LWZ 5 S Trend
Product detailsAPPLICATION: Integral system with output-dependent control, featuring an air | water heat pump for central ventilation and heating, combined with external DHW cylinder in new builds and detached houses.
EQUIPMENT/CONVENIENCE: Integral electronic weather-compensated control unit to regulate the heating output, DHW output 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 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. Electric emergency heater for heating and DHW heating. Possible to combine with external cylinders of various sizes. Highly efficient cross-countercurrent heat exchanger made from plastic with economical, constant flow rate fan. Outdoor air is preheated by a refrigerant circuit supercooler.
EFFICIENCY: High efficiency thanks to optimised refrigerant circuit; energy efficient due 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. Easy access to electrical connection panel.
