WPL-A 13 HK 400 Premium

Application

• This air source heat pump with output-dependent control and inverter technology is installed outdoors. The compact mono block design is suitable for heating and DHW operation as well as for efficient cooling by means of circuit reversal. • The heat pump can be used for modernisation projects as flow temperatures of up to 65 °C are available for heating and DHW heating.

Convenience features

• Quiet operation thanks to the encapsulated refrigerant circuit and acoustically isolated compressor. Contributing to the low sound power level are the modulating fan and the wide gaps between the evaporator fins which reduce air resistance. • The combined enhanced vapour injection/enhanced saturated vapour injection cools the scroll compressor at low outside temperatures, which enables a higher heating output/flow temperature to be achieved. • When combined with the Internet Service Gateway, the integral heat pump manager allows the system to be controlled in the home network or from a mobile device. • With integral heat and electricity metering via refrigerant circuit data. • The electric emergency/auxiliary heater enables mono energetic operation. • The refrigerant circuit is hermetically sealed and checked for leaks at the factory. • The enamelled, corrosion-protected metal casing is made from hot-dip galvanised, powder coated sheet steel. Fan grille, recessed grips and cover are made from weatherproof and UV-resistant plastic.

Efficiency

• The refrigerant circuit works with the eco-friendly refrigerant R452B. • The waste heat from the inverter is used to raise the return temperature. In addition, the overall efficiency of the system is increased by on-demand defrosting through circuit reversal and heating of the condensate pan by the refrigerant circuit. • The hydrophilic coating on the fan nozzle prevents ice from forming, meaning that no electric heating is required.

Installation

• The integral anti-vibration mount enables the heat pump to be connected directly to the heating system. • The pivoting electrical connection panel makes installation easier. • The condensate pan can be easily reached through the cleaning aperture on the back of the casing.
