Product description
SMSCOM Twin Controller MK2 -4.5A: measuring, monitoring and adjusting
The Twin Controller 4.5A was developed to give growers reliable, automatic control over their grow room climate. The integrated sensor constantly measures the temperature and regulates both the intake and extraction fans to maintain the set target value.
The controller keeps the negative pressure in the grow room constant – crucial for effective odour control. Stepless speed control significantly reduces fan noise and ensures energy-efficient operation.
Key benefits of the SMSCOM Twin Controller 4.5A
Dual-channel control for intake and extraction
4.5 A total capacity – ideal for small & medium fans
Automatic temperature control with precise sensor
Constant negative pressure for maximum odour control

Product description / product details
Effect & properties
The Twin Controller monitors the temperature and automatically adjusts the speed of both fans. The climate stays stable – no overheating, no big fluctuations.
Controlled air movement improves CO₂ availability, prevents humidity problems and optimises photosynthesis. Because intake and extraction work in sync, negative pressure stays constant, effectively preventing odour problems.
