or steel pipes).
Material losses
!
The products of corrosion (e.g. rusty sludge) can settle in
the heating system components and can result in a lower
output or fault shutdowns due to reduced cross-sections.
Supply lines
The maximum permissible line length between the appliance and
the heat pump will vary, depending on the version of the heating
system (pressure drop).
As a standard value, assume a maximum line length of 10m
and a pipe diameter of 22-28mm.
Protect the flow and return lines against frost with sufficient
thermal insulation.
Provide thermal insulation in accordance with applicable
regulations.
Only use weather-resistant cables.
Also protect all supply lines/cables against humidity, damage
and UV radiation by means of a conduit.
Sample installation

11.4 Connection to the heat pump
The appliance and the heat pump are connected to one another hydraulically via pipes carrying heating water. To reduce the
transmission of structure-borne noise on the water side, connect
the appliance to the heat pump with pressure hoses (not required
for WPL 15-25 A).
When sizing the pipes, take the following information into
account:
Available pressure differential
If you exceed the permissible value, the pressure drop in the heating system could result in a reduced heating output.
When sizing the pipes, ensure that the available external
pressure differential is not exceeded (see chapter "Specification/ Data table").
When calculating the pressure drop, take account of the flow
and return lines and the pressure drop of the heat pump.
The pressure drop must be covered by the available pressure
differential.
11.5 Filling the system
Water quality
Carry out a fill water analysis before the system is filled. This
analysis may, for example, be requested from the relevant water
supply utility.
To avoid damage as a result of scaling, it may be necessary to
soften or desalinate the fill water. Always observe the fill water
limits specified in chapter "Specification / Data table".
Recheck these limits 8-12weeks after commissioning and
during the annual system service.
Note
To prevent corrosion, desalinate water with conductivity
>1000μS/cm before use.
Note
If you treat the fill water with inhibitors or additives, the
same limits as for desalination apply.
Note
Suitable appliances for water softening, as well as for
filling and flushing heating systems, can be obtained from
trade suppliers.
