4. Appliance description

The buffer cylinder and DHW cylinder with indirect coil are arranged one above the other and can be separated for easier handling.

The appliance has a plastic jacket with foam insulation and is equipped with a removable front casing. The appliance is connected hydraulically and electrically to the heat pump. All hydraulic connections are made at the top (heating) and rear (DHW).

In addition to the DHW cylinder and the buffer cylinder, further system components are integrated:

• Heat pump manager
• Highly efficient circulation pump for a heating circuit without mixer
• 3/2-way diverter valve
• Cylinder primary pump

DHW cylinder

The steel cylinder is coated on the inside with special direct enamel and is equipped with a signal anode. The anode with consumption indicator 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.

Buffer cylinder

The steel cylinder provides hydraulic separation between the flow rates of heat pump and heating circuit. The heating water heated by the heat pump is transferred into the buffer cylinder by the cylinder charging pump. When a demand is issued, the integral heating circuit pump delivers the heating water to the heating circuit.

Heat pump manager (WPM)

The system is controlled by means of the integral heat pump manager.

Note

The heat pump manager has an automatic summer/winter changeover so you can leave the system switched on in summer.

▶ Please observe the instructions for the heat pump manager.

5. Cleaning, care and maintenance

▶ Have the electrical safety of the appliance and the function of the safety assembly regularly checked by a qualified contractor.
▶ Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the unit.

10. Installation

10.1 Positioning the appliance

▶ When positioning the appliance, observe minimum clearances (see chapter "Preparations / Installation site").
▶ Use the adjustable feet to compensate for any unevenness in the floor.

10.2 Heating water connection

Material losses

The heating system to which the appliance is connected must be installed by a qualified contractor in accordance with the water installation drawings in the technical guides.

Material losses

When fitting additional shut-off valves, install a further safety valve in an accessible location on the heat generator itself or in the flow line in close proximity to the heat generator.

There must not be a shut-off valve between the heat generator and the safety valve.

Oxygen diffusion

Material losses

Do not use open vented heating systems. Use oxygen diffusion-proof pipes in underfloor heating systems with plastic pipework.

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 radiators or steel pipes).

▶ With heating systems that are permeable to oxygen, separate the heating system between the heating circuit and the buffer cylinder.

Material losses

The products of corrosion (e.g. rusty sludge) can settle in the heating system components, which may result in a lower output or fault shutdowns due to reduced cross-sections.

Supply lines

Note

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.

▶ Thoroughly flush the pipes before connecting the heat pump. Foreign bodies (e.g. welding pearls, rust, sand, sealing material, etc.) can impair the operational reliability of the system.

▶ Install the heating water pipes (see chapter "Specification / Dimensions and connections").
▶ Protect the flow and return lines against frost with sufficient thermal insulation.
▶ Connect the hydraulic connections with flat gaskets.

If the available external pressure difference is exceeded, 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.

We do not recommend desalinating the fill water, as this may cause a negative change in the pH value.

▶ If you desalinate the fill water or the pH value of the fill water is less than 8.2, check the pH value 8 to 12 weeks after installation, every time the system is topped up and the next time it is serviced.
▶ Do not add inhibitors or additives to the filling water.

Accessories for water softening

If you need to soften the fill water, you can use the following product.

• Heating water softener HZEA
• HZEN replacement cartridge
  ▶ Recheck these limits 8-12 weeks after commissioning, every time the system is topped up and during the annual service.

Appliance in low-occupancy buildings

During regular operation, the connection lines and the system are protected by the frost protection function of the appliance.

If the appliance is disconnected from the power supply for a longer period of time (shutdown, prolonged power failure), drain the appliance on the water side. Otherwise the appliance is not protected against frost.

If it is not possible to detect power failures (for example if the system is in a holiday home left vacant for extended periods of time), the following protective measure can be taken.

▶ Add a suitable concentration of ethylene glycol to the fill water (20-40 % by vol.). Observe the instructions for the antifreeze. Only use antifreeze products which have been approved by us.
▶ Please note that antifreeze changes the density and viscosity of the fill water.

To lock/unlock the buttons (press for 8 seconds)

Control modes and functions

Variable differential pressure p-v (I, II, III)

Recommended for two-pipe heating systems with radiators to reduce flow noise at thermostatic valves

The pump reduces the delivery head by half when the flow rate in the pipework decreases.

Saves energy by matching the delivery head to the flow rate demand and the lower flow velocities.

Choice of three pre-defined curves (I, II, III).

Constant pressure differential p-c (I, II, III)

Recommended for underfloor heating systems, large pipework or any application with a non-varying pipework curve (e.g. cylinder charging pumps), as well as single-pipe heating systems with radiators

The control system keeps the set delivery head constant, irrespective of delivered flow rate.

Choice of three pre-defined curves (I, II, III).

Constant speed (I, II, III)

Recommended for systems with unchanging system resistance which require a constant throughput.

The pump runs at three preset fixed speed levels (I, II, III).

Note

Factory setting: Constant speed, curve III

Venting

Filling and venting the system correctly

If the pump does not vent automatically:

Activate the venting function via the operating button,

press button for 3 seconds, then release it.

Venting function starts (duration 10 minutes).

The top and bottom rows of LEDs flash alternately every second.

To cancel, press the operating button for 3 seconds.

Note

After venting, the LED indicator displays the previously set pump values.

Setting control modes

Selecting the control mode

The LEDs for the control modes and associated curves illuminate one after the other.

Briefly press the operating button (for approx. 1 second).
