Why Is The Timer Light Blinking?

When the timer icon of the Panasonic wireless controller starts to blink, the problem usually lies in the internal setting of the indoor or outdoor unit.

For WL model CZ-RWSU1U, the problem can be diagnosed by the characteristic of the blinking icons. As for CZ-RTC5, the error code appears on the display screen.

The blinking timer icon only

A blinking timer icon mainly indicates compressor-related problems.

The error codes H01 to H05 and H31 might also show on the monitor of your remote control. It's best to call professionals for check-ups and services in such instances.

Along with the specific timer-icon error codes, we have also listed other errors with their blinking manifestation:

The first thing to do

Upon alarm, try to turn the unit off for about 1 minute, then restart it.

If the alarm disappears, then you can continue running the unit. But if it persists,  contact your dealer.

To access the error code history of your unit from its wired controllers, follow these steps:

1. Simultaneously press three buttons, the back arrow, the enter button, and the right arrow, to access the maintenance menu.
2. Select No. 6, which is the Service Check. The error code will be displayed there.

Why Is It Important To Set WL Controller's Address?

Cross-communication between one indoor unit and another unit's remote can happen. This is especially true when more than one indoor unit is installed in the same space. It is for this purpose that a remote address switch was created.

The address switch allows for a dedicated signal to prevent communication errors.

Guide to setting up your WL controller's address.

1. Press the ADR and loop buttons together. "SET" will then be displayed on the screen.
2. Holding the ADR button down while intermittently pressing the loop button allows you to browse the different address settings (ALL, 1, 2, 3,...6).
3. Once the desired receiver address switch is displayed, release the ADR button. The controller buzzer will sound if the setting corresponds with the receiver's address.

Before setting the address switch of your controller, the contractor must install the receiver in your indoor unit.

The contractor will be responsible for ensuring that the WL controller is mounted in a place that gives an uninterrupted signal to the indoor unit.

It is also crucial that the contractor leaves the operation manual with you and explains how to operate and care for the unit.

In Closing

Manipulating your AC indoor unit, like setting and canceling its timer and even diagnosing errors, is easy with the help of a reliable remote controller and manual.

However, while keeping yourself informed is to your advantage, it is not wise to attempt DIY repairs. It is always best to call your contractor for technical and mechanical issues.
