TEMPOBOX 12 x 600 W Timer with Heater Socket is a multi-base box designed to coordinate large blocks of light in indoor cultivation and stabilize the climate thanks to an auxiliary socket for heater. Analog programming of 15 minutes, 48 h power reserve and easy integration into indoor cultivation installations.

The TBOX 12H model is designed for large-format rooms and cabinets where photoperiod synchronization and thermal control make the difference.
This unit manages configurations of 12 x 600 W, 12 x 630 W, 16 x 400 W, or 20 x 315 W, distributing the load by lines with maximum power 2,520 W per line.
In addition, it incorporates a 2,400 W heater socket to maintain a stable temperature during periods without light, a key piece in cannabis cultivation when seeking to avoid sharp nighttime drops.
The analog timer with minimum steps of 15 minutes makes it easy to set 18/6 or 12/12 precisely, and the 48 h power reserve maintains programming in the event of brief power outages.
The unit operates at 230 Vac / 50 Hz, with a compact chassis of 241 x 180 x 95 mm and IP20 protection, ideal for technical panels, racks, or walls near the control panel.
Integrated with grow controllers (thermostats, hygrostats, CO₂) and indoor electrical accessories (contactors, circuit breakers, residual current devices), it creates an organized ecosystem that provides operational safety, uniform PPFD, clean transition to flowering, and better planning of irrigation, pruning, and maintenance tasks around cannabis plants.
This multi-base box, thanks to the auxiliary socket, allows the light cycle to be accompanied by thermal input when needed, stabilizing relative humidity and preventing condensation during the dark phase.
In environments where multiple rows of lights operate, the TEMPOBOX Timer 12 x 600 W With Heater Socket ensures uniform switching and more predictable climate control. Coordinated switching reduces current spikes and smooths thermal variations; the auxiliary socket for the heater helps maintain the microclimate within optimal ranges when the canopy is in darkness, key for vigor and health in indoor cultivation.
It is used to automate the switching on/off of up to 12 luminaires of 600 W (and other indicated combinations) with 15-minute steps and, in addition, to power a dedicated heater (2,400 W) that helps stabilize the environment during periods without light. This duality makes the unit the operational core of indoor cultivation installations that require photoperiod consistency and fine-tuned thermal control.
As a central tool in the panel, it centralizes twelve outputs and organizes wiring, streamlining audits and maintenance. It operates at 230 Vac / 50 Hz, with maximum power 2,520 W per line, auxiliary socket 2,400 W, and IP20 protection. The 241 x 180 x 95 mm format fits into panels with other grow controllers and indoor electrical accessories, allowing scalability without losing cleanliness or traceability.
1) Fix the chassis on a firm and ventilated surface, respecting IP20 and keeping away from splashes.
2) Connect power supply to 230 Vac / 50 Hz with properly rated circuit breaker and residual current protection.
3) Distribute lights by lines respecting 2,520 W per line and the recommended cable section.
4) Program the analog timer in 15-minute steps for growth (18/6) or flowering (12/12).
5) Connect the heater to the auxiliary socket 2,400 W and adjust the thermostat of the equipment itself to maintain the target temperature during the dark phase.
6) Label lines and document schedules for quick diagnostics and traceability.
7) Verify 24 h of operation to confirm switching and thermal stability.
The investment is offset by the reduction of loose modules, less setup time, and fewer incidents due to time or thermal mismatches. Check promotions and packs at Hydroponics Blanes, trusted Grow Shop with a specialized catalog in grow controllers and indoor electrical accessories.
