Control Freak Dynamic Frequency Fan Speed Controller

Silent Fan Speed Control with No Hum

The Control Freak Dynamic Frequency Fan Controller varies fan speed using up-to-date digital temperature sensing, silently. It runs any AC fan without the humming and buzzing that cheaper controllers produce, which is the difference between a room you can sit next to and one you can hear from the hallway. Set an optimal temperature range plus a minimum and maximum fan speed and it works between them automatically, or drive it manually. It comes in 3A, 7A and 13A versions, suiting everything from a single tent to a large facility.

Key Benefits

• Completely silent operation with zero humming from your extractors
• Highly accurate temperature control rather than crude voltage throttling
• Automatic and manual modes, with your own temperature range and speed limits
• Sensor on 5m of cable, long enough to sit at canopy height
• Three ratings – 3A (1.5A per socket), 7A (3.5A per socket) and 13A (6.5A per socket)
• Runs any AC fan, so it suits the extraction you already own

Noisy Extraction and a Room That Swings

A fan on full all day wastes the heat you paid for; leave it slow and temperature climbs while airflow goes stale, which is when humidity, mildew and airy buds show up. Basic controllers chop the waveform, so the fan hums and the room never settles. Dynamic frequency control adjusts speed smoothly against an accurate reading, holding the room in range without the noise.

How to Use

• Set up in line with the manufacturer’s instruction manual supplied with the unit
• Choose the right amperage – 3A, 7A or 13A total, at 1.5A, 3.5A or 6.5A per socket
• Place the sensor at canopy height on the 5m cable, away from light and duct outlets
• Set your temperature range plus minimum and maximum fan speed, then leave it in automatic
• Always run an intake fan alongside it to maintain negative pressure
