Vortex Twin Speed Thermostatic Fan Speed Controller

The Vortex Twin Speed Thermostatic Fan Speed Controller provides complete, automated climate management for your grow room or tent setup. Designed to control both fresh air intake and stale air extraction fans simultaneously, this intelligent unit constantly adjusts fan speeds based on real-time temperature readings to maintain your target growing environment effortlessly.

Featuring two independent power outlets (one intake, one exhaust), the controller accommodates fans up to a maximum load of 320 Watts (1.4 Amps) per socket. Built-in precision controls allow growers to set a target grow room temperature between 5°C and 45°C, monitored continuously via a remote temperature sensor probe. The target temperature is clearly shown on the integrated numerical digital display, backed by an active LED indicator light that confirms when climate parameters are being actively maintained.

To prevent fan motor hum and maintain proper air quality when the room drops below your set target, the Idle Speed Control lets you lock in a continuous minimum baseline speed between 20% and 60%. Meanwhile, the Balance Control dial lets you adjust the speed differential between intake and exhaust fans. This ensures you maintain negative air pressure at all times—preventing untreated odours, humidity, and heat from escaping into surrounding living spaces.

Equipped with a detachable IEC main power cable and an easily accessible reset circuit breaker, the controller protects internal electronics against power surges and electrical overloads without requiring fuse replacements.

Pro-Tip: Set your Balance Control so your intake fan runs slightly slower than your exhaust fan. You can confirm negative air pressure is achieved when your grow tent walls bow slightly inwards, guaranteeing all air escapes through your carbon filter.

Key Benefits:

• Dual Fan Control: Independent power outlets for intake and extraction fans (up to 320W / 1.4A per socket).

• Automated Temperature Regulation: Monitors room temperature via a dedicated sensor probe and ramps fan speeds up or down automatically.

• Negative Pressure Balance: Precision balance dial adjusts intake/exhaust differential to prevent odour leaks.

• Variable Idle Speed (20%–60%): Ensures fans never turn off completely, keeping fresh air moving and preventing dampness when temperatures fall.

• Clear Digital Interface: Bright numerical display shows target temperature settings (5°C–45°C) with an LED status indicator.

• Built-in Overload Protection: Resettable circuit breaker protects your fans and controller from power surges without needing replacement fuses.
