Control system installation — low-voltage signal wiring; typically DIY-friendly. Consult the included manual for model-specific diagrams.

1. Power down the steam generator at the breaker before working with any wiring.
2. Mount the control unit at the desired wall location (typically inside or adjacent to the steam room, at accessible height).
3. Route the signal cable from the control to the generator junction box — keep away from high-voltage wiring.
4. Connect the wires to the labeled terminals on both the control and the generator (typically color-coded or numbered).
5. Secure all cable runs with clips or conduit as required by local code.
6. Restore power and follow the pairing/commissioning sequence in the manual.
7. Test all functions: heat, timer, aromatherapy (if equipped), and indicator lights.
