After connecting the Wi-Fi interface to the air conditioner, connect the Wi-Fi interface to the access
point (to communicate with the server).
For this Wi-Fi interface, the use of WPS-Push is recommended. (Refer to 6.)
1) Hold down the WPS switch on the Wi-Fi interface for about 2 seconds to activate WPS-Push.
When WPS-Push on the Wi-Fi interface is ready to communicate with the access point, LED 1
blinks at a 0.5-second interval.
2) Activate WPS-Push on the access point.
3) When WPS-Push is successfully enabled, LED 1 lights up for 5 seconds. If it failed, LED 2 lights up
for 5 seconds, so try again from step 1.
Main Causes that WPS failed are as follows.
Comunication distance (from the Wi-Fi interface to access point), access point settings
(encryption, authentication, limit of connections, etc.)
Refer to the instruction manual for more information.
