Description
Switch Every Light in the Room From One Timer, Safely
The Timer Box Pro is a contactor timer for grow rooms: a steel box with a built-in 24-hour segment timer, a heavy-duty contactor and a row of switched UK sockets, plus a separate labelled heater socket. The timer drives the contactor, and the contactor carries the load, so several grow light ballasts come on and off together without overloading an ordinary plug-in timer. Choose 4 Way, 6 Way or 8 Way to suit the size of your room.
Key Benefits
- Contactor switching - the timer only operates the contactor, so it is not burnt out by the start-up draw of HID ballasts.
- All lights in sync - every light socket switches at exactly the same moment.
- Individually switched sockets - turn one light off without touching the rest.
- Dedicated heater socket - a clearly labelled outlet for a grow room heater.
- All-metal case with a hanging bracket for wall or frame mounting.
- Load guide: 4 Way up to 4 x 600W or 3 x 1000W; 6 Way up to 6 x 600W or 4 x 1000W; 8 Way up to 8 x 600W or 4 x 1000W.
Why Not Just Use a Plug-In Timer?
A household timer is rated for a lamp, not a bank of grow light ballasts. The inrush when several lights strike at once can weld its contacts, leaving lights stuck on or off and upsetting the photoperiod. A contactor timer puts that load on a switch built for it.
How to Use
- Hang the box on a wall or frame, away from water, using the bracket.
- Plug each ballast or LED driver into a switched socket and keep the total within the load guide above.
- Plug the heater into the socket marked HEATER.
- Set the on and off times by pushing in the timer segments, then plug the Timer Box into the mains.
