Pro-Leaf BECC-B2 Multi-Function Environmental Controller

One controller for CO2, temperature, humidity and day/night switching

The Pro-Leaf BECC-B2 is a multi-function environmental controller that takes over the job of running a grow room's climate equipment from four separate 240V switched outlets, so cooling, heating, humidity and CO2 devices can all be triggered from a single unit rather than a shelf of individual thermostats and timers. It sits apart from Pro-Leaf's dedicated CO2-only controllers by covering the whole environment in one box.

CO2 is monitored and held within a 400-2000ppm range with an adjustable deadband, and the controller uses fuzzy-logic control to keep dosing accurate even in tightly sealed rooms running compressed CO2. Temperature is regulated across a 5-50°C range and relative humidity across 5-95%, both with their own adjustable deadbands, so heaters, coolers, extraction and humidifiers or dehumidifiers can all be told to switch in only when actually needed. A remote sensor on a 4.5m cable carries an integrated photocell, which lets the BECC-B2 apply separate day and night temperature and humidity targets automatically as the lights cycle, rather than needing the grower to reset targets by hand.

This makes it suited to growers running a full tent or room where CO2 enrichment, climate control and light-cycle-aware switching all need to work together rather than being handled by separate, uncoordinated devices.

• Four 240V outlets - drive cooling, heating, humidity and CO2 equipment from one controller
• Wide CO2 range - 400-2000ppm with adjustable deadband and fuzzy-logic dosing accuracy
• Full climate control - temperature held across 5-50°C, humidity across 5-95% RH
• Day/night aware - integrated photocell on the remote sensor applies separate day and night targets automatically
• Remote sensing - 4.5m sensor cable keeps the sensing point away from the controller itself
