Quick facts
The Fujitsu UTY-XWZX dry contact kit is the original harness that connects a Fujitsu AIRSTAGE heat pump to an external device. Fujitsu calls it the “External Wire Kit” in its accessory lists. It provides two functions: an on/off input by dry contact and a run status output.
Start or stop the heat pump with a contact
When the contact wired to the orange and yellow wires closes, the unit starts; when it opens, the unit stops. The contact connected to the blue and violet wires closes while the unit is running, which lets you turn on an indicator light or signal a controller. It is the simple solution for a hotel key card, an occupancy sensor, a window contact or a timer.
Electrical specifications
- Input: field-supplied dry contact, 12 V DC, 10 mA
- Output: 24 V DC maximum, 10 mA to 1 A
- Not supported: mode, set point, fan speed and detailed error codes
Units listed by Fujitsu
In the R-32 H series, Fujitsu lists it for the Altair 500 (ASUH**KPAS), Orion XLTH (ASUH**KZAS) and Orion XLTH+ wall units, as well as the AGUH**KUAS floor units. Cassettes and ducted units use the UTY-XWZXZG instead. If you need an error output, choose the UTY-XWZXZ5.

Frequently asked questions
Is my Fujitsu unit compatible?
Fujitsu lists the UTY-XWZX among the accessories of its Altair 500 (ASUH**KPAS), Orion XLTH (ASUH**KZAS) and Orion XLTH+ wall-mount units and its AGUH**KUAS floor units. Cassettes and ducted units use the UTY-XWZXZG. Send us your model number and we confirm.
How is it different from the UTY-XWZXZ5?
The UTY-XWZX handles on/off and reports run status. The UTY-XWZXZ5 adds an error output and lets the input act as a forced stop.
Can it set the temperature?
No. It carries no mode, setpoint or fan speed. For full control you need an interface such as the UTY-VMSX Modbus converter or the UTY-TTRXZ1 thermostat interface.
Can you install it?
Yes. Our technicians connect it to the unit’s board and to your external contact, everywhere in Greater Montréal.
