All the more reason to control them remotely. The GENERAL AIRSTAGE UTY-TFSXJ4 \u003cstrong\u003eWi-Fi module\u003c\/strong\u003e connects these AIRSTAGE indoor units, GENERAL or Fujitsu, to the \u003cstrong\u003eAIRSTAGE Mobile\u003c\/strong\u003e app, so your \u003cstrong\u003eheating and cooling\u003c\/strong\u003e system can then be run from your phone. It is the same part as the Fujitsu AIRSTAGE module: Fujitsu General Limited has been called GENERAL Inc. since January 1, 2026.\u003c\/p\u003e\n\u003cp\u003eThe manufacturer, acquired by Paloma Rheem Holdings, has kept its factories, its AIRSTAGE products and its model numbers; the Fujitsu brand, meanwhile, is gradually stepping back behind GENERAL. During the transition, the part exists under both names, and AirGreen, an authorized GENERAL and Fujitsu AIRSTAGE dealer, lets you choose between this GENERAL model and \u003ca href=\"https:\/\/airgreen.ca\/products\/module-wi-fi-fujitsu-airstage-mobile-uty-tfsxj4-montreal-laval-longueuil-rive-sud-rive-nord\"\u003ethe same part under the Fujitsu AIRSTAGE brand\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eA Wi-Fi interface for ducted units, cassettes and consoles\u003c\/h2\u003e\n\u003cp\u003eThe USB module for wall-mounted units plugs in; the UTY-TFSXJ4, on the other hand, is a \u003cstrong\u003ewired interface\u003c\/strong\u003e. It connects to the indoor unit and draws its power from the unit's \u003cstrong\u003e12 V output\u003c\/strong\u003e, with no external power supply at all. It then joins the home's \u003cstrong\u003e2.4 GHz Wi-Fi\u003c\/strong\u003e network (IEEE 802.11b\/g\/n). Its housing stays compact: 3.75 x 1.5 x 0.56 in., for a weight of 0.1 lb.\u003c\/p\u003e\n\n\u003ch3\u003eMinimum heating, a feature made for our winters\u003c\/h3\u003e\n\u003cp\u003eOf all the features offered, \u003cstrong\u003eminimum heating\u003c\/strong\u003e is the one that owners of cottages, vacant rental units or businesses closed for the winter should look at closely. It holds a base temperature in an unoccupied building, enough to protect the plumbing and the finishes against the cold without paying for comfort nobody is enjoying. From the app, you see that the unit is running and you raise the setpoint before you arrive.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eweekly timer\u003c\/strong\u003e takes care of your schedules, and the \u003cstrong\u003eerror display\u003c\/strong\u003e warns you when the unit reports an anomaly: the service visit can then be planned without waiting. A single AIRSTAGE Mobile account can bring together \u003cstrong\u003eup to 50 indoor units\u003c\/strong\u003e, which is very useful in a rental building or a business with several zones. For \u003cstrong\u003evoice control\u003c\/strong\u003e, the module works with \u003cstrong\u003eAmazon Alexa\u003c\/strong\u003e and \u003cstrong\u003eGoogle Home\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eType\u003c\/strong\u003e: wired Wi-Fi interface intended for non-wall-mounted indoor units\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible systems\u003c\/strong\u003e: non-wall-mounted AIRSTAGE (GENERAL or Fujitsu) indoor units, such as slim ducts, compact cassettes and floor consoles; e.g. AUU7-18RLF compact cassettes and ARU7-24RLF slim ducts\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePower supply\u003c\/strong\u003e: 12 V output from the indoor unit, no external power supply\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWi-Fi\u003c\/strong\u003e: 2.4 GHz, IEEE 802.11b\/g\/n\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eApp\u003c\/strong\u003e: AIRSTAGE Mobile (iOS 15+, Android 8.0+)\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: weekly timer, minimum heating, error display\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCapacity of one account\u003c\/strong\u003e: up to 50 indoor units\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e: none\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDimensions and weight\u003c\/strong\u003e: 3.75 x 1.5 x 0.56 in.; 0.1 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility confirmed unit by unit\u003c\/h3\u003e\n\u003cp\u003eThis module was designed first for non-wall-mounted units. Some wall-mounted units from earlier generations may accept it too, but it all depends on each model's circuit board. That is why our technicians confirm the exact model number of each of your indoor units before ordering anything. For a recent \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e, the UTY-TFSXH4 USB module is generally the right choice.\u003c\/p\u003e\n\u003cp\u003eTake a house that combines a ducted unit upstairs and wall-mounted units on the ground floor: both types of modules can live in the same AIRSTAGE Mobile account. The whole house is then controlled from a single app, room by room or as a group, with a schedule of its own for each zone according to how it is used.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation by our technicians\u003c\/h2\u003e\n\u003cp\u003eThe module connects inside the unit. That means opening the unit's electrical panel, plugging into the right connector and mounting the module where the Wi-Fi signal is strong enough, which is not always a given in a ceiling or a basement. Our technicians take care of everything: they pair the module with the app, configure the weekly timer and, for a cottage or vacant premises, the minimum heating function. Every command is then tested from your phone.\u003c\/p\u003e\n\n\u003ch3\u003eMaintenance\u003c\/h3\u003e\n\u003cp\u003eNo maintenance is required for the module itself. All it takes is keeping the app up to date, and pairing the module again after a router change. On a ducted unit or a cassette, the priority remains maintenance of the filters and the drain, and the error display in the app helps you let nothing slip by.\u003c\/p\u003e\n\n\u003ch3\u003eAirGreen, your AIRSTAGE installer\u003c\/h3\u003e\n\u003cp\u003eHolding an RBQ licence, AirGreen Inc. is a family-owned air conditioning and heating company in business for more than 15 years, with a showroom in Boucherville.
