LWZ 8 CS Premium

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.
