Does my wall unit need a kit for a wired controller?

Yes. The Altair 500 and Orion XLTH need the UTY-TWRXZ2 communication kit. For the Orion XLTH+, Fujitsu’s spec sheet lists the UTY-TWRXZ4; we confirm from your model number.

Can I keep my Nest or Honeywell thermostat?

Yes, with the UTY-TTRXZ1 24 V interface. It must be the only control, though: no remote, Wi-Fi adapter or building system at the same time.

Does my unit have built-in Wi-Fi?

The Orion XLTH and Orion XLTH+ wall units do. The Altair 500 uses the UTY-TFSXH4 USB adapter. Cassettes, ducted units and air handlers use the UTY-TFSXJ4.

AIRSTAGE Mobile or FGLair: which app?

Check your adapter’s Wi-Fi network name. If it starts with AP-WH or AP-WJ and ends with E, it’s AIRSTAGE Mobile. Otherwise, it’s FGLair.

Can I control the heat pump by voice?

Yes. FGLair and AIRSTAGE Mobile both work with Amazon Alexa and Google Assistant.

How many people can control the unit in the app?

Up to five accounts per indoor unit in AIRSTAGE Mobile, including the main user.

How many units can one wall controller run?

Up to 16 indoor units with the UTY-RNRUZ6, UTY-RSRYZ1 and UTY-RHRYZ1.

RSRYZ1 or RHRYZ1: what’s the difference?

The RSRYZ1 lets you pick the mode: heat, cool and the rest. The RHRYZ1 doesn’t: occupants only set the temperature, which suits hotels and common areas.

Is the UTY-RNRUZ5 still current?

Fujitsu replaced it with the UTY-RNRUZ6, which adds refrigerant-leak alerts and a sensor-replacement notice.

What’s Fujitsu’s warranty on controls?

Three years for wired controls, including the KAGAMI. Ninety days for wireless controls and Wi-Fi adapters.

Does a Wi-Fi control qualify for a rebate?

No. LogisVert funds the heat pump itself, not controls or thermostats.

FUJITSU thermostats and controls: run your heat pump from the wall or your phone.

Fujitsu doesn’t make “thermostats” in the usual sense: these are wall controllers, Wi-Fi adapters and interfaces built for its heat pumps. The right part depends on your indoor unit. Find it below.

01 · What to know

A control is a choice.

Seven facts from Fujitsu’s sheets, pages and warranty. Sources are at the bottom of the page.

Controls

Fujitsu doesn’t make "thermostats" in the usual sense: these are wall controllers, remotes and Wi-Fi adapters built for its heat pumps.

SSID

Your adapter’s Wi-Fi network name tells you the app: AP-WH or AP-WJ ending in E means AIRSTAGE Mobile; otherwise it’s FGLair.

Kit

The Altair 500 and Orion XLTH wall units need a communication kit for any wired controller.

24 V

The UTY-TTRXZ1 interface lets you keep your 24 V thermostat, as long as it’s the only control.

3 years

Fujitsu warrants its wired controls for three years and its Wi-Fi adapters for 90 days.

Successors

Three wall controllers have a successor with refrigerant-leak alerts: RSRY to RSRYZ1, RHRY to RHRYZ1, RNRUZ5 to RNRUZ6.

J-7S

The KAGAMI controller isn’t listed for the J-7S VRF, according to Fujitsu.

02 · Find your control

Pick your unit.

The indoor unit’s model is on its nameplate. Pick its family: you see the controls Fujitsu names for it, and the kit if one is needed.

Item	What it does
UTY-RVRU	Wired wall controller with a colour touch screen and a light ring that changes colour with the mode. It’s set up over Bluetooth with the AIRSTAGE Remo Set app.
UTY-RNRUZ5	Wired wall controller with a backlit touch screen and a weekly schedule. Fujitsu replaced it with the UTY-RNRUZ6, which adds refrigerant-leak alerts.
UTY-RSRYZ1	Simple wall controller that lets you pick the mode, with refrigerant-leak alerts. It replaces the UTY-RSRY.
UTY-RHRYZ1	Simple wall controller where occupants set the temperature without changing the mode. It suits hotels and common areas, and it replaces the UTY-RHRY.
UTY-RSNUM	Simple wall controller for previous-generation Fujitsu units with 3-wire communication.
UTY-RVNUM	Programmable wall controller for previous-generation Fujitsu units with 3-wire communication.
UTY-RNBYU	Programmable wall controller for previous-generation Fujitsu units with 3-wire communication.
UTY-TFSXH4	Wi-Fi adapter that plugs into a wall unit’s USB port. You control the unit with the AIRSTAGE Mobile app.
UTY-TFSXJ4	Wi-Fi adapter for Fujitsu cassettes, ducted units and air handlers. You control the unit with the AIRSTAGE Mobile app.
FJ-AC-WIFI-1	Intesis Wi-Fi module wired straight to the indoor unit, so you can run the heat pump from an app.
FJ-IR-WIFI-1NA	Small wall module that talks to the heat pump by infrared, with no wiring into the unit. You control it with the Intesis Home app.
FJ-RC-WIFI-1BT	Intesis Wi-Fi module that connects to the indoor unit’s remote-control port.
UTY-TTRXZ1	Interface that lets your 24 V thermostat, such as a Nest or Honeywell, run a Fujitsu heat pump. It must be the only control on the system.
UTY-TWRXZ2	Kit installed in a wall unit so a wired controller can connect to it.
UTY-TWBXF1	Interface kit to connect a wired controller to some previous-generation Fujitsu wall units.
UTY-XSZXZ1	Wall sensor that reads the temperature in the room rather than in the return air of a ducted unit.
UTY-XWZXZ5	Dry contact wire kit: remote on/off, plus run and error signals to another system.

Per Fujitsu’s sheets, unit by unit. A part missing from a list is not necessarily incompatible: Fujitsu just does not name it for that unit.

03 · Which app?

The network name tells you.

Your adapter’s Wi-Fi network name tells you which app to download.

Which app? Look at the adapter’s Wi-Fi network name

The network starts with AP-WH or AP-WJ and ends with E


Your app	AIRSTAGE Mobile
Accounts	5 per indoor unit
Features	Weekly timer, mode, fan speed, groups by building, floor or room

Another network name

Fujitsu’s rule: any other Fujitsu adapter network name means FGLair.

Your app	AIRSTAGE Remo Set
What it is for	Setting up and servicing the controller, over Bluetooth
Link	1 phone to 1 controller

It is not an app to run the heat pump remotely.

Good to know: a Wi-Fi adapter does not make the system “ENERGY STAR connected.” No Fujitsu heat-pump ENERGY STAR record read today carries that mention.

04 · The KAGAMI

Four colours, four modes.

The ring changes colour with the mode

Blue: cooling
Red: heating
Green: dry
Purple: auto

UTY-RVRU wired controller with a colour touch screen, set up over Bluetooth. Fujitsu does not list it for the J-7S VRF.

05 · From remote to building

Five ways to control.

Remote

The wireless remote, or a UTY-LBTUM, UTY-LBTUC or UTY-LNTU receiver depending on the unit.

Wall control

UTY-RHRYZ1, UTY-RSRYZ1, UTY-RNRUZ6 or the KAGAMI UTY-RVRU.

App

UTY-TFSXH4 or UTY-TFSXJ4 adapters, Intesis modules, or built-in Wi-Fi.

Central control

Several units in one building, on one Fujitsu controller.

Building system

Modbus and BACnet gateways. Integration is planned at quote time.

06 · The new models

Three controls, with leak alerts.

With R-32, Fujitsu added refrigerant-leak alerts to its wall controllers.

UTY-RSRY → UTY-RSRYZ1

Adds: refrigerant-leak alerts.

UTY-RHRY → UTY-RHRYZ1

Adds: refrigerant-leak alerts.

UTY-RNRUZ5 → UTY-RNRUZ6

Adds: refrigerant-leak alerts, sensor-replacement notice, emergency heat control, occupancy-sensor setting.

According to Fujitsu. The UTY-RNRUZ5 in our shop is replaced by the UTY-RNRUZ6: we offer the current model at quote time.

07 · Keeping your thermostat

Possible, if it is alone.

UTY-TTRXZ1: according to Fujitsu, this interface “may not be used with any other type of controls”: central controller, wired or wireless remote, Wi-Fi adapter or building interface. The TTRXZ1-KIT includes the interface, a plug and a 24 V transformer.
