Your new device

The hot water storage units DG80025 – DG15025 with electronic control are designed for the heating of drinking water accord-

ing to DIN 1988.

They can provide hot water to 85°C and, depending on the mode of operation, service one or more taps (tapping points). The

water is heated electrically. On the control panel the current amount of available hot water is displayed by 6 LEDs. The hot

water storage units are equipped with an active, electronic corrosion protector (external power source anode).

Control Panel

Service and Operation

The hot water temperature may be set between * and 85°C using the dial. We recommend the setting of 60°C. Heat

wastage and calcification are lowest here.

Upon reaching the set temperature all 6 thermal capacity indicators LEDs light up. As hot water is extracted the amount of hot

water available in the reservoir decreases. The less hot water available, the fewer LEDs are lit up.

The heating period is dependent upon the volume of water in the reservoir, the cold water intake temperature, and the set heat

output.

See technical data table (page 15)

The hot water storage unit may be used optionally for

closed (pressurised) operation

suitable for service of multiple tapping points

open (de-pressurised) operation

suitable for service of one tapping point

There are three variations of electrical connections to choose from:

Single-power operation

Reheating occurs automatically subject to the power supply.

The button “fast-heating” is only used for the reset and diagnostic routine functions (technician).

Double-power operation

During off-peak periods, the hot water storage unit automatically heats the

contents of the reservoir at the configured basic performance. The quick heating may be activated by pressing the

fast-heating button . As the device is heating up the LED lights up, before going out again as soon as the

set temperature is reached. The 'fast-heating' switches itself off automatically.

Boiler mode operation

In this mode the hot water storage unit heats the contents of the reservoir once upon the initial operation at the con-

nected and configured basic performance. Each further heating procedure must be started manually by pressing the

button fast-heating .
