What is the Time-R Digital Timer used for?
Time-R Digital Timer gives you precise control over grow room gear like lights, pumps, CO₂, fans, humidifiers, and UVB/UVA lighting. It’s programmable down to 1-second switching and supports advanced routines like pulsing and interval dosing—making it more flexible than basic timers.
What modes does the Time-R Digital Timer have?
There are three: Timed Mode (set ON/OFF times), Repeat Mode (set repeating intervals), and Combined Mode (run repeating cycles inside a set daily window). These cover everything from light schedules to short irrigation pulses.
Can I set a normal grow light schedule like 18/6 or 12/12?
Yes—use Timed Mode to set start and end times for your light cycle. You can program up to 15 ON/OFF events per day for more complex lighting needs.
How does Repeat Mode work?
Repeat Mode turns gear on and off at fixed intervals—perfect for pumps or CO₂ solenoids. You can set ON times as short as 1 second and OFF times up to 99 hours, running in a continuous loop.
What is Combined Mode used for?
Combined Mode lets you run repeating cycles only during certain hours—like pulsing a fan or humidifier during lights-on only. It supports up to 3 daily “group” windows, giving you full control over timing.
How much power can the Time-R Digital Timer handle?
Always check the rating printed on the unit. Most timers in this category support around 10–13A. You can use a powerboard for multiple devices if the total load stays well under the timer and board limits.
Does the Time-R Digital Timer save settings during a power outage?
Yes—it has an internal rechargeable battery that stores your programs and clock. For best results, charge it for at least 2 hours before first use. After long outages, double-check the time and settings.
How do I set the clock or change time format?
Hold the clock button until it flashes, then use the arrow keys to set the time. To switch between 12-hour and 24-hour formats, press and hold the confirm button and choose the format shown on screen.
Does it have a backlit screen?
Yes—it has a large, green backlit screen that’s easy to read. The green light is designed to be less disruptive in flowering environments, especially when used briefly during checks.
Can I manually override the timer or lock the settings?
You can manually switch modes, but it's best to use the programmed settings to avoid breaking cycles. After programming, lock the timer (press confirm 3×) to prevent accidental button presses.
Why isn’t my Time-R Digital Timer switching on or off correctly?
Common issues include the wrong clock setting (especially AM/PM), being in the wrong mode, or changes after a power cut. Reset the time, review your program, and make sure the device is locked into the correct mode.
Why is the display blank or unresponsive?
Check if the wall socket has power and try another outlet. If it’s still blank, the internal battery may need charging. Leave it plugged in for a few hours, then reset and reprogram if needed.
Can I use the Time-R Digital Timer inside a grow tent?
It’s best to keep it outside the tent or mounted high and dry. Avoid splash zones, runoff trays, and condensation. As with all electrical gear, keep cables elevated and use drip loops.
Can I use Time-R Digital Timer to control a contactor or relay?
Yes—this is the recommended approach for large setups. Use Time-R to switch the contactor, which then safely handles the heavier load for HID lights or multiple drivers.
Why do growers like the Time-R Digital Timer?
It’s popular for its large screen, intuitive interface, and flexible scheduling. With Timed, Repeat, and Combined Modes, it handles everything from standard lighting cycles to short UV bursts and irrigation pulses.
