Product description
SMSCOM Twin Controller MK2 -7A: measuring, monitoring and adjusting
The SMSCOM Twin Controller 7A is a high-quality dual fan controller that controls two fans independently to ensure a constant temperature and stable negative pressure in the grow room. The unit runs almost silently, prevents temperature fluctuations and keeps the climate perfectly balanced.
The external temperature sensor constantly measures the environment and adjusts fan output automatically. This makes the 7A controller ideal for small to medium-sized grow tents and grow rooms that need maximum climate stability.
Why the SMSCOM Twin Controller 7A?
Automatic temperature control
Fan output adjusts itself to the measured temperature.
Stable negative pressure
Ideal for carbon filters – prevents odours escaping.
Two separate fan outputs
Independent control of intake and extraction (up to 7A total load).
Very quiet operation
No jerks or noise peaks, thanks to stepless control.
Plug-&-play installation
Just connect, set the values, done.
Product description / product details
Effect & properties
The Twin Controller ensures even temperatures and protects plants from heat or cold stress. At the same time, it maintains controlled negative pressure, which is particularly important when carbon filters are in use.
The controller works steplessly, preventing jerky fan movements. The precise sensor delivers accurate readings and enables smooth adjustment of fan speed – ideal for calm, stable growing conditions.
Suitable growing systems
Ideal for:
Small & mid-size grow tents (80×80 to 150×150 cm)
Indoor grow rooms
Extraction systems with carbon filter
AC inline fans & box fans
Temperature-critical crops
Use / installation
Connect two fans (intake & extraction)
Place the temperature sensor in the room (not directly under the light)
