The Control Freak Intelligent Fan Controller could not be easier to use, with its ’Plug & Play’ design and two modes of operation. You can use it as a manual fan speed controller or use an additional 5m temperature probe to operate the unit as a fully automatic speed controller. The probe allows you to use a bespoke software system and gives 50 different speed settings to maintain your grow room. This controller has smooth speed control, giving a more accurate and a quieter operation. The temperature adjustment when using the probe his highly accurate with an adjustment of +/- 1°C. Directions of use: Without temperature probe:

• Plug the fan into the controller and set the minimum fan speed.
• Plug the controller in a socket and turn on.

With temperature probe:

• Plug the fan into the controller and set the minimum fan speed.
• Plug the temperature probe into the controller and set desired room temperature.
• Place the sensor in the centre of the grow room – never in direct airflow of the fan.
• Plug the controller into a socket and turn on.

When switched on, the controller and sensor will scan the room. Once complete, the fan will run at the required speed to maintain grow room temperatures, adjusting when necessary.
