The BTCL-B2, digital lighting and recycle timer, features dual timer functionality, separately controlling a recycle timer and 24-hour lighting time clock. Its four receptacles power two lights up to 600 watts each ( or alternatively coordinate a 600 watt light and light-mover), a recycling device (such as H2O pump, reservoir chiller/heater, etc.) and a night-only device. Integrated safety features with a remote sensor on a 4.5-meter cable accurately monitors garden temperatures, triggering light deactivation at an adjustable temperature set point in the event of ventilation failure.
