Timer Box III (12x600W) + Three-phase Heater coordinates up to 12 lamps of 600 W with simultaneous on/off and activates a heater in night mode. Compact solution for indoor cultivation that provides lighting and thermal stability in indoor cultivation installations.

The GSE timer is designed to handle inductive loads typical of HPS/MH lamps or LED equipment with ballast/driver, ensuring precise photoperiods and controlled climate in technical rooms.
Timer Box III (12x600W) + Three-phase Heater integrates 12 outputs of 600 W for lighting and a dedicated heater socket (up to 2400 W in resistive loads) that activates automatically when the lamps turn off, maintaining the nighttime temperature of the room.
The simultaneous control of the lights eliminates mismatches between rows and ensures uniform PPFD; the 24 h mechanical programming with 15-minute steps simplifies quick adjustments for 18/6 growth or 12/12 flowering. The unit operates at 230 V, with 33 A nominal, and a relay with mechanical resistance of 10,000,000 cycles, designed for intensive use.
The set is housed in a sealed enclosure with IP54 protection class, suitable against dust and splashes common in the cultivation environment.
It incorporates a backup battery to keep the clock running during brief outages, preserving the schedule.
Approximate dimensions 50 × 16 × 11.5 mm (control module format indicated by the manufacturer). Designed to integrate with grow controllers (thermostats, hygrostats, CO₂) and other indoor electrical accessories (circuit breakers, residual-current devices, contactors), creating an organized and traceable electrical core.
For those seeking consistent performance in cannabis cultivation, this box reduces human error, stabilizes temperature and humidity at night, and facilitates scheduled maintenance.

Programming twelve lights at once allows for a homogeneous canopy and clear planning of irrigation, pruning, and air changes. The night mode with heater socket prevents sharp thermal drops, reduces condensation, and stabilizes the metabolism of cannabis plants in indoor cultivation.
It is used to automate the photoperiod of 12 × 600 W with joint switching and to activate a heater of up to 2400 W when the light turns off. Objective: regular cycles, stable climate, and maximum operational repeatability in indoor cultivation installations aimed at performance.
As a core tool of the electrical panel, it centralizes outputs, organizes bundles, and facilitates audits. Highlighted specifications: 230 V · 33 A · 12 × 600 W lighting · 2400 W heater resistive · 24 h timer with 15 min per step · IP54 · relay up to 10,000,000 cycles · clock backup. A reliable set for panels with grow controllers and indoor electrical accessories.
1) Anchor the box on a firm and ventilated surface, respecting IP54 and avoiding splash zones.
2) Connect power to 230 V and size protections (circuit breaker/residual-current device) to the required amperage.
3) Distribute up to 12 luminaires of 600 W in the outputs, considering contactors when the inrush current advises it.
4) Program the 24 h mechanical timer in 15-minute blocks for 18/6 or 12/12.
5) Connect heater to the dedicated socket (max. 2400 W resistive); night mode will activate heating when the light turns off.
6) Label lines and organize cables for quick diagnostics and preventive maintenance.
7) Verify 24 h of operation: switchings, nighttime temperature, and clock autonomy in case of micro-outages.
The cost is offset by less installation complexity, fewer manual errors, and a stable nighttime climate. Check packs and offers at Hydroponics Blanes, trusted Grow Shop with a catalog of grow controllers and indoor electrical accessories adapted to each project.
