Why Choose the Titan Controls Apollo 11

The Apollo 11 addresses a common gap in indoor grow room setups: the need for programmable, digital timer control at 240 volts. Most consumer-grade plug-in timers operate at 120 V. The Apollo 11 is built for the 240 V circuit that high-draw grow equipment often requires, and its digital programming removes the mechanical imprecision of a rotating dial timer.

• True 240 V digital control. The Apollo 11 is rated for 240 V / 60 Hz operation. This makes it compatible with 240 V HID lighting systems, large irrigation pumps, and other grow room equipment that requires a 240-volt circuit. Growers running 240 V equipment need a timer that can operate safely at that voltage—the Apollo 11 is purpose-built for exactly that application.
• 1-minute scheduling granularity with up to 20 programs. Digital timers allow exact on/off times down to the minute. The Apollo 11 supports up to 20 separate schedules per day, which provides enough flexibility for complex lighting or irrigation routines that change throughout the photoperiod without being constrained by mechanical peg spacing.
• Battery backup protects programmed schedules. When main power is interrupted—whether from a tripped breaker, a momentary power outage, or scheduled electrical work—the Apollo 11’s battery backup feature retains all programmed on/off schedules. Without this feature, a power interruption would require manual reprogramming of every schedule; the battery backup prevents that disruption.
• Daylight savings mode eliminates manual clock adjustment. Growers running light-sensitive crops on fixed photoperiod schedules need their timers to stay accurate through daylight savings time changes. The Apollo 11 includes a daylight savings mode that accommodates the time change automatically, keeping programmed schedules consistent without manual adjustment each spring and fall.
• Heavy-duty enclosure built for grow room conditions. Indoor growing environments involve elevated humidity, water vapor, and airborne particulates. The Apollo 11’s enclosure is designed to resist dust, rust, and moisture—conditions that degrade standard electrical equipment over time. This makes it more appropriate for long-term use in active grow spaces than a standard household timer.

Best Uses for the Titan Controls Apollo 11

The Apollo 11 is a single-outlet digital timer for 240 V applications. Its best uses are scenarios where a grower needs reliable, programmable automated control of a single high-voltage device in a grow room, greenhouse, or similar controlled environment.

• HID grow light scheduling. High-intensity discharge (HID) lighting systems—including high-pressure sodium (HPS) and metal halide (MH) fixtures—commonly operate at 240 V. The Apollo 11 can control when these lights power on and off, maintaining a consistent photoperiod for light-sensitive crops. Pair the Apollo 11 with an advanced lighting controller like the Autopilot PX2 advanced lighting controller for full dimming and environmental-responsive control in larger setups.
• Irrigation and pump timing. Large-capacity submersible or inline pumps used in recirculating hydroponic systems, flood-and-drain tables, and drip systems often operate at 240 V. The Apollo 11 can automate pump cycles on a fixed schedule, replacing manual pump switching and reducing the risk of missed irrigation events.
• Ventilation fan control. High-capacity inline fans and exhaust systems used to manage temperature and humidity in larger grow rooms frequently run on 240 V circuits. Scheduling fan operation on the Apollo 11 allows growers to coordinate air movement with light cycles, CO2 injection intervals, or time-of-day temperature management strategies.
• Environmental control equipment. Air conditioners, dehumidifiers, and other climate control units in commercial grow rooms often require 240 V. The Apollo 11 can time when these units operate, particularly useful for pre-programming startup windows before lights-on periods or reducing operating hours during low-demand overnight periods.
• Single-device scheduling where simplicity is preferred. For operations that need to automate one piece of 240 V equipment on a consistent daily schedule, the Apollo 11 provides that capability without requiring a full multi-outlet controller. Its single-outlet design keeps the setup straightforward while still providing the flexibility of 20 daily schedules at 1-minute resolution. For cooling and airflow management, see also the Active Air HD pedestal fan as a compatible piece of environmental equipment.
• Backup timer in multi-zone rooms. In rooms where a primary environmental controller handles most equipment, the Apollo 11 can serve as a dedicated backup timer for critical single devices—ensuring that one piece of equipment maintains its schedule independently of the primary controller’s operation.

Titan Controls Apollo 11 vs Apollo 10 Mechanical Timer

The Titan Controls Apollo product line includes both digital and mechanical timer options at 240 V. The two closest variants at this voltage are the Apollo 11 (digital) and the Apollo 10 (mechanical). Growers choosing between them are primarily choosing between digital programming flexibility and the simplicity of a mechanical design. Understanding the distinction between these two approaches helps in selecting the right timer for a given application.

Control mechanism. The Apollo 10 is a mechanical timer. Like traditional analog plug-in timers, it uses a rotating dial with physical tabs or pegs that are pushed in or out to set on/off windows. The dial rotates continuously and trips the outlet switch as the pegs pass a contact point. The Apollo 11 replaces this mechanical approach with a digital interface. On/off times are entered as specific clock times through a digital keypad or button interface, and the timer executes those programs based on its internal clock rather than a rotating dial position.

Scheduling precision and flexibility. A mechanical timer’s precision is limited by the physical spacing of its time tabs—typically 15 or 30-minute intervals. The Apollo 11’s digital programming supports 1-minute intervals, which allows significantly tighter scheduling. The Apollo 11 also supports up to 20 independent on/off programs per day, whereas a mechanical timer is limited to the number of physical on/off transitions the dial format allows—typically far fewer and constrained to a single continuous block or a small number of repeating windows.

Battery backup. The Apollo 11 includes a battery backup feature that retains programmed schedules if main power is interrupted. A mechanical timer has no memory to protect: when power is restored after an outage, the dial resumes from its current physical position, which may or may not correspond to the correct time if the outage was long enough to shift the dial. Whether this matters depends on how long outages in a given facility tend to run and how precise the schedule needs to be.

Daylight savings adjustment. The Apollo 11 includes a daylight savings mode. On a mechanical timer, the clock time shifts automatically with the mechanical dial, but the actual on/off program timing relative to the real-world clock will drift by one hour at each daylight savings transition. Growers who need photoperiod timing to remain consistent relative to local clock time must manually adjust a mechanical timer twice a year. The Apollo 11’s daylight savings mode handles this adjustment without manual reprogramming.

Enclosure and durability. Both the Apollo 10 and Apollo 11 are Titan Controls products built for grow room use with heavy-duty construction. The Apollo 11’s enclosure is specified as resistant to dust, rust, and moisture. Both products are intended for grow room environments, though the specific enclosure ratings should be compared against the relevant product data sheets for each model when the application involves particularly harsh environmental conditions.

When to choose the Apollo 10. The Apollo 10 mechanical timer is appropriate when the scheduling requirement is a simple daily on/off window without need for multiple programs, when digital programming is considered unnecessary complexity for a given application, or when the operating environment does not require battery backup or daylight savings adjustment. Mechanical timers are generally more straightforward to operate and have no programming interface to learn.

When to choose the Apollo 11. The Apollo 11 is the better choice when precise scheduling at 1-minute resolution is needed, when multiple on/off windows per day are required, when battery backup is important to maintain schedule continuity through power interruptions, or when the grower wants to avoid manual clock adjustment at daylight savings transitions. For the same 240 V voltage rating, the Apollo 11 provides more scheduling flexibility at the cost of slightly greater programming complexity.

Compatibility & Operating Range

The Apollo 11 is designed for use with North American 240 V / 60 Hz electrical systems. Before connecting equipment to this timer, verify that both the outlet supplying power and the equipment being controlled meet the voltage and amperage specifications below.

Voltage and frequency requirement. The Apollo 11 requires a 240 V / 60 Hz power source. It cannot operate from a standard 120 V household outlet. In North America, 240 V circuits are typically dedicated circuits installed for appliances and high-draw equipment. The Apollo 11 must be plugged into a properly grounded 240 V / 60 Hz outlet. Operating at the wrong voltage can damage the timer and the connected equipment.

Maximum load rating. The Apollo 11 is rated for a maximum of 10 A at 240 V. Before connecting any equipment, calculate the total current draw of the device being controlled. If the connected equipment draws more than 10 A at 240 V, the Apollo 11 is not rated for that load and should not be used in that application. Growers who need to control higher-amperage loads at 240 V should look at dedicated relay systems or multi-zone controllers rated for the appropriate amperage.

Compatible equipment types. The Apollo 11 is designed to control any 240 V / 60 Hz device that draws 10 A or less. Typical grow room applications include HID lighting fixtures (HPS, MH), 240 V inline and centrifugal fans, 240 V submersible and inline pumps, and 240 V air conditioning or dehumidification units with appropriate amperage ratings. The single outlet limits the Apollo 11 to controlling one piece of equipment at a time; multi-device control requires a multi-outlet controller or relay panel.

Advanced lighting controller integration. Growers who need timer-based on/off control combined with intensity dimming or environmental-responsive light management can use the Apollo 11 alongside a dedicated controller such as the Autopilot PX2 advanced lighting controller. In that configuration, the Apollo 11 handles the on/off schedule for the high-voltage circuit while the Autopilot PX2 manages dimming and environmental response. These two devices operate at different functional layers and can be used in the same room for different control tasks.

Enclosure compatibility. The Apollo 11’s enclosure is rated to resist dust, rust, and moisture. This makes it suitable for placement in grow rooms, greenhouses, and other environments where airborne particulates and elevated humidity are present. It is not specified as waterproof or submersible; direct water exposure should be avoided. The timer should be mounted or placed in a position where it is not in the direct spray path of irrigation systems or misters.

Usage Guidelines

The Apollo 11’s digital interface allows growers to program specific on and off times for connected equipment. The following guidelines cover the key operational features: schedule programming, battery backup behavior, and daylight savings adjustment.

Setting the current time. Before programming any schedules, the Apollo 11’s internal clock must be set to the current time. Locate the time-setting controls on the digital interface—typically labeled with a clock icon or “TIME SET” function—and enter the current hour and minute. The timer uses this clock reference to execute all programmed on/off events. If the clock is set incorrectly, all scheduled events will occur at the wrong time relative to the real-world clock.

Programming on/off schedules. The Apollo 11 supports up to 20 independent on/off schedules per day. Each schedule consists of a specific on time and a specific off time, entered in hours and minutes using the digital interface. To add a schedule, enter the programming mode (typically by pressing a “PROG” or “SET” button), select an available schedule slot, and enter the desired on time followed by the desired off time. Repeat for each additional schedule needed. Schedules repeat daily by default once programmed.

Using 1-minute interval precision. Because the Apollo 11 supports 1-minute scheduling intervals, growers can create very precise lighting or irrigation windows. For example, a photoperiod schedule of exactly 18 hours on and 6 hours off can be set to start at a specific minute, not merely the nearest 15- or 30-minute mark. This level of precision is particularly useful when coordinating multiple pieces of equipment on different timers and maintaining exact schedule alignment between them.

Battery backup operation. The Apollo 11 includes battery backup to retain programmed schedules during power interruptions. When main power is lost, the battery maintains the internal clock and all stored schedule data. When main power is restored, the timer resumes executing schedules from the correct current time without requiring manual reprogramming. The battery backup does not power the timer’s outlet; connected equipment will remain off during a power outage regardless of what the schedule specifies. It only preserves the programming so the schedule can resume correctly once power is restored.

Replacing the backup battery. Over time, the backup battery will discharge and require replacement. Most digital timers of this type use a standard coin cell or AA battery for backup purposes. Consult the Apollo 11’s product documentation for the specific battery type required. A depleted backup battery does not affect normal timer operation while main power is present; it only affects whether schedules are retained during power interruptions.

Daylight savings mode. The Apollo 11 includes a daylight savings mode to accommodate clock time changes in spring and fall. When daylight savings mode is active, the timer will automatically adjust its internal clock by one hour at the appropriate transition, keeping scheduled events aligned to local clock time without manual reprogramming. Growers who prefer not to use this feature—for example, those running schedules based on an absolute elapsed-time basis rather than local clock time—can disable daylight savings mode through the timer’s settings. Refer to the product documentation for the specific steps to enable or disable this mode for your unit.

Load management. Do not exceed the 10 A maximum rating of the Apollo 11’s outlet. If the connected equipment is close to the 10 A limit, consider monitoring the actual current draw with a clamp meter to confirm it stays within the rated capacity under all operating conditions, including startup inrush current, which can briefly exceed steady-state draw for motors and HID ballasts.

How to Install / Setup the Titan Controls Apollo 11

Installation of the Apollo 11 is straightforward. The timer is a plug-in device; no hardwiring is required. The following steps outline the full setup process from initial placement through schedule verification.

1. Verify your electrical supply. Confirm that the outlet where the Apollo 11 will be plugged in is a properly grounded 240 V / 60 Hz circuit. The Apollo 11 cannot operate from a standard 120 V outlet. If you are unsure about your outlet’s voltage, use a multimeter or consult a licensed electrician before proceeding. Plugging a 240 V timer into a 120 V outlet, or a 240 V device into an improperly wired outlet, can cause equipment damage or create an electrical hazard.
2. Mount or place the timer near the 240 V outlet. Position the Apollo 11 in a location that allows the power plug to reach the 240 V outlet and the controlled equipment’s cord to reach the timer’s outlet. The enclosure is rated to resist dust, rust, and moisture, making it suitable for placement in a grow room. Avoid placing the timer in areas with direct water spray or pooling water. If wall-mounting is preferred, verify that the unit includes mounting provisions or use an appropriate bracket.
3. Plug the Apollo 11 into the 240 V / 60 Hz outlet. Insert the timer’s plug into the grounded 240 V outlet. The digital display should illuminate, indicating the unit is receiving power. If the display does not illuminate, check the outlet for power and verify the outlet is correctly wired.
4. Connect your equipment to the timer’s outlet. Plug the controlled device—grow light, pump, fan, or other 240 V equipment—into the Apollo 11’s single outlet. Confirm that the equipment’s current draw does not exceed 10 A at 240 V before making this connection. Do not connect a power strip or extension cord loaded with multiple devices to the timer’s outlet in a way that would exceed the 10 A limit.
5. Set the current time using the digital controls. Navigate to the time-setting mode on the Apollo 11’s digital interface. Enter the current time accurately. The timer uses this clock as the reference for all scheduled events. Double-check that AM/PM is set correctly if the display uses 12-hour format, or that the 24-hour time is entered accurately if the display uses 24-hour format.
6. Program up to 20 on/off schedules using 1-minute intervals. Enter the programming mode and create the desired on/off schedules. For each schedule, enter the specific on time and off time. You can create up to 20 separate programs. For example, a simple 18/6 light cycle might use a single program with an 18-hour on window. More complex irrigation routines with multiple short watering events throughout the day can use several programs within the 20-program limit. Review each programmed schedule after entry to confirm accuracy.
7. Verify battery backup is active. Consult the Apollo 11’s product documentation to confirm how to verify that the backup battery is installed and functional. Some digital timers indicate battery status on the display; others require testing by briefly disconnecting main power and confirming that the display remains active on battery alone. Ensure the battery backup is working before leaving the timer unattended for extended periods.
8. Test the programmed schedules. After programming, observe the timer through at least one on and one off event to confirm the connected equipment responds correctly at the programmed times. If the equipment does not turn on or off at the expected time, review the programmed schedule entries for any input errors and re-enter corrected schedules as needed.
