• For details of cabling/installation of the remote controller, refer to the Installation
Manual attached to the remote controller.
• When the remote controller is used for the first time, it accepts an operation approx. 5 minutes after the power
supply has been turned on. It is not a trouble, but is because the setup of the remote controller is being checked.
For the second power-ON time and after, approx. 1 minute is required to start the operation by the remote controller.
