Hello Pro HVAC'ers! My Kumo Cloud Wireless Interface PAC-USWHS002-WF-2 like the one in the link here (https://shop.rfwel.com/mitsubishi-electric-pac-uswhs002-wf-2-wireless-wi-fi-interface-control-2/) has a problem. LEDs don't light on anymore. They were on for three days after installation and all of a sudden they turned OFF. What can I do to fix it? Please help!
