Overview
The UTY-RVNYN touch panel wired remote controller allows configuration and system management through a protected settings interface.
If the management password is forgotten or needs to be reconfigured, it can be reset directly via the controller’s hardware buttons.
1. Accessing Password Reset Screen
Navigate to the Password Verification Screen on the controller display:
From the main menu:
Menu → Submenu → Initial
On this screen, simultaneously press and hold the following buttons for 2 seconds or more:
Cancel (✖) button
Menu (☰) button
The controller will emit a confirmation tone (beep) after a successful press duration.
2. Resetting the Management Password
After holding the buttons, the “Enter New Password” screen will automatically appear.
Enter a new 4-digit management password of your choice.
Confirm and save the entry to complete the reset process.
⚠️ Important: Once a new password is registered, the previous one becomes invalid. Ensure the new code is recorded securely for future service access.
3. Button Reference (see illustration)
| Ref. No. | Button Name / Function | Description |
|---|---|---|
| (3) | Menu Button | Opens main and submenu configuration pages |
| (4) | Cancel Button | Used for exiting menus or initiating password reset |
| (5) | Confirm / Enter Button | Finalizes input selections |
(As shown in the image above: hold buttons (3) + (4) together for ≥2 seconds to reset password.)
4. Notes
This procedure applies to UTY-RVNYM controllers supplied with Fujitsu VRF and ducted commercial systems.
The password reset is local only and does not affect any network or central control passwords.
If the controller remains unresponsive during the reset attempt, cycle power to the indoor unit and retry.
