Hunter UCH — The Site Hub That Puts SkyCommand on Centralus
The Hunter UCH is the Universal Communication Hub for SkyCommand. One hub per site. It takes 120/230 VAC, mounts on an exterior wall, and holds two plug-in A2C modules: a cloud module (Wi-Fi, Ethernet, or LTE) and the A2C-LORA field radio that talks to BOC controllers. Pair with a phone over Bluetooth to join the network, then finish programming in Centralus. The sliding door, key lock, and rain-sensor terminals are built in. A 1.5 in hole saw for BOC lid installs ships with every UCH.

Frequently Asked Questions
What modules do I have to order with the UCH?
Order A2C-LORA for field radios, plus exactly one cloud module: A2C-WIFI, A2C-LAN, or A2C-LTEM. Modules are sold separately. A2C-LORA is not for ACC2 — UCH only.
Does the UCH replace an ACC2 controller?
No. UCH is the SkyCommand site hub. Centralus can manage SkyCommand sites alongside ACC2, ICC2, MCC, and Pro-C controllers. It is not a 24 VAC station controller.
Can I mount the UCH indoors?
You can, but the LoRa antenna must be outdoors. Hunter recommends ANT-EXT-KIT (9 ft cable, 25 ft max with low-loss extension) for indoor hubs and for better range.
How do I add the UCH to Centralus?
Power the hub, install both modules, press the Bluetooth pairing button, and finish setup on a phone with Bluetooth and Location Services on. The UCH then appears in Centralus as a new site so you can add BOC devices.
