Cyclone Digital Controller for EC Extractor – Automatic Temperature and Humidity Control
A fixed-speed extractor is always poorly adjusted: during the day it falls short, and at night it extracts too much, pulling out heat and humidity the plant needs. This controller connects directly to the Cyclone EC extractor and regulates its speed based on what its temperature and humidity probe reads, increasing when the grow tent heats up and lowering when it is already at the right point.
Key features
- Setpoint control: you set the target temperature and humidity and the unit does the rest.
- Variable speed: it takes advantage of the EC motor instead of just switching on and off.
- Included probe: measures temperature and humidity at the point where you place it.
- Digital display: value and setpoint readings at a glance.
- Direct connection: plugs into the Cyclone extractor control cable, with no adapters.
Why variable speed matters
A simple on/off controller turns the extractor off when it reaches the setpoint, and with it air renewal and odor filtering stop too. By regulating speed, the extractor never stops completely: it maintains negative pressure in the grow tent and odor under control while adjusting airflow to the actual thermal load.
Installation
- Probe: place it at canopy height, away from the light and from the direct airflow of the intake fan.
- Setpoints: start at 25-26 °C and 55-60% relative humidity and adjust according to the stage.
- Minimum: always leave a minimum speed that maintains negative pressure in the grow tent.
Compatible with the EC Cyclone extractor with built-in carbon filter.

2. Coloca la sonda a la altura de las copas, lejos del foco y del intractor.
3. Conecta el cable de control al conector del extractor EC Cyclone.
4. Enchufa el controlador a la corriente y comprueba que el extractor responde.
5. Fija las consignas: empieza en 25-26 °C y 55-60 % de humedad relativa.
6. Ajusta la velocidad mínima para que el armario mantenga siempre algo de depresión.

Frequently asked questions
-
It is a controller that regulates the speed of the EC Cyclone extractor fan based on the temperature and humidity read by its probe. It raises airflow when the tent heats up and lowers it once conditions are right, avoiding the mismatch typical of a fixed-speed extractor fan. Everything is visible at a glance on its digital display.
-
You set the target temperature and humidity and the unit does the rest. The controller compares those setpoints with what the probe measures and adjusts the extractor fan speed automatically. That way the tent stays stable without you having to touch anything.
-
An on-off controller switches the extractor fan off when the setpoint is reached, and with it both air renewal and odour filtering stop. This unit regulates the speed variably, so the extractor fan never stops completely: it keeps negative pressure in the tent and the smell under control while matching airflow to the real heat load.
-
Yes, it includes a probe that measures temperature and humidity at the point where you place it. The recommendation is to put it at the height of the plant tops, away from the lamp and out of the intake fan's direct draught. That way the readings reflect the real environment your plants are breathing.
-
It is designed to connect directly to the control cable of the EC Cyclone extractor fan, with no adapters. It is compatible with the EC Cyclone extractor fan with built-in carbon filter, making use of its EC motor to regulate speed instead of just switching on and off.
-
A good starting point is to set 25-26 degrees of temperature and 55-60 per cent relative humidity, then adjust according to the stage of the grow. Remember to always leave a minimum speed that keeps negative pressure in the tent so air and smell stay under control.
