Frequently Asked Questions - DDLT PinControl 18 AEG

How to adjust the water temperature?

Use the power selector (position Partial power or Full power) and adjust the flow at the tap. For a higher temperature, close the tap slightly; for a lower temperature, open it more or add cold water.

Why is the appliance not heating?

First check the circuit breakers at the electrical panel. Then make sure the flow is sufficient (at least 3.0 l/min in setting I). If the jet regulator or shower head is scaled, clean it. If nothing works, contact an installer.

What to do in case of a power failure?

After a water cut, turn off the appliance, open the taps for one minute to purge air, then restore power. See the Settings chapter in the manual.

How to clean the appliance?

Use a damp cloth without abrasive or solvent. Regularly clean the taps with a commercial descaler. For the filter, close the cold water supply, disassemble it, clean it, and reassemble.

What is the maximum hot water flow rate?

The flow is limited to 5.9 l/min. At full power, you get approximately 9.2 l/min at 38 °C with 10 °C inlet water.

Can I use the appliance with preheated water?

No, using preheated water is not allowed. The maximum inlet temperature is 25 °C.

What is the minimum required water pressure?

The pressure must be sufficient to reach the switching flow rate (3.0 l/min in setting I). Generally, a pressure of 0.1 MPa (1 bar) is recommended for pipe sizing.

How to drain the appliance?

Close the shut-off valve, open all draw-off taps, then disconnect the hydraulic connections. Caution: water may be hot. Protect the appliance from frost after draining.

Is the appliance suitable for a shower?

Yes, by selecting full power, it can supply a shower. The flow can be adjusted for a comfortable temperature. Ensure the tap is suitable.

What does the indicator light or switching noise mean?

An audible click indicates that the differential pressure switch has activated the heating power. If the water does not heat despite the noise, the safety pressure switch may have cut the power: press the reset button after opening a tap for one minute.

3. Appliance description

The hydraulically controlled instantaneous water heater heats water as it flows through the appliance. When a tap is opened, the heating output starts automatically as soon as the start-up volume is exceeded (see chapter "Specification / Data table"). The water volume and temperature can be adjusted at the tap.

You can choose between 2 output stages. In addition, 2 output stages are hydraulically controlled in relation to the flow rate.

The flow rate controller compensates for pressure fluctuations, thereby ensuring largely stable temperatures. The controller limits the throughput, thereby ensuring an adequate increase in the DHW temperature at all times.

Heating system

The bare wire heating system has a pressure-tested plastic casing. The heating system is suitable for hard and soft water areas and is largely insusceptible to scale build-up. This system ensures rapid and efficient DHW availability.

4. Settings

Simple diagram of a circular object with a black bar and two dots, no text or symbols present.

26_02_02_0783

1 Partial load

At low throughput 1/3 of the heating output is activated; at higher throughput 2/3 of the available heating output is enabled. This setting is suitable for hand washing at a basin, for example.

2 Full load

At a low throughput, 50 % of the heating output is applied; at a higher throughput the full heating output is activated. This setting is suitable for washing dishes, for example.

» Click the output selector into the required position.

Recommended settings when using a thermostatic valve

» Set the output selector to full power.

4.1 Recommended tap/valve settings

Note
