CG Air Electronic Variable Speed TMS Control [IC-TMSV-120/60-020-N-N] For Air Blower or Pump

IC-TMSV-120/60-020-N-N is a compact, electronic TMS control designed to power and regulate both air blowers and variable-speed pumps in basic spa, hydrotherapy, and small-scale drying or ventillation setups. Built for reliability, this control box brings precise speed management and a streamlined wiring setup to keep systems running smoothly.

Key capabilities that set it apart

• Variable-speed blower control—whether you need a quiet, low-profile air flow or a stronger blast, this unit supports blower operation at adjustable speeds for consistent performance and reduced noise.
• Variable-speed pump control—tailor pump performance to match the job, optimizing flow, efficiency, and system response.
• 3-button keypad interface—intuitive, on-box control for quick speed adjustments and straightforward setup.
• 120V / 60Hz electrical supply—designed to integrate with standard outlets and wiring found in most shops, basements, and mechanical rooms.
• NEMA connectors—clear, dependable power connections: the blower uses a NEMA female receptacle, while the power supply plugs in with a NEMA male connector for safe, plug-and-play installation.
• Automatic purge sequence—after system shutdown, the unit automatically enters a 20-minute purge, then restarts briefly (about 1 minute) to purge jets and plumbing lines, helping keep lines clear and ready for the next run.

How it works in real-world use

In spa, hot tub, or hydrotherapy installations, the IC-TMSV-120/60-020-N-N serves as the central brain for both the air delivery and water- or hydrojet-pump subsystems. Set your desired blower and pump speeds via the keypad, and enjoy stable, responsive performance without needing separate controllers for each component. When the cycle ends, you don’t have to worry about stale lines—the built-in automatic purge flushes the system to clear jets and plumbing, reducing mineral buildup and odors over time.

Ideal for

• Residential spas and hot tubs requiring reliable, adjustable air and pump control
• Small commercial hydrotherapy stations where consistent purge cycles improve hygiene and readiness
• DIY hydro systems and wellness installations that benefit from a single, integrated control box

Installation and compatibility

The IC-TMSV-120/60-020-N-N is designed for straightforward integration with 120V, 60Hz systems. It provides a dedicated blower receptacle and a separate power supply plug, simplifying wiring runs and reducing installation time. The three-button keypad gives operators quick access to speed adjustments, while the variable-speed capabilities enable fine-tuned performance across a range of system sizes and requirements.
