PAC-USWHS002-WF-2 Wi-Fi Kit

Note that Mitsubishi's PAC-USWHS002-WF-2 Wireless Interface is only compatible with encrypted 2.4 GHz b/g/n protocols Wi-Fi networks. It cannot be used with 2.4GHz & 5GHz mesh networks. Your router should be able to support 2.4 GHz and b/g/n protocols. So routers configured to support ONLY Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax) or Wi-Fi 6E (802.11ax at 6 GHz) will not work.

You need to confirm the compatibility with your Mitsubishi mini-split from the chart here before making a purchase. Contact us for compatibility questions or router selection should you have challenges confirming the frequency band supported by your router.

PAC-USWHS002-WF-2 can be used together with the MHK2 wireless thermostat simultaneously or as a standalone.

Follow the below steps to set up your wireless interface:
  1. Power down all systems (At the unit and circuit breaker)
  2. Remove the cover to gain access to the control board
  3. Connect a Mitsubishi Electric wireless interface to the CN105 connector on the indoor unit board
  4. Return the cover and power up all systems
  5. At this stage, you should now be able to see a steady green light and four quick blue flashes indicating Bluetooth LE configuration mode. The interface is ready to connect using the app. Three slow, blue flashes repeat after the Connection is complete.
  6. Turn on Bluetooth in phone/tablet settings. Log into the 2.4 GHz WiFi network only, if previously logged in to the 5 GHz network, go into your WiFi settings and forget this network.
