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 FE7 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

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 10m

and a pipe diameter of 22-28mm.

 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.

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 8-12weeks after commissioning and

during the annual system service.

Note

To prevent corrosion, desalinate water with conductivity >1000μS/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.
