Manual control vs. automatic temperature regulation
The Speed Controller is the right choice when you need a fixed ventilation rate that doesn't change with temperature fluctuations — for example, in sealed grow tents with CO₂ enrichment, or as a supplement to an existing climate system. If automatic temperature-based fan control is required, the Cli-Mate Temp Controller or the Cli-Mate Fan Controller offer 2-step automated switching based on a remote temperature sensor.
Installation and compatibility
Setup is straightforward: connect the Speed Controller between the mains socket and your fan or extractor, then dial in the target speed. Its compact housing (55 × 40 × 135 mm) fits easily in tight spaces such as grow tents, cabinets, or utility rooms. The SPC series is compatible with all standard AC motor fans and inline extractors rated at or below 4A, including setups paired with carbon filters for odour control. For a fully integrated all-in-one solution covering temperature, humidity, and lighting, consider the Cli-Mate Mini-Controller.

Does the Cli-Mate Speed Controller include a temperature sensor?
No. The Speed Controller is a purely manual dimmer with no sensor or automatic switching. Fan speed is set manually via the rotary knob and remains constant until adjusted. For automatic temperature-based fan control, choose the Cli-Mate Fan Controller or Temp Controller instead.
What is the maximum amperage of the Cli-Mate Speed Controller?
The Speed Controller supports a maximum load of 4 amps on a 1-phase 220/230V – 50Hz supply. Always verify the rated current of your fan or extractor before connecting. Do not exceed the 4A limit to avoid overloading the controller.
Can I use the Speed Controller with a carbon filter setup?
Yes, as long as the connected fan does not exceed 4A. Reducing fan speed lowers the airflow through the carbon filter proportionally. This is a common approach when full extraction capacity is not needed at all times, helping to extend filter lifespan.
Is the Cli-Mate Speed Controller compatible with EC fans?
No. The Speed Controller is designed for standard AC motor fans only. EC (electronically commutated) fans require dedicated EC controllers and are not compatible with this dimmer. Check your fan's motor type before purchasing.
