AIRSTAGE VRF Systems Adapters & Converters

Converter / Adapter (for system expansion)

Network Converter

UTY-VTGX (DC power supply type)

Network Converters add Fujitsu mini-split control to the VRF communication network.

Signal Amplifier

UTY-VSGXZ1

  • Transmission Line length can be extended up to 11,811ft. (3,600m) with multiple Signal Amplifiers.
  • Up to 8 signal amplifiers can be installed in a VRF network system.
  • A signal amplifier is required, (1) When the total wiring length of the transnission line exceeds 1,640ft. (500m). (2) When the total number of units on the transnission line exceeds 64.

External Switch Controller

UTY-TERX

  • In combination with a field supply Card-Key Switch or other sensor, the External Switch Controller allows control of the ON / OFF, Room temperature, Fan speed and Master control functions. This makes this product suitable for installations such as hotel rooms.
  • Card-key or other sensor switches are available as a locally purchased parts.
  • 2-wire type
  • The set temperature can be specified at two points for cooling and heating individually (4 points).

External Power Supply

UTZ-GXXA

  • This product supplies power to the PCB of the indoor unit when the indoor unit is turned off in order to prevent communication error and stop of the EEV valve.
  • This is great for multi-tenant application when a tenant may turn off power to the indoor unit.
