For URC dealers & integrators

Scotchtown HVAC Bridge

Two-way control of Fujitsu Airstage mini-splits from URC Total Control. The bridge connects Fujitsu Airstage Wi-Fi adapters to URC, and URC's built-in two-way thermostat module drives it, so you program it in Accelerator like any supported thermostat. Nothing extra runs on the URC controller.

  • Installs on the client's LAN: no cloud account, no monthly fee
  • One license per URC controller. Move it to a new controller any time by deactivating it first.
  • Activation instructions emailed right after checkout

How it works

1

URC system controller

Your MRX uses URC's built-in two-way thermostat module in Accelerator 3. Nothing extra is loaded on the MRX.

⇄
2

Scotchtown HVAC Bridge

Runs on the client's NAS or PC (Docker) or on our plug-in appliance. It translates between URC and each unit's Airstage Wi-Fi adapter.

⇄
3

Mini-splits & HVAC

Talks to each indoor unit's Wi-Fi adapter over the local network and reports its state back to URC every 10 seconds.

True two-way

Power, mode, setpoint, fan and room temperature show live on every URC screen, so the interface always matches the unit.

Local and fast

No cloud hop. Commands and status stay on the client's network. The bridge checks its license online once a day. If it can't reach us, control keeps working for 60 days, then stops; status readings always keep working. Activation and moving a license need internet.

Room-by-room

Each head maps to a URC room, ready for macros, scenes and "House Off" style automations.
