Installation Overview
Control system installation — low-voltage signal wiring; typically DIY-friendly. Consult the included manual for model-specific diagrams.
- Power down the steam generator at the breaker before working with any wiring.
- Mount the control unit at the desired wall location (typically inside or adjacent to the steam room, at accessible height).
- Route the signal cable from the control to the generator junction box — keep away from high-voltage wiring.
- Connect the wires to the labeled terminals on both the control and the generator (typically color-coded or numbered).
- Secure all cable runs with clips or conduit as required by local code.
- Restore power and follow the pairing/commissioning sequence in the manual.
- Test all functions: heat, timer, aromatherapy (if equipped), and indicator lights.
Compatibility & System Requirements
This part is designed for use with:
- Spa Parts Products
Control compatibility: Steam generators have a specific control protocol. Mix-and-match between brands is not supported. Verify the exact control family (e.g., AirTempo vs. iSteamX) matches your generator.

Frequently Asked Questions
Will this control work with my existing generator?
Controls are brand- and family-specific. An AirTempo control only works with AirTempo-compatible Mr.Steam generators; an iSteamX control requires an iSteamX-compatible unit. Verify your generator's model number against the compatibility list before ordering.
Can I install this control myself?
Most control installations involve low-voltage signal wiring only, which is generally considered DIY-friendly. However, if any line-voltage wiring must be moved or reconnected, a licensed electrician is required. Consult the enclosed installation manual.
What if my new control doesn't pair with the generator?
Follow the commissioning sequence in the manual exactly — it usually involves holding a button on the generator PCB while powering on the control. If pairing fails, confirm the firmware is compatible or contact the manufacturer's technical support.
