Highlights

Efficient energy saving

Compared to hydraulically controlled instantaneous water heater electronically controlled instantaneous water heater need 30 % less energy and water.

Childproof lock/scald protection

Pressing both temperature setting buttons simultaneously activates the childproof lock quickly and easily to prevent operation of the device. The childproof lock limits the

maximum temperature to 42°C, offering effective scald protection. The key symbol in the back-lit LCD indicates that the function is activated.

Back-lit LCD

Optimum display of settings and information.

"2-in-1" power switch

All devices bearing the "2-in-1" symbol provide a choice between two different performance levels during installation. Exclusive installers will enjoy a host of benefits as a result of this safe, easy-touse power switch: in the future, it will be possible to cover all market demand with a maximum of two appliance versions. As a result, it will no longer be necessary to support four performance versions, which will save storage and handling costs. The required power mode can be easily selected; the adjustment is made using the sliding switch on the controller.

CLICKFIX plus® — assembly has never been so quick

It really couldn't be quicker or easier: with the unique CLICKFIX plus® installation technology, our instantaneous water heaters are installed quickly, easily and accurately in three short steps. This not only makes new installations easy, but also simplifies the replacement of older devices.

Solar energy system

Electronically controlled instantaneous water heaters are perfect for heating up water from solar energy systems — up to 60°C, to the degree. This means that users of solar energy systems are independent from sun, wind and weather.

Shock/moisture protection to IP 25.

Water jet protection ensures easy installation, even in commercial applications.
