Installation and operation manual for the Simply Automated Fixture Relay Module (UFR), a UPB load-control module.
Installation and operation manual for the Simply Automated Fixture Relay Module, model UFR — a UPB (Universal Powerline Bus) load-control module that turns 120VAC appliances or lighting ON and OFF (including timed OFF) based on digital commands received over existing power wiring.
The Fixture Relay Module (UFR) turns 120VAC appliances or lighting ON and OFF (and timed OFF) based on digital commands received over the power wiring from a remote UPB controller. UPB controllers and modules can be freely located anywhere in the home — no additional wiring is required and no radio frequency signals are used for communication.
The Fixture Relay Module is designed for indoor use with devices permanently wired into the home electrical system. Note: the controlled device's power rating must not exceed 12 amps.
Note: The UFR has two neutral wires for convenience — cap the second neutral wire if unused. Cap unused brown/white and/or red/white wires to prevent shock or shorting. When using an optional USR Dedicated Remote Switch, connect the brown wire (black on some models) as shown in the wiring diagrams to enable operation of the LED indicator — this wire is not required for switch operation and can be omitted if a third wire is not available (cap it if not used).
Caution: Do not insert metal objects into the module — especially into the Program Switch — while it is connected to power.
The Fixture Relay Module operates according to commands sent by a controller. The indicator on the module glows RED when the controlled device is OFF and GREEN when the device is ON.
A Timer function is available on the UFR: controller commands can turn ON the UFR and load a preset timer period, after which the UFR automatically turns OFF. Available preset times: 1 Sec., 5 Sec., 30 Sec., 1 Min., 2 Min., 4 Min., 10 Min., 20 Min., 30 Min., 40 Min., 50 Min., 1 Hr., 2 Hrs., 3 Hrs., and 4 Hrs.
When the UFR is controlled by a remote switch (model USR), local response time adjustments are available (300, 450, 600, and the default 750 mSec), configured with UPStart software. Local response time is the time from rocker press to load response.
To restore the following default settings, place the UFR in SETUP mode and press the Program Switch ten times, then press the switch twice more to exit this mode.

The UFR (and its dimmer counterpart, the UFD) is wired to line and neutral, and controlled via link(s) transmitted from a US1, US2, or control system (hardwired or software) — with an optional USR Dedicated Remote Switch for local control. Full wiring diagrams for both configurations are included in the downloadable PDF.
