GENERAL PRODUCT DESCRIPTION

The instantaneous water heater DEX / DBX is a electronically controlled, pressure-resistant water heater for a

decentralised water supply to one or more tap connections.

Its electronic control regulates the power consumption depending on the selected outlet temperature, the

respective inlet temperature and the flow rate, thus reaching the set temperature exactly to the degree and

keeping it constant in case of pressure fluctuations.

For DEX the required outlet temperature can be entered on a keypad within the range 20 °C to 60 °C (DEX12

range is 20 °C to 55 °C) and can be read off the digital display.

For type DBX the factory set outlet temperature is 50°C and can be adjusted inside the appliance within the

range 30°C to 60°C.

For DEX (*excluding DEX12) a maximum inlet temperature of 70°C is suitable for use with preheated water

from solar heating systems.

*For DEX12 the maximum inlet temperature is 25°C.
