Dimlux Fan Aux Box 15A – Fan Speed Controller

Hand Your Fan, Heater and Humidity Control to the Maxi Controller

The Dimlux Fan Aux Box is the add-on that lets a Dimlux Maxi Controller EVO run the rest of the grow room, not just the lights. It connects to the controller's Aux/Fan output and gives you three UK sockets, each rated at 15A, marked for the extractor fan, a humidifier or dehumidifier and a heater. From then on temperature and humidity are handled from the same screen that already manages lighting and CO2.

Key Benefits

• Three 15A outputs – fan, RH (humidifier or dehumidifier) and heater from one box
• Electronic fan speed control – quiet in use, without the hum of a transformer-type controller
• SmartLogic temperature control – adjusts fan speed so the room settles on the set temperature rather than swinging around it
• Separate day and night RH settings – humidity targets for lights-on and lights-off, each adjustable
• One control point – climate and lighting set from the Maxi Controller, with no stand-alone thermostats to reconcile

Why Separate Controllers Fight Each Other

A grow room run on a standalone fan speed controller, a plug-in humidistat and a heater thermostat often has three devices pulling against each other: the fan dumps warm air the heater has just made, or the dehumidifier runs flat out while extraction does the same job. The result is temperature and humidity swings, wasted power and stress on the plants at the moments when stable conditions matter most. Putting fan, heating and humidity equipment on one controller that knows the light schedule keeps them working together, day and night.

How to Use

• Connect the box to the Aux/Fan port of a Dimlux Maxi Controller EVO
• Plug the extractor fan, humidifier or dehumidifier and heater into their marked sockets
• Set day and night temperature and RH targets on the Maxi Controller
• Keep the total load on each socket within its 15A rating
