3.2 Functions

Using bare wire heating in the unit's heating block, drinking water is heated and can then be drawn from one or more points. The electronics measure the temperature of the cold water supply and the water volume flow. The electrical performance required to heat the water to the required temperature is calculated using these two values. The unit's display temperature can be changed in increments of 0.5 °C. The volume and heat of the hot water is dependent on the electronicVED exclusive performance category and settings. The output of each VED unit is listed in section 11. In addition, the water and energy consumption data can be linked to the performance data via the display. This means that the electronicVED exclusive can be configured in such a way that both the current and cumulative energy consumption can be displayed and called up. The built-in "Memo" function allows four fixed temperatures to be saved and these can be called up by pressing a button or by remote control.

Danger!

Risk of death from electric shock due to water penetration if the anti-spray-water sleeve is completely cut away.

The anti-spray-water sleeve should prevent water penetrating the unit along the length of the mains connection cable. If the antispray-water sleeve is completely cut away, water can very easily penetrate and damage the unit and, in the worst case scenario, can cause a potentially lethal electric shock.

> Never cut off the anti-spray-water sleeve

completely.

> Cut the end of the anti-spray-water

sleeve in such a way that the sleeve tightly surrounds the mains connection cable.

Detecting and rectifying faults

8 Detecting and rectifying faults

The faults listed here must only be rectified by an approved heating specialist company. When rectifying faults, note the following:

> Only use genuine spare parts for repairs. > Make sure the parts are correctly fitted and that their

original position and alignment are retained. > When removing water-carrying parts, capture the resid-

ual water (up to 0.4 litres) left inside the unit using a

suitable container.

When diagnosing and rectifying faults, always

follow the order stated in Table 8.1 for each indi-

Ensure that the unit is supplied with the L1, L2 and L3 mains voltage. Check the protective devices. De-energise the unit and open the unit cladding. Check all the connection line connectors.

Undo the connections 1 and 4 from the electronics. Measure the resistance value on the lines between the connections 1 and 4. The resistance must be < 200 ohm.

Ensure that there is an adequate water flow rate of more than 3 l/min. If the water volume is too low, check the water pressure, the fittings and the filter in the inlet. If the required water volume is not reached, check the motorised valve.

No switch (click) can be heard:

De-energise the unit and remove the unit cladding.· Check that the impeller moves freely by blowing hard on the inlet side; if necessary, clean or replace the impeller.· Otherwise, replace the electronics.

Switch (click) can be heard:

Check that the water temperature reaches the target temperature.

Fluctuation in the outlet temperature:·

Replace the electronics. Water temperature is not reached:·

- Water feels too cold even though the outlet temperature displayed corresponds to the target value. Check the external sensor and replace it if necessary.

- The water volume displayed is lower than the actual water volume. The impeller is probably not turning correctly. Check the impeller for blockages. Check the motorised valve as described in point 6.· If the motorised valve functions correctly, change the electronics.

unit cladding is closed. De-energise the unit for approx. 10 seconds. Switch the mains voltage on again. A motor noise must immediately be audible (the motorised valve is starting up). If you do not hear a motor noise, the valve is defective and must be replaced. If the motorised valve is working perfectly again, set the temperature to 60 °C. Quickly open a draw-off point with the highest flow rate possible (e.g. a bath). Then slowly reduce the flow rate and measure whether the selected outlet temperature is reached.

Inspection and maintenance89

8.1 Possible problems when using the remote control

Problem-free operation of the radio remote control for the electronicVED exclusive is dependent on the environmental conditions at the place of use. For example, the transmission of the radio signals may be impeded. Causes for this include objects in the path of the radio waves, e.g. walls, ceilings or other objects which can block radio waves. Other radio-transmission installations (e. g. weather stations) can also disrupt communication between the remote control and the electronicVED exclusive.

> If the operator is experiencing problems when using the

radio remote control, refer them to the information provided above.

> If the operator is experiencing problems when using the

remote control, first refer them to the following general points:

– The batteries must provide sufficient power. – The remote control must not be too far away from the

electronicVED exclusive.

– A functional and visual inspection of the unit must be

carried out every three years by a competent person.

– If the water is very hard, more regular de-scaling may be

necessary.

– If the water has a large volume of suspended matter, the

water filter in the cold water flow must be replaced more often. At the same time, the water filter has a sealing function.

Carry out the following actions:

> Replace the water filter in the cold water flow. > Check for deposits in the hot water pipe between the

heating block and the hot water connection.

> When re-assembling the unit, insert a new flat seal into

the hot water connection.

> Check whether the unit needs to be de-scaled and do so

if required.

live lines and connections!

> Isolate all electrical supplies and connec-

tions from the power supply before carrying out maintenance or repair work.

> Check that there is no voltage in the sup-

ply lines and connections.

> Ensure that the voltage cannot be inad-

vertently restored to any of the supply lines and connections while you are working on the unit.

If the unit needs to be completely de-scaled,
