Summary: Installation Manual – Wired Remote Controller UTY-RNNYN
1. Overview
The document is an installation manual intended for authorized service personnel installing the UTY-RNNYN wired remote controller for air conditioners. It outlines safety precautions, installation steps, electrical requirements, function settings, and error diagnostics.
2. Safety & Electrical Requirements
Installation must comply with national electrical standards.
The controller must not be powered until all wiring is complete.
The room temperature sensor should be positioned away from direct sunlight, airflow outlets, and heat sources.
Wiring must be isolated from power and signal lines to avoid interference.
Recommended cable: 22 AWG, 3-core sheathed PVC shielded wire.
3. Parts & Accessories
Supplied components include:
Installation and operating manuals
Connecting cable
Tapping screws
Binder and cable clamper
These are used to secure the controller and connect it to the indoor unit.
4. Installation Procedures
Mounting: The controller’s front and rear cases are separated for installation. The connecting cable passes through the wall or mounting box and is secured with a binder.
DIP Switch Settings:
DIP switch 1-6 → ON (memory backup).
DIP 1-2 → ON for dual-controller setups.
Battery backup prevents data loss during power failures.
Cable Connection:
Two options:Using the provided connector cable.
Connecting directly to the indoor unit terminal block (as per model).
5. Installation Methods
Group Control: One remote can manage multiple indoor units (cassette, duct, or ceiling types). Each indoor unit must have a unique DIP-set address.
Dual Remote Control: Two remotes (master/slave) can control the same units; however, only the master uses timer and diagnostic functions.
6. Power-On & Temperature Detection
After power-up, the controller display initializes.
Two modes for temperature detection:
Indoor unit sensor (default)
Remote controller sensor (if Function 42 is enabled)
Note: Wall-mounted sensors can give inaccurate readings if wall temperatures differ significantly from room air.
7. Function Settings
Technicians can adjust multiple operational parameters by entering the function-setting mode using button combinations.
Key configurable items include:
| Function | Description | Function No. | Setting Values |
|---|---|---|---|
| Filter sign | Cleaning interval | 11 | 00–03 |
| Ceiling height | Adjusts airflow | 20 | 00–01 |
| Outlet direction | 3-way/4-way | 22 | 00–01 |
| Temperature correction | Fine-tunes heating/cooling | 30–31 | 00–03 |
| Auto restart | After power loss | 40 | 00–01 |
| Sensor selection | Indoor or remote | 42 | 00–01 |
| Signal code | Communication ID | 44 | 00–03 |
| External input | Stop or forced stop | 46 | 00–02 |
| Temperature control method | Unit vs. remote | 48 | 00–01 |
Each change must be confirmed and power cycled afterward.
8. Test Operation
To verify installation:
Turn off normal operation.
Press specific button combinations to start the test cycle (runs 60 minutes).
The display shows a “TEST” indication.
Press START/STOP to exit.
9. Error Codes
If a fault occurs:
Wired controllers display alphanumeric error codes.
Wireless systems signal errors through lamp blink patterns.
Common issues include:Communication errors
Sensor faults (temperature, pressure, compressor)
Fan or motor failures
Model or address mismatch
The table on page 9 lists detailed error indicators for each component.
10. Summary
This manual provides complete technical instructions for safely installing and configuring the UTY-RNNYN remote controller. It emphasizes proper wiring, DIP switch configuration, and function-specific programming to ensure accurate system control and diagnostic capability. The final section enables technicians to troubleshoot efficiently using standardized error codes.
