Fujitsu Hybrid Flex Inverter systems are a perfect blend of complex VRF systems and simple Multi-zone systems. It is an ideal setup for homes and businesses where multi-zone outdoor units can operate from 2 to 8 indoor units simultaneously.
Some advantages of HFI systems include:
- Lower copper tubing costs
- Easier installation
- SEER rating
- Up to 8 zones can be controlled
- 80 to 130% connectable capacity
- Long piping
You can be able to create several indoor unit combination styles for wall-mounted, slim ducts, floor mounts, and compact cassettes systems.
Wall mounted: ASU7RLF1, ASU9RLF1, ASU12RLF1, ASU9RLS2, ASU12RLS2, ASU15RLS2, ASU18RLF, ASU24RLF
Slim ducts: ARU7RLF, ARU9RLF, ARU12RLF, ARU18RLF, ARU24RLF
Floor mounts: AGU9RLF, AGU12RLF, AGU15RLF
Compact cassettes: AUU7RLF, AUU9RLF, AUU12RLF, AUU18RLF
Control of these systems can be done centrally or individually as discussed below.
Wired Central Controller
It utilizes the UTY-DMMUM
Central remote controller (wired) that allows simultaneous control of up to 8 indoor units on a Hybrid Flex Inverter (HFI) system. The Remote controller connects in a daisy chain to branch boxes.
Wireless Interface adapters
This option uses Fujitsu wireless adapters/modules
for each indoor unit. It provides remote cloud control and monitoring of your slim duct system through the internet using the free FGLair App (Smartphone). For the initial setup, the smartphone/device has to be connected to the same wireless router that the adapter is connected to.
See the illustration in the below schematic diagram:
