Complete installation, configuration, and troubleshooting manual for the Simply Automated SimplyBrilliant UPB Scene Controller, model UCQT-40.
Complete installation and configuration manual for the Simply Automated SimplyBrilliant® UPB Scene Controller Base, model UCQT-40 (and UCQT-40-W with white 4-oval-button faceplate) — a 4-button, 4-status-LED scene controller for UPB (Universal Powerline Bus) lighting scenes and devices.
The UCQT-40 controls and tracks the status of UPB lighting scenes and UPB devices. It does not have a local light-circuit output — actual load control is handled by other UPB devices (dimmers, relays, low-voltage I/O modules) that provide direct load circuit control. The UCQT tracks and triggers those devices via UPB scene links.
The removable 4-button faceplate (with 4 lightpipes) can be swapped for color changes without disconnecting the switch — available in oval (ZS24OS Series) or thin-bar (ZS24BS Series) button styles, in white, almond, light almond, ivory, brown, and black.
With UPStart UPB configuration software and a Computer Interface Module (UMC Series), the 4 buttons can be configured to dim, fade up/down, turn on/off, blink, activate countdown timers, and recall light levels via UPB scene links. The 4 LEDs support up to 8 presets (receive components) for up to 8 scene links, and can be configured to indicate scene status or the state of an individual device within a scene.
The UCQT-40 is designed for installation in a junction box wired to a readily accessible over-current protection device per NEC/CEC electrical codes.
Note: Since the UCQT-40 doesn't directly control a circuit load, if the j-box position has a switch-leg load circuit that needs on/off/dim control, consider:
Configuration requires UPStart UPB setup software and a UMC Computer Interface Module (download the latest version from Simply-Automated.com; first-time users should use the Quick Start Guide and Installation Wizard).
To place the UCQT in SETUP mode (required for self-identification on the powerline): tap any button 5 times quickly. The power LED blinks continuously GREEN in SETUP mode. To exit and return to NORMAL mode, tap any button 2 times quickly.
| Network Name | "Network 1" |
| Room Name | "New Room Name" |
| Device Name | "New UCQT-40" |
| Unit ID | 50 |
| Network ID | 255 |
| Network Password | 1234 |
| Transmit Links | Buttons 1-4 = Links 001-004 |
| Receive Links | Presets 1-4 = Links 001-004, LEDs 1-4 ON; Presets 5-8 = Unused |
Factory reset: In SETUP mode, tap any button 10 times — the LED blinks continuously RED. Tap any button 2 times to exit RESET mode.
Default button mode is "Super Multi-button." Default button behavior:
| Button Event | Scene Controller Action (default) |
|---|---|
| Single-Tap | Activate Scene Link |
| Double-Tap | Deactivate Scene Link |
| Hold | Start dim fading at Default Rate; toggles between fading up or down |
| Release | Stops fading and holds current level |
Linking a UCQT button to a non-dimming device (Receptacle, Appliance Module, Relay Module) turns the load ON with one tap and OFF with two taps. Linking to a dimming device (Switch, Lamp, or Fixture Dimmer Module) follows the table above.
Countdown timer: Available on all Simply Automated UPB products except models US2-40, UML/A-E, and UMI-32. Preset times: 1 Sec, 5 Sec, 30 Sec, 1/2/4/10/20/30/40/50 Min, 1/2/3/4 Hr. Default is Timer Off.
Once initially configured via software, scenes can be adjusted without a computer:
To install: Fit the light pipe (LED recess) at the top of the rocker faceplate, align the four side prongs with the switch body's slots, then press evenly on top and bottom until all four prongs fully latch. Exercise the rocker several times to confirm proper operation.
To remove: Remove the wall plate. Press the top two prongs inward to unlatch and release the top of the assembly, then press the two lower prongs inward and pull the faceplate away and slightly downward from the switch body.
| Problem | Probable Cause | Solution |
|---|---|---|
| No power (LED indicator OFF) | Circuit breaker open, not providing power | Check the circuit breaker is on. If still not lit, check for 120VAC at the wire nuts connecting power. |
| Push button doesn't transmit scene link (no faint buzz) | Faceplate not seated properly, or no scene link programmed into transmit component table | Exercise/reseat the faceplate. In UPStart, double-click the device icon to open Edit Device and check the transmit component table for an assigned link. |
| Buttons stick or don't actuate properly | Mounting screws too tight/j-box deformed, warping the switch body; or actuator springs backed out during shipping | Loosen mounting screws to relieve pressure. Exercise the button several times; remove/replace faceplate if needed. |
