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.
