The new HRQ-4ZONE zoning system is a natural evolution of the HRQ-2ZONE zoning tee – an even more versatile response to the needs of modern, energy-efficient homes. It allows the home heat recovery system to be divided into four independent zones using two HRQ-4ZONE-Connection-Boxes, enabling control of up to eight air vents in different rooms. This provides greater flexibility in designing comfort – for example, it allows separate control of the air supply in the living room, study, bedroom, or children's rooms. When using a single HRQ-4ZONE-Connection-Box, the system can divide the installation into two zones, just like the classic HRQ-2ZONE.
