  • Control Options for Hybrid Flex Inverter (HFI) Systems

    I have a Fujitsu multizone system. The outdoor unit is AOU36RLXFZH and the indoor units are ARU9RLF, ARU12RLF, and ARU18RLF. I would like a Central Remote controller to see all three units together and have the low noise option. Wi-Fi capability will also be a great aspect. Is there a way that this can be put together?

    Below are solutions that you may consider with respect to central control of your indoor units:

    1. Wireless LAN Adapter

    This option uses 3 WLAN adapters (UTY-TFNXZ2) for each indoor unit (each indoor unit requires its own interface module/ WLAN Adapter). The UTY-TFNXZ2 WLAN adapter / WIFI Interface Module provides remote cloud control and monitoring of your slim duct system through the internet using the free FGLair App (Smartphone). For initial setup, the smartphone has to be connected to the same wireless router that the WLAN adapter is connected.

    2. Wired Central Controller

    This option uses the UTY-DMMUM Central remote controller (wired) that allows control of up to 8 indoor units on a Hybrid Flex Inverter (HFI) system (in your case AOU36RLXFZH) which can be done simultaneously. The Remote controller connects in daisy chain to branch boxes.
