Touch Panel Controller (UTY-DTGYZ1)
Centralised control, remote monitoring and electricity charge apportionment
Training overview for Fujitsu General VRF applications
The UTY-DTGYZ1 Touch Panel Controller is a high-specification central controller designed for small to medium commercial projects. It combines system monitoring, centralised operation, remote access, energy management and optional tenant billing functions in a single platform.
Training note: Available functions depend on the connected equipment, system design, controller configuration and optional accessories. Always confirm compatibility using the current product documentation before specifying or commissioning the controller.
1. Product purpose and development background
The UTY-DTGYZ1 Touch Panel Controller, commonly referred to as the TPC, was developed as an advanced central controller for small to medium commercial projects. It builds on the previous Touch Panel Controller by combining monitoring, control and energy-management capabilities within one interface.
The controller responds to growing demand for centralised system visibility, remote operation and more detailed tenant-level energy management in commercial and multi-tenant buildings.
2. Key enhancements compared with the previous model
| Enhancement | Business benefit |
|---|---|
| LAN/WAN remote access | Allows authorised users to monitor and control the system remotely through a standard web browser. |
| Electricity charge apportionment | Supports tenant-level electricity cost allocation, including separate heating and cooling calculations. |
| Automatic summer time adjustment | Synchronises daylight saving changes across connected controllers. |
| Outdoor unit low noise control | Allows low noise mode to be enabled or disabled from the TPC interface. |
| Automatic error email | Provides faster fault awareness by sending system and error details to nominated recipients. |
Key differentiator: The electricity charge apportionment function supports separate heating and cooling cost calculations, providing greater billing detail for multi-tenant applications.
3. Compatibility and system capacity
| Item | Specification |
|---|---|
| Applicable systems | Fujitsu General VRF S, V and J series |
| Maximum connected indoor units | 64 indoor units |
| Network connection | LAN or WAN using Ethernet |
| Remote user devices | PC, tablet or smartphone |
| Browser access | Internet Explorer, Chrome, Firefox and Safari, subject to version and device compatibility |
4. Remote monitoring and control
Remote access is provided through a standard web browser without requiring specialised monitoring software. Depending on user permissions and system configuration, authorised users can view and adjust:
- Indoor unit ON/OFF status.
- Operating mode, including cooling, heating and automatic operation.
- Temperature setpoint.
- Airflow and fan settings.
- Filter reset status.
- Energy-saving functions.
- System faults and error history.
Automatic fault email content
Where email notification is configured, the alert can include:
- Project name.
- Unit address.
- Error code.
- Model name.
- Date and time of the fault.
Tenant access: User access can be restricted so that a tenant or facility user can monitor and control only the indoor units allocated to them.
Browser compatibility: Smartphone access is supported; however, correct display and operation cannot be guaranteed across every browser, operating system or device version.
5. Electricity charge apportionment function
The optional Electricity Charge Apportionment function calculates and distributes energy usage between tenants. Outdoor unit power consumption is measured and apportioned using indoor unit operating information.
Required components
| Component | Function |
|---|---|
| UTY-DTGYZ1 controller | Collects system operation and meter data. |
| UTY-PTGXA kit | Optional Electricity Charge Apportionment activation kit. |
| Electricity meter | Connects to CH1 using the K1 and K2 terminals. |
| PC | Runs the Electricity Charge Apportionment Tool and generates billing outputs. |
| USB activation key | Activates the ECA function for one controller. |
Billing workflow
Electricity meter → Touch Panel Controller → PC with ECA Tool → Tenant billing statement
The meter sends electricity-use data to the TPC. The TPC combines this with system operating information, and the ECA Tool processes the data to calculate tenant charges and generate billing statements, including separate heating and cooling allocations.USB activation restriction: Each USB key activates the Electricity Charge Apportionment function for one TPC only. Once activated, it cannot be reused on another controller. If the controller is replaced, the ECA function must be reactivated in accordance with the applicable replacement procedure.
6. Automatic summer time setting
The controller can be programmed with daylight saving start and end dates. Once enabled, the TPC automatically updates the time setting across connected remote controllers.
Configuration must be completed in accordance with the UTY-DTGYZ1 operation manual.
7. Outdoor unit low noise setting
Low noise mode can be enabled or disabled from the TPC interface, removing the need to adjust the setting only at the outdoor unit.
Setting priority: Where the TPC and outdoor unit settings conflict, the outdoor unit setting takes priority.
8. Technical specifications
| Feature | Specification |
|---|---|
| Network connection | LAN / WAN Ethernet |
| Maximum indoor units | 64 |
| Browser compatibility | Internet Explorer, Chrome, Firefox and Safari, subject to version compatibility |
| Power supply | 240 V AC |
| External inputs | CH1 to CH4 |
| USB port | ECA activation and service maintenance |
| Optional accessory | UTY-PTGXA Electricity Charge Apportionment Kit |
9. Common training questions
| Question | Answer |
|---|---|
| Can the TPC connect directly to an electricity meter? | Yes. The meter connects through CH1 using terminals K1 and K2. Additional metering requirements may require further system design or controllers. |
| Can the USB activation key be copied? | No. The key is protected and intended for single-controller activation. |
| What happens if the controller is replaced? | The replacement TPC must be reactivated for the Electricity Charge Apportionment function in accordance with the applicable service procedure. |
| Can the ECA Tool run on Windows 10? | The training material identifies support from Windows Vista through Windows 10. Confirm current software compatibility before installation. |
| Which browsers can be used for remote access? | Internet Explorer, Chrome, Firefox and Safari are identified, subject to browser and device version compatibility. |
| Which low noise setting has priority? | The outdoor unit setting has priority where both the outdoor unit and TPC have been configured. |
