Description
Higher-Power Control for Bigger Setups
The SMS Hybrid Controller Pro (MK2) is built for growers running more or larger fans, delivering up to 8 amps (8A model, 1800 W) or 16 amps (16A model, 3600 W) of controlled output to an intake and an extraction fan from one hybrid controller. As a room scales up, fixed-setting fans and lights waste energy and let temperature and humidity swing more than smaller spaces tolerate; the 8A and 16A models' headroom drives bigger fans, or two at once, while holding the environment steady.
Fixing energy waste and inconsistent conditions in bigger rooms
In larger spaces, running fans and lights on fixed settings rather than responsive control wastes power and lets temperature and humidity drift. The 8A and 16A controllers' higher capacity runs heavier fan loads while keeping conditions consistent.
Key Benefits
- 8A or 16A rated output - up to 1800 W or 3600 W of fan load across the two sockets
- Hybrid technology combining automation with simple manual override
- Energy savings - gear only runs as hard as conditions demand
- Consistent environment across bigger grow spaces
- Single-point control of intake and extraction, with a light sensor that switches to a night-time humidity routine when the lamps go off
How to Use
- Plug your extraction and intake fans into the controller's two sockets - no wiring needed - and place the 5 m probe in the canopy
- Keep total load within the 8A or 16A rating of your model
- Set the minimum and maximum fan speed and the target temperature on the three dials and let the controller adjust automatically; leave the light sensor uncovered to run the night-time humidity routine, or fit its rubber cap to switch that off
- Review settings as the room's plant load or growth stage changes

Frequently Asked Questions
Which size do I need, 8A or 16A?
Add up the rated load of the fans you will plug in and pick the model with headroom: the 8A handles up to 1800 W across both sockets and the 16A up to 3600 W. The 16A is for large high-wattage fans, or a big extraction and intake pair run together.
Can I run just one fan from it?
Yes. It works with a single extraction fan; the second socket is for an intake fan, which is usually set a little weaker than the extraction so the room stays under slight negative pressure.
Why doesn't it hum at low speeds like other controllers?
Speed is changed in five mechanical steps through a transformer rather than by pulsing the power as many electronic controllers do, so fans stay quiet at every setting. The digital side reads the 5 m probe and chooses the step.
Does it control humidity?
There is no humidity set-point. With the light sensor uncovered it detects lights-off and steps the fans up one speed for about 5 minutes each hour to clear damp air; fit the supplied rubber cap over the sensor to switch that routine off.
