Fujitsu General Australia

Overview

This reference chart outlines the external output specifications for Fujitsu General VRF indoor and outdoor units, including Compact Cassette, Ducted, Ceiling, Wall-Mounted, and Controller types. It details signal type, available functions, terminal assignments, and wiring limitations for system integration and auxiliary equipment control.

Functions Supported

Depending on the model and configuration, the following external output functions may be available:

• Operation Status Output

• Error Status Output

• Filter Sign Output

• Auxiliary Heater Output

• Base Heater Output

Each function can be configured as either a dry contact output or an applied voltage output depending on the indoor or outdoor model type.

Electrical Characteristics

Wiring and Connector Information

• Terminal locations: D91/92, D101/102, D121/122, or equivalent depending on model series.

• Recommended Cable: AWG22 (Twisted Pair 0.32 mm²).

• Maximum Cable Length:

  • Dry Contact: 25 m or less

  • Applied Voltage: 150 m or less

Note: When using the auxiliary heater output, ensure that DIP switch SW12-9 is set to ON as indicated in the specification notes.
