The document “UTY-DTGY Part 2” continues the operating manual for the Airstage Touch Panel Controller (UTY-DTGY / UTY-DTGG) produced by Fujitsu General Limited. This second part (pages 51–95) builds upon Part 1, detailing advanced setup, configuration, troubleshooting, and system maintenance.

1. Scheduling and Custom Settings (Chapters 3-4, pages 51–57)

This section expands on scheduling functions:

  • Creating, editing, and deleting operation patterns: Users can define, modify, or remove air conditioning operation schedules based on date, time, or custom conditions.

  • Calendar and custom schedules: Offers flexibility through:

    • Annual, monthly, or weekly patterns.

    • Custom day prioritization, allowing control over which schedule takes precedence (e.g., holidays vs. workdays).

  • Schedule Examples (page 56): Illustrations show typical workday cooling/heating operations from 8:40 a.m. to 5:30 p.m., with temperature holds and lockup periods.

  • Allocation Methods: Schedules can be distributed across multiple units or grouped systems using “Calendar” or “Custom” allocation.

2. Password and Access Management (pages 58–63)

A comprehensive security framework allows layered access control:

  • Four password categories:

    • User Setting/History

    • Operation Setting

    • Schedule Setting

    • Group Setting

  • Default password: VRVFRF

  • Access Rights: Separate passwords can restrict access to system setup, scheduling, and operation control.

  • Password reset instructions: Included for administrators; local dealer contact is required if lost.

3. Installer Settings (pages 64–80)

This section targets HVAC installers and system integrators:

  • Address Registration: Defines and registers indoor units, refrigerant circuits, and remote controller addresses.

  • Automatic vs. Manual Registration: Indoor units can be registered in sequential or manual order.
    (See pages 67–71 for detailed procedures.)

  • Import/Export Capabilities:

    • Configuration data can be stored or restored using USB memory.

    • Data can be created or edited via PC using the provided “File Making Sheet” (Excel-based).

  • External Input Settings:
    Configurable triggers include:

    • Emergency Stop

    • All On/Off

    • Pulse Input

    • Temperature Control Range Limitation

  • Temperature Display Units: Switchable between °C and °F (page 77).

  • Temperature Range Limits: Adjustable from 10–30°C (48–86°F) per mode and operation type (page 78).

  • Remote Controller Restrictions: Certain local remotes can be disabled for centralized control (page 79).

4. Preference Settings (Chapter 4, pages 81–86)

Provides customization for the touch panel interface:

  • Panel Calibration: Ensures accurate touchscreen response.

  • Backlight & Brightness: Adjustable brightness and automatic dimming based on user activity or system errors.

  • Audible Feedback: Option to enable/disable beeps for standard operations or alarms.

  • Panel Cleaning Mode: Temporarily locks touch input for safe screen cleaning.

5. System History and Logging (Chapter 5, pages 87–93)

The controller maintains detailed operation and error logs:

  • Error History: Displays last 10 errors per indoor unit (page 89).

  • Status History: Records temperature, mode, and operation state (up to 100 entries).

  • Operation History: Tracks changes made from the touch panel and other devices.

  • Data Export: All histories (error, status, operation) can be exported to USB for diagnostic review.

  • Version Screen: Displays software version information for maintenance verification (page 93).

6. Technical Reference (Chapter 6, pages 94–95)

  • Dimensions:
    246 mm (W) × 205 mm (H) × 64 mm (D).
    Illustrated on page 94 for mounting reference.

  • Specifications:

    • Power Supply: 1 A AC100–240 V, 50/60 Hz

    • Power Consumption: 22 W

    • Display: 7.5-inch TFT color LCD (640×480 pixels)

    • Operating Temp Range: 0–40°C

    • Storage Temp Range: –20 to 60°C

    • Interface: EXT IN/OUT for network or emergency stop linkage.

  • Error Codes (page 95): Lists major controller faults such as:

    • 161: Transmission PCR error

    • 163: LAN communication error

    • 164–166: PCB or internal transmission errors

    • CF1: External connector error

7. Summary

Part 2 of the UTY-DTGY Touch Panel Controller Manual focuses on:

  • Advanced installer and service configurations

  • Data management and diagnostics

  • User interface preferences

  • Comprehensive maintenance and troubleshooting guidance

It effectively completes the first part by providing installation, configuration, and operational continuity for technicians and administrators overseeing large-scale, multi-zone HVAC networks.
