Wiring Instructions
Control System Overview
Virtual Sun fixtures include an integrated control box mounted inside the enclosure alongside the power supply unit (PSU). The PSU provides low-voltage DC power to the control box.
Primary and Secondary Fixtures
- Primary fixture — identified by a "PRIMARY" label on the control box. Connect all external control cabling (0-10V, DALI, DMX, or Casambi) to the primary only.
- Secondary fixtures — require no control cabling. They receive brightness and color temperature from the primary over Ethernet and follow automatically.
Ethernet Synchronization
- Connect all fixtures in a group to a single dedicated unmanaged Ethernet switch (supplied by Innerscene for groups of 3 or more fixtures) using standard Cat5e/Cat6 cables.
- Use one switch per independent group. The switch must not be connected to the internet or to any network serving a different fixture group.
WiFi Programming
Virtual Sun supports the SkySync hub and mini-hub for WiFi-based scheduling, circadian animations, and scene control — the same system used by Circadian Sky.
Quick Test Power Cord
A power cord may be optionally supplied with your shipment to faciliate the testing of your light fixtures. You may wish to test the fixtures at ground level before hard wiring into ceilings. This power cord is normally packed in the Primary fixture box.
WARNING
In some areas, homeowners can perform this test without a licensed electrician. Consult your local codes.
Components
Process

Open driver box access panel with Phillips PH2 screw driver.


Remove 3x Wago wire clamps pre-attached to quick test power cord to expose copper conductors and set to one side.

Insert pigtail wires into Wago clamp on light fixture as shown below (3-way or 5-way connectors may be provided).
Brown to Black. Blue to White. Green/Yellow to Green. Do not connect dimming wires (Grey & Purple).


Plug the power cord into a building mains power socket to test each fixture power on properly.
Some dimming and control features may be available whilst powered from a socket.
WARNING
Unplug from mains power socket, then re-attach wago connectors to make safe.

DMX Wiring and Setup

for Installers
- If the fixture is at the end of the signal run then fixture to Termination. DIP switch on Daugterboard postition 1 to ON/UP.
- Set the same starting channel on the fixture as the DMX controller/console using the DIP switch. The DIP switch use Binary encoding, for example, channel 17 is 0000010000.
- By default the switches at all set to OFF and will not respond to DMX signals.
- First channel is Intensity/Dimming. Second channel is Color/Tuning. For example, if starting channel is set to 17, channel 17 is Dimming control (Intensity), channel 18 is Color control (CT).
VIRTUAL SUN DMX DAUGHTERBOARD

⚠ Wireless Group Installation
Innerscene Virtual Sun fixtures are organized into wireless groups. Each group has one Primary fixture that receives the external control signal (0-10V, DMX, DALI, or Casambi) and synchronizes brightness and color temperature to its Secondary fixtures over a dedicated Ethernet connection.
Z0 / Z1 — Single fixture
No Ethernet, no secondaries. The fixture receives control directly.
Z2 — Direct Ethernet
Two-fixture group: connect primary ↔ secondary directly with one Cat5e/Cat6 cable.
3+ Fixtures — Switch
Innerscene supplies an Ethernet switch. Connect all fixtures in the group to that switch only.
Installation Steps
⚠ Avoid These Mistakes
- Connecting the Ethernet switch to the building network or internet
- Mixing fixtures from different groups on the same switch
- Wiring control inputs to a Secondary instead of the Primary
- Skipping Ethernet for a Z2 group — they will not sync without it
Specify the distance between fixtures when ordering so Innerscene can supply Ethernet cables of the appropriate length.
Clearance
See below for recommended clearance between the fixture or fixtures and surrounding structure or insulation.

Innerscene A7 light fixtures have internal smart thermal protection.
When any fixture within a group become too hot it will automatically
reduce the brightness of the group. When the temperature becomes
excessively high, power will be cut-off from the fixture until it
sufficiently cool down.
If this persist, please lower the ceiling temperature or obstruction to allow the ceiling void to cool down and consult the factory.

Before thermal throttling 100% brightness

After thermal throttling Reduced brightness

For mineral tile grid ceilings, or ceilings with relatively weak or thin constructions, an optional backing strip may be supplied by Innerscene to support the ceiling panel or tile material to allow for field cutting. This is highly recommended when using 2’ x 4’ mineral tiles. One backing strip set is required per fixture. The backing strip stiffens the ceiling tile so it does not crack or crumble during cutting and handling.
If one side of the strip isn’t already roughened, use a coarse sanding block, wire wool, or abrasive sander. Apply a rough texture along an entire one side of the aluminum backing strips — this gives the contact adhesive something to grip onto, since it will not bond reliably to a smooth, polished aluminum surface. Align the strips to form a cut-out with the aid of the notches as a guide.

Clean the back surface of the mineral tile (or similar ceiling medium that requires support) of debris.
Wear a mask, gloves and ventilation masks when working with adhesives. Follow the recommended instruction of your spray-on contact adhesives.
Spray contact adhesives to the coarse face of the backing plate as well as the back of the mineral tile. Wait several minutes (depending on contact adhesive’s manufacturer’s recommendations) for the contact adhesives to dry slightly.

Align the mineral tile with the backing plate. Apply uniform pressure on the two surfaces to adhere them. Start at the centre and work outwards. Allow time for the contact adhesive to cure. Using a drywall knife, cut the inside.

If in doubt, follow instructions for cleaning camera lenses and eyeglasses
Commissioning & Programming
Factory Pre-Commissioning. When ordered with factory pre-commissioning, the local time and geolocation are saved into the primary fixture before shipment. The primary fixture contains a non-rechargeable battery that maintains the clock for around 10 years (or indefinitely if power is maintained).
Programming Codes
The programming code in your spec determines the default behavior:
| Code | Default Behavior |
|---|---|
| P0000 | External Control Only — Fixture responds only to external signals (0-10V, DMX, DALI, or Casambi). No built-in schedule. |
| P0001 | Wall-Clock Schedule (8am–6pm) — Fixture uses a built-in wall-clock schedule when powered on. Time zone based on delivery address; daylight savings handled automatically. Schedule mode is overridden when an external control signal changes. |
| P0002 | Sunrise/Sunset Schedule — Fixture uses a built-in sunrise/sunset schedule based on the latitude and longitude of the delivery address. |
| Custom | Custom programming codes can be created using Innerscene's Programming Tool and pre-loaded before shipping. |
Note: For P0001 and P0002, external dimmer signals are ignored for the first second after power on. After that, an external change overrides the automated schedule.
For instructions on connecting to the fixture, editing the schedule, and managing groups, see the Controller & Studio App page that follows.
Controller & Studio App
Fixture Architecture
★ Primary Fixture
One fixture per installation is the primary. It carries a control daughter board that adds:
- External control inputs (0-10V, DMX, DALI, Casambi)
- Battery-backed real-time clock — keeps accurate time even when powered off
- Time source and group coordinator for secondaries
⬢ Secondary Fixture
All other fixtures in a group are secondaries. They have the full controller built in and can run independently, but in a group they:
- Sync schedule, CCT, and brightness with the primary
- Receive time from the primary's battery-backed clock
- Continue on last known schedule if the primary disconnects
Connecting to Your Fixture
To set the DMX address, edit the schedule, configure groups, or update firmware, connect to the Primary fixture from your phone, tablet, or laptop using one of the methods below.
Method 1 — WiFi Hotspot
Each fixture broadcasts its own WiFi access point. Works from any device with a browser — no app required.
- Open WiFi settings and look for
Innerscene-XXXX(XXXX is unique per fixture). - Connect using password
innerscene. - A captive portal opens automatically. If it doesn't, open
http://172.30.0.1.
Tip: depending on the daughter board, the network may appear as Innerscene-cas-XXXX, Innerscene-0-10V-XXXX, Innerscene-DMX-XXXX, or Innerscene-DT-XXXX — same password and IP.
Method 2 — Innerscene Studio App
Bluetooth LE app for iOS, iPadOS, macOS, Android, and Windows. Discovers nearby fixtures automatically — no WiFi handshake.
- Install Innerscene Studio from your platform's app store.
- Open the app — it scans for nearby fixtures over BLE and lists them with name, group, signal strength, and live status.
- Tap the Primary (marked ★ if part of a group) and authenticate if prompted.
- Use the Home screen sliders, schedule editor, group settings, and firmware updates from inside the app.
Studio reference, screen-by-screen — same app for Circadian Sky and Virtual Sun.
Casambi App Setup & Operation
Innerscene Studio is the preferred way to control fixtures from a phone or tablet. Studio connects directly over Bluetooth to the controller built into every fixture, with no additional hardware, network password, or third-party account required. It is the only app that exposes the full feature set — schedules, circadian automation, real-time clock, multi-fixture group coordination, and the full 2,200 K–200,000 K+ color range. Casambi is provided as an additional pathway, primarily so the fixture can be driven by third-party Casambi-compatible hardware.
When to use Casambi
Casambi adds value when the installation needs to integrate with third-party devices on the Casambi mesh — for example:
- Casambi-compatible wall switches, scene keypads, and rotary dimmers
- Occupancy / presence and daylight (lux) sensors
- Casambi Xpress battery-powered handheld remotes
- Building-management gateways (BACnet, KNX, DALI bridges, HomeKit, etc.)
For everyday hand control of one or many Innerscene fixtures, Studio is faster, simpler, and more capable.
How the two systems interact
Studio and Casambi are independent, peer control sources — not layered. The Casambi module is treated as just another external input, on equal footing with 0-10 V, DMX, or DALI. Studio talks to the fixture's onboard Bluetooth radio directly and does not require Casambi.
- Last command wins. Whichever source — Studio, Casambi, a wall keypad, an external dimmer — most recently sent a level controls the fixture.
- Manual override pauses the schedule. Any manual change from any source switches the fixture out of automated schedule mode until the schedule is re-enabled or the next scheduled transition.
- Scenes are stored separately. Casambi scenes live on the Casambi module; Studio presets and schedules live in the fixture controller. Editing one does not affect the other.
- Casambi is dim + CCT only. Its 2,200 K–8,000 K range is mapped onto the fixture's native 200,000 K+ range, but it has no schedule, astronomical clock, or group coordination — those features are managed from Studio.
- Primary fixture only. Casambi hardware lives in the Primary; secondaries follow the Primary over Innerscene's own coordination link.
