1. Overview
Part 2 completes the operating manual for the UTY-DTGY / UTY-DTGG Touch Panel Controller. It covers advanced schedule allocation, password protection, indoor-unit registration, external input configuration, controller preferences, system history, data export and technical specifications.
| Section | Manual pages | Main content |
|---|---|---|
| Schedule continuation | 51–57 | Operation patterns, calendar allocation, custom days and schedule priority. |
| Password settings | 58–63 | Access rights and password changes for users and operators. |
| Installer settings | 64–80 | Addressing, registration, USB transfer, external inputs and control restrictions. |
| Preference settings | 81–86 | Calibration, backlight, sound and panel-cleaning mode. |
| History | 87–93 | Error, status and operation history, export and version information. |
| Technical reference | 94–95 | Dimensions, specifications and controller error codes. |
2. Scheduling and Custom Settings
The controller allows operation patterns to be created, changed, copied or deleted, then assigned through the normal calendar or by custom-date rules.
| Function | Use |
|---|---|
| Operation pattern | Sets time, On/Off state, mode, temperature and remote-controller restriction. |
| Calendar setting | Assigns patterns by date or day of week across the displayed calendar period. |
| Custom setting | Creates annual, monthly, weekly or specific-day exceptions such as holidays or shutdown periods. |
| Priority order | Where calendar and custom settings overlap, the item higher in the custom-setting list has priority. |
Schedule capacity: Up to 30 schedules can be created. Each schedule can include multiple daily operation points and can be applied to individual remote-controller groups or larger groups.
Important: Review the custom-setting priority whenever holiday, seasonal or special-event schedules are added. A higher-priority custom rule can override the normal weekly calendar.
3. Password and Access Management
Password protection can be applied to separate controller functions so that everyday users can operate the system without accessing higher-level configuration.
| Password category | Controls access to |
|---|---|
| User Setting / History | Preference, history and selected user-setting functions. |
| Operation Setting | On/Off, mode, temperature and other operational changes. |
| Schedule Setting | Creating or modifying schedules. |
| Group Setting | Changes to the group hierarchy and group composition. |
Factory default password: VRVFRF
Password control: Record changed passwords in an approved secure location. If a password is forgotten, subsequent access to the protected function may not be possible and the local dealer may need to be contacted.
4. Installer Settings
4.1 Touch Panel Controller Address
The main controller address can be set from 00 to 15. Where two or more touch panel controllers are installed, ensure every controller uses a unique address.
4.2 Indoor Unit Registration
Indoor units can be registered using several methods:
| Registration method | Description |
|---|---|
| Address order | Automatically registers units in ascending refrigerant-system address order. |
| Operation order | Registers units in the order they are operated during the registration process. |
| Manual registration | Adds or deletes specific remote-controller groups by address. |
| External input data | Imports registration data from USB memory. |
Registration caution: Adding, deleting or re-registering indoor units can affect group settings and schedules. Confirm the group hierarchy and schedule allocation after registration work is completed.
4.3 USB Import and Export
Indoor-unit registration and system configuration files can be exported to USB memory, edited using the supplied PC file-making sheet, and imported back into the controller.
Good practice: Export and retain a current backup before changing system registration, group structure, schedules or installer parameters.
4.4 External Input Settings
The external input can be configured for:
| Emergency Stop | Stops the controlled system from an external signal. |
| All On / All Off | Starts or stops all applicable units from an external signal. |
| Signal type | Edge or pulse input, depending on the selected function. |
| Not Used | Disables operation by external input. |
4.5 Temperature and Local-Control Restrictions
- Temperature display can be set to Celsius or Fahrenheit.
- Settable temperature ranges can be applied to all modes or individually to Auto, Cool/Dry and Heat.
- The manual identifies a controller setpoint range of 18–30°C for Auto/Cool/Dry and 10–30°C for Heat.
- Remote-controller operation prohibition can be enabled to prevent selected local-controller operations.
5. Preference Settings
| Setting | Purpose |
|---|---|
| Panel calibration | Corrects touch-position offset using the five-point calibration process. |
| Automatic backlight timer | Turns the backlight off after a selected period from 1 to 60 minutes, or disables the timer. |
| Error backlight | Automatically illuminates the panel when an error occurs. |
| Brightness | Three brightness levels are available. |
| Operation beep | Enables or disables normal touch confirmation sounds. |
| Error alarm beep | Enables or disables the audible error alarm. |
| Panel cleaning mode | Temporarily changes the active touch area so each half of the screen can be cleaned safely. |
6. History, Logging and Diagnostics
| History type | Information available |
|---|---|
| Error History | Indoor-unit, outdoor-unit and touch-panel errors. Up to the latest 10 errors are displayed for each indoor unit. |
| Status History | Up to 100 records of date, time, On/Off state, mode, set temperature, airflow and other group status. |
| Operation History | Up to 100 records of changes made from the touch panel and other devices. |
| Version | Displays the touch panel controller software version. |
Diagnostic workflow: Before deleting history, export the relevant error, status or operation records to USB and attach them to the service case where required.
