LWZ 8 CS Premium
- Compact appliance offering the following functions: ventilation, central heating, DHW heating and cooling
- Matrix display with „Touch Wheel“ for intuitive operation
- Integral high efficiency pump for energy saving heat distribution
- Integral DHW cylinder for maximum DHW convenience
- Ergonomically designed programming unit for easy operation
EQUIPMENT/CONVENIENCE: Integral electronic weather-compensated control unit for output-dependent control of the heating output, DHW output, solar thermal system, cooling and ventilation. Intelligent control unit with preselected programs for fans, heating, DHW and absence/holiday. Additional functions such as humidity protection ventilation with integral humidity sensor in the extract air, air flow rate reduction when humidity is too low, passive cooling and dry heating program. Integral programming unit, remote control unit with humidity sensor optional. Internet Service Gateway (ISG) with optional KNX and PV optimisation. The refrigerant circuit of the air | water heat pump is equipped with all necessary safety equipment. Output-controlled cooling with option of direct area cooling. Electric emergency/booster heater for heating and DHW heating. The integral DHW cylinder has a special enamel coating and is equipped with a protective magnesium anode with electronic monitoring. Highly efficient cross-countercurrent heat exchanger made from plastic with economical, constant flow rate fan. Outdoor air is preheated by a refrigerant circuit supercooler. Additional solar heat exchanger in the heating circuit for utilising solar thermal energy.
EFFICIENCY: High efficiency thanks to demand-dependent control of the inverter compressor. Energy efficient thanks to constant flow rate fan.
INSTALLATION: The outdoor air, supply air, exhaust air and extract air connections are located at the top of the appliance. Robust sheet steel casing in a modern, award-winning design.
