01Overview
All-in-One Home Air Comfort Unit
SPARROW is an all-in-one climate unit that combines heating, cooling and fresh air supply in a single compact appliance. The incoming fresh air recovers the energy of the exhaust air in a counter-flow heat exchanger with a temperature efficiency above 75%. The space is thus supplied continuously with fresh air while most of the heating and cooling energy is retained.
The inverter scroll compressor adjusts capacity to instantaneous demand, and variable-speed EC plug fans ensure low energy consumption and quiet operation. Heating is not interrupted during defrost, and no defrost is required at outdoor temperatures above 3 °C. The unit operates at outdoor temperatures from −10 °C to 45 °C.
The range comprises three models, SPARROW 300, 500 and 700, and is suitable for residential buildings as well as non-industrial spaces such as offices, medical practices and retail premises. All models feature ISO 16890 ePM10 75% filters, a dirty-filter alarm, Modbus / BACnet support and a built-in web interface.
Summer and winter operation
- 01
Heat-recovery ventilation
A counter-flow exchanger with a temperature efficiency above 75% transfers energy from the exhaust air to the fresh air.
- 02
Inverter compressor and EC plug fans
An inverter scroll compressor and variable-speed EC plug fans ensure that the unit operates only at the capacity required.
- 03
Continuous heating
Heating continues during defrost; no defrost is required at outdoor temperatures above 3 °C.

The 3D model is about 3.2 MB; loading may take a few seconds depending on your connection.
03Technologies
Key technologies.
- 01
Inverter scroll compressor
A variable-speed compressor that modulates capacity to demand without on/off cycling.
- 02
EC plug fans
Belt-free, direct-drive brushless design with speed control from 20% to 100%.
- 03
Counter-flow heat recovery
With a temperature efficiency above 75%, the exchanger retains most of the energy that would otherwise be lost.
- 04
Electronic expansion valve
Precise refrigerant feed under all operating conditions, controlled by a superheat algorithm.
- 05
Home and building automation
Modbus RTU, Modbus TCP/IP, BACnet MS/TP, BACnet TCP/IP and a built-in web interface; smart home integration is optional.
04Applications
Typical applications.
Homes and offices
