Wiring Reference
Load ratings, wiring diagrams, and compatibility notes for Smartify switches, retrofit relays, dimmers, LED controllers, and shutter modules.
All TAC smart switches and retrofit relays work without a neutral wire — Live and Load only. TOQ panels require neutral.
Load Ratings
| Device | Rating | Notes |
|---|---|---|
| TAC standard switch (1–6G) | 10A / 2300W per channel | Shared L input, separate output per gang |
| TAC HL heavy-load switch | 16A / 3680W | Pumps, geysers, high-draw loads |
| TAC F fan switch | 1A / 230W | Fan speed control only |
| Retrofit relay 1Ch (standard) | 4A | Behind existing switch, no rewiring |
| Retrofit relay 1Ch (heavy) | 40A | Pumps, geysers, HVAC compressors |
| Retrofit relay 2Ch | 4A per channel | 2 independent circuits, 1 module |
| Retrofit dimmer 1Ch | 200W resistive / 100W LED | Phase-cut — dimmable loads only |
| 0–10V dimmer | — | Commercial LED drivers with 0–10V input |
| Shutter module | 5A / 1150W | AC motors with end-stop protection only |
| TAC SH shutter switch | 5A | Premium wall-switch shutter control |
TAC Smart Switches
No neutral required. Each gang has its own output terminal; all share a single L input.
Retrofit Relay
Installs behind the existing wall switch — no rewiring, no new backbox. The existing switch toggles locally; Zigbee overrides it remotely.
Standard (4A) — lighting, fans, general loads. Heavy-duty (40A) — pumps, geysers, AC compressors, high-inrush motors.
Retrofit Dimmer
Phase-cut dimming only. Not compatible with non-dimmable LED drivers, fluorescent fixtures, or motors.
- Minimum load: 5W
- Maximum load: 200W resistive / 100W dimmable LED
- Dimmable LED drivers must be explicitly rated for phase-cut dimming
0–10V Dimmer
For commercial LED drivers with a 0–10V control input (common in offices, retail, hospitality).
LED Controllers
CV-RGB+CCT (Constant Voltage)
For 12V or 24V LED strip lights. Controls RGB colour + warm/cool colour temperature simultaneously.
CC-CCT (Constant Current)
For current-fed LED fixtures and commercial downlights (350 mA / 500 mA / 700 mA).
Shutter / Blind Module
AC motors only. Motor must have built-in end-stop protection — do not use with motors lacking end-stops.
The module detects end-stop via current sensing. Configure travel time in the Zigbee coordinator after installation.
TOQ Touch Panels
TOQ panels replace the existing switch backbox. They require a neutral wire in addition to Live.
Available in 1-gang, 2-gang, and 3-gang backbox form factors.
