Application

• This fully electronically controlled comfort instantaneous water heater with 4i technology guarantees accurate temperature delivery thanks to electronic flow rate control. • The unvented, pressure-tested appliance supplies DHW conveniently and energy efficiently to multiple draw-off points, for example the bathroom and the kitchen. • The instantaneous water heater can be combined with all commercially available pressure taps. • Highly convenient undersink installation since the appliance cover and the programming unit can be turned the other way up.

Convenience features

• Energy saving 4i technology with three sensors and an additional motorised valve ensures that the set temperature is achieved to the exact degree at all times. • The Touch-Display and a Touch-Wheel enable variable temperature selection. In addition, there are twelve customisable memory buttons. The wellness shower programs, automated bath filling function and several timer programs all contribute towards increased comfort. • The maximum temperature limit can be set to suit individual requirements. An LED indicator warns of scalding if the outlet temperature increases unexpectedly due to preheated water from solar thermal systems or heat pumps. • The appliance can access internet radio stations and online weather data via the user's WLAN. The loudspeakers required for this are built into the instantaneous water heater. External speakers can also be connected, and music streamed via the Bluetooth interface. • A mini wireless remote control is included.

Efficiency

• The instantaneous water heater ensures energy and water savings of up to 30 % through fully electronic output control via 4i technology. There is no need to add cold water at the tap, which additionally enhances the efficiency of the appliance, as does the individually selectable ECO mode. • The consumption indicator ensures significantly better cost transparency.

Installation

• Very quick installation using the improved PROFI-RAPID installation system. Easy replacement of all standard instantaneous water heaters. Any wall unevenness and drill hole discrepancies are compensated for by the universal mounting rail which is also suitable for commonly used fixing points. • Fast, universal water connection thanks to the enlarged installation area with pivoting cold water inlet. Threaded water connections and twin nipple connections also contribute to easy replacement. • Either surface-mounted or flush-mounted installation is possible. • Suitable for plastic pipes (observe manufacturer's instructions). • Easy mains connection, either from above or below. A cable insertion aid is incorporated. • The guided installation process ensures commissioning is quick.

Safety

• The quick-action bare wire heating system is suitable for hard and soft water. • The electronic multi stage safety concept detects air bubbles in the system and automatically deactivates the appliance if the temperature is too high.

Application • These very compact small water heaters with their attractive design are suitable for supplying hot water to individual draw-off points, for example a bathroom washbasin or a kitchen sink. • The non-pressurised appliances provide DHW with no waiting time. • Operation with non-pressurised taps only.

Convenience features • The very small casing is distinguished by its surface structure that feels pleasant to the touch. • Variable temperature adjustment is possible using the high quality haptic rotary selector. • Limescale deposits and water consumption are reduced thanks to the anti-drip function on the 5 litre undersink appliance. This prevents expansion water dripping during heat-up. • Fast and accurate temperature capture as the sensor is immersed directly in the water. • 4-stage temperature limit. • Automatic frost protection setting when the appliance is off. • A visual display indicates when the small water heater is heating up.

Efficiency • Low energy losses thanks to high grade EPS thermal insulation of the polypropylene inner cylinder. • The energy saving thermostop function prevents unwanted heating of the tap. • Very low standby energy consumption.

Installation • Quick installation with the Profi-Rapid installation system. The small water heater is suitable for commonly used fixing points, so that existing appliances can be quickly replaced. • Straightforward wall mounting thanks to universal mounting rail. • Safety due to metal threaded water fittings. • Choice of power cable: permanent connection or with standard plug. Any excess cable is housed in the cable storage compartment in the appliance back panel. • Splashproof.

Safety • The robust copper tubular heater ensures a long service life. • Safe commissioning thanks to resettable temperature limiter. • The integral anti-scalding protection can be set using the mechanical temperature limit. • The rotary selector is simply removed for the DGUV V3 test, so the test point is always accessible.

Application • This output-controlled integral system with reversible air source heat pump performs the following tasks in new builds and detached houses: central ventilation, central DHW heating, heating and cooling.

Convenience features • The integral electronic weather-compensated control unit ensures output control for all application areas. The intelligent controller allows program preselection for fans, heating, DHW and absence or holidays. • A range of additional functions is also available: humidity protection ventilation with integral humidity sensor in the extract air, air flow rate reduction when humidity is too low, passive cooling and screed drying program. • The programming unit is integrated directly in the appliance, with the option of adding a remote control with humidity sensor. • Extensions in the form of the Internet Service Gateway with optional KNX and photovoltaic optimisation are available as add-ons. • Extensive safety equipment in the refrigerant circuit of the air source heat pump. • Cooling with option of direct area cooling. • An electric emergency/auxiliary heater for DHW heating and room heating is built in. • The specially enamelled DHW cylinder has a protective anode with electronic monitoring. • Outdoor air is preheated by a refrigerant circuit supercooler. • Coarse dust filters are integrated for the supply and extract air.

Efficiency • High efficiency due to demand-dependent control of the inverter compressor. • To be able to use solar thermal energy, an additional solar heat exchanger is integrated into the heating circuit. • The combination of the plastic cross-countercurrent heat exchanger and the economical constant flow rate fan is particularly efficient.

Installation • All air connections are located at the top of the appliance. • The robust sheet steel casing has a contemporary design.

Application • This compact ground source heat pump with output-dependent control, inverter technology and integral DHW cylinder is installed indoors. The high level of integration facilitates installation. Does not take up much space thanks to the small footprint. • The heat pump can be used for modernisation projects as flow temperatures of up to 75 °C are available all year round for room heating and DHW heating. • An intermediate heat exchanger is incorporated for energy efficient passive cooling via the underfloor heating system. • Mono mode is possible for both heating and DHW heating. 

Convenience features • Very quiet operation is ensured by the encapsulated refrigerant circuit and acoustically isolated compressor. • The heat pump offers demand-dependent fully automatic control. • If the integral heat pump manager is connected to the Internet Service Gateway, the system can be integrated into a smart home network and controlled via a mobile device. • With integral heat and electricity metering via refrigerant circuit data. • One high efficiency circulation pump is built in for the brine side and one for the heating side. • Electric emergency/auxiliary heater for mono energetic operation and pasteurisation. • Diverter valve for DHW heating and safety valve with drain pipe. • The refrigerant circuit works with the eco-friendly, futureproof refrigerant R454C, which has excellent properties in heat pump application. • The corrosion-protected casing is made from hot-dip galvanised, powder coated sheet steel.

Efficiency • Thanks to the energy saving inverter technology and integral recuperator, the heat pump works efficiently all year round.

Installation • No special safety precautions are required when siting. A minimum room size must be ensured. • To facilitate installation, the refrigerant circuit can be easily separated from the cylinder module. Both parts have integral carrying handles. • The supplied pressure hoses enable direct hydraulic connection to the heating side and source side.
