It is identical to the module sold under the Fujitsu AIRSTAGE name, since Fujitsu General Limited adopted the name GENERAL Inc. on January 1, 2026 without changing its range. Designed for \u003cstrong\u003eAIRSTAGE (GENERAL or Fujitsu) wall-mounted heat pumps\u003c\/strong\u003e, it plugs into the indoor unit's \u003cstrong\u003eUSB port\u003c\/strong\u003e and links the unit to the \u003cstrong\u003eAIRSTAGE Mobile\u003c\/strong\u003e app on your phone.\u003c\/p\u003e\n\u003cp\u003eSame manufacturer, same factories, same model numbers: only the name has changed, following the company's acquisition by Paloma Rheem Holdings. Until the Fujitsu brand has fully given way to GENERAL, both versions of the module will sit side by side on the market.

The indoor unit powers it directly, and it joins the home's \u003cstrong\u003e2.4 GHz Wi-Fi\u003c\/strong\u003e network (IEEE 802.11b\/g\/n, channels 1 to 11 in Canada). In the app, you find everything the remote does: on and off, mode, temperature, fan speed and airflow direction, with the one difference that you can do it from anywhere.\u003c\/p\u003e\n\u003cp\u003eThe app is also used to build \u003cstrong\u003eweekly schedules and timers\u003c\/strong\u003e, check the \u003cstrong\u003eindoor and outdoor temperature\u003c\/strong\u003e, control \u003cstrong\u003eseveral units as a group\u003c\/strong\u003e and grant \u003cstrong\u003eaccess levels\u003c\/strong\u003e to family members or staff.

You need \u003cstrong\u003eone per indoor unit\u003c\/strong\u003e: a house with three wall-mounted heads will need three modules. For a ducted unit, a cassette or a floor console, the manufacturer offers a different module, the UTY-TFSXJ4. As for the AIRSTAGE Mobile app, it runs on phones with iOS 15 or later and Android 8.0 or later; it does not support tablets.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eType\u003c\/strong\u003e: Wi-Fi interface module that plugs into the USB port\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible systems\u003c\/strong\u003e: AIRSTAGE (GENERAL or Fujitsu) wall-mounted indoor units in the ASUG, ASUH and ASLH series, e.g. ASUH09LMAS, ASUH24LPAS, ASUH36KPAS\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eQuantity required\u003c\/strong\u003e: one module per indoor unit\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePower supply\u003c\/strong\u003e: via the indoor unit's USB port\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWi-Fi\u003c\/strong\u003e: 2.4 GHz, IEEE 802.11b\/g\/n, channels 1 to 11\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eApp\u003c\/strong\u003e: AIRSTAGE Mobile (iOS 15+, Android 8.0+; no tablet support)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eVoice control\u003c\/strong\u003e: Amazon Alexa, Google Home\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFunctions\u003c\/strong\u003e: on\/off, mode, temperature, ventilation, airflow direction, weekly schedules, timers, indoor and outdoor temperatures, group control, access levels\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eUpdates\u003c\/strong\u003e: firmware updated over the Internet\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eGateway\u003c\/strong\u003e: none needed\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e: none\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSavings and peace of mind all winter\u003c\/h3\u003e\n\u003cp\u003eOn a \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e, weekly schedules let you lower the setpoint a little at night or during working hours, then return to comfort at the time you choose. At a secondary residence, remote control avoids heating full blast all week: you keep a moderate temperature and raise the setpoint a few hours before arriving. Seeing the outdoor temperature in the app also helps you understand how the unit behaves when the mercury plunges.\u003c\/p\u003e\n\u003cp\u003eAccess levels come in handy in a duplex, an intergenerational home or a small business: the owner keeps all the settings, and the other users only have the everyday functions. Thanks to group control, every wall-mounted unit in the house adjusts in one move: handy, for example, to lower the setpoint everywhere before leaving on vacation.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation and pairing, done by AirGreen\u003c\/h2\u003e\n\u003cp\u003eOur technicians first make sure that your wall-mounted unit is one of the compatible models. They then plug the module into the USB port and measure the Wi-Fi signal strength where the indoor unit sits, because a weak signal near an exterior wall or in the basement is common. Next, they pair the module with AIRSTAGE Mobile and create your first schedules with you. On request, we also set up access for the other members of the household and the link with Alexa or Google Home.\u003c\/p\u003e\n\n\u003ch3\u003eMaintenance\u003c\/h3\u003e\n\u003cp\u003eAs for the module, it needs no maintenance at all. A new router or a new Wi-Fi password only means redoing the pairing in the app. What remains essential is regular cleaning of the wall-mounted unit's filters, for performance as well as for air quality.\u003c\/p\u003e\n\n\u003ch3\u003eWhy AirGreen\u003c\/h3\u003e\n\u003cp\u003eMore than 15 years of experience, an RBQ licence and a showroom in Boucherville: AirGreen Inc. is a family-owned air conditioning and heating company. Throughout the greater Montreal area, we install AIRSTAGE \u003cstrong\u003ewall-mounted heat pumps\u003c\/strong\u003e along with the accessories used to control them.
