Aquafog Two-Stage Control

The Aquafog Two-Stage Control is a professional environmental controller designed for high-humidity applications where ventilation, temperature changes, and changing environmental conditions require flexible fogging output.

Designed specifically for compatible Aquafog Turbo XE systems, the 2SC-120 combines a 24-hour timer and thermostat into a two-stage control system. Stage one provides base fogging according to the timer schedule, while stage two automatically increases fogging output as temperatures rise.

This two-stage approach is particularly useful in greenhouses and propagation environments where ventilation can rapidly remove humidity, and additional fogging capacity may be required to maintain stable conditions.

Automatic Two-Stage Environmental Control

The Aquafog Two-Stage Control automatically adjusts fogging operation as environmental conditions change.

The system uses two separate stages:

Stage 1 – Timer-Controlled Base Fogging

The first stage establishes the normal fogging cycle using the integrated 24-hour timer.

This lets operators schedule regular Turbo XE operation based on the facility's environmental requirements.

Stage 2 – Temperature-Controlled Boost

When temperatures increase, the thermostat activates the second stage to provide additional fogging output.

This is particularly valuable when greenhouse ventilation increases during warmer conditions because ventilation can quickly remove moisture from the growing environment.

By increasing fogging output as temperatures rise, the Two-Stage Control helps compensate for changing ventilation and humidity conditions.

Designed for High-Humidity Applications

The 2SC-120 is especially well suited for environments where maintaining elevated humidity matters but conditions are constantly changing.

Typical applications include:

• Greenhouse propagation
• Plant propagation facilities
• Controlled-environment agriculture
• High-humidity horticulture
• Mushroom production
• Agricultural facilities
• Industrial humidification
• Facilities with temperature-driven ventilation
• Applications requiring changing fog output throughout the day

Rather than operating the fogging system at one fixed output level, the two-stage system allows the installation to respond more effectively as conditions change.

24-Hour Rain-Tight Timer

The Two-Stage Control incorporates a 24-hour rain-tight timer with adjustable operating cycles.

For the 2SC-120 / 60 Hz model, the timer uses a mechanical design that provides straightforward scheduling without complicated digital programming.

The timer controls the normal first-stage fogging operation and provides the foundation for the two-stage sequence.

This allows operators to establish a consistent base fogging schedule while allowing the thermostat to automatically increase output when higher temperatures demand additional moisture.

Temperature-Responsive Second Stage

The second stage responds to temperature changes.

As temperature rises and ventilation increases, additional fogging may be needed to replace humidity lost through air exchange.

The thermostat-controlled second stage automatically increases fogging output under these warmer conditions.

This can help:

• Compensate for increased greenhouse ventilation
• Maintain more consistent humidity
• Reduce sudden humidity drops
• Increase fogging output during warmer periods
• Reduce the need for manual adjustment
• Improve environmental consistency
• Adapt fogging performance to changing conditions

Controls Up to Two Turbo XE Units

The Aquafog Two-Stage Control can control up to two compatible Turbo XE units.

This makes the 2SC-120 useful for larger greenhouse, propagation, agricultural, and industrial installations where a single controller needs to manage more than one fogging unit.

The two connected Turbo XE systems can operate together as part of the two-stage environmental-control strategy.

Used With / Compatible With

The Aquafog Two-Stage Control 2SC-120 is designed for compatible 115 V / 60 Hz Aquafog Turbo XE systems.

Compatible applications can include:

• Aquafog Turbo XE 2000 Fans – compatible 115 V configuration
• Aquafog XE-2000 – 115 V / 60 Hz direct-feed configuration
• Up to two compatible Turbo XE units
• Compatible Turbo XE direct-feed fogging installations
• Appropriate Turbo XE water-control equipment
• Compatible Aquafog mounting accessories such as the XE-100 Traveling Floor Stand, XE-110 Molded Floor Stand, XE-W Wall Mount, and XE-C Ceiling Mount
• Compatible environmental monitoring instruments such as the CP-205 Temperature-Humidity Meter and CP-301 Temperature-Humidity Meter with Dew Point

The current manufacturer identifies the 2SC-120 as the 115 V/60 Hz Two-Stage Control for Turbo XE systems.

Important Electrical Compatibility

The 2SC-120 is designed for:

• 115 V
• 60 Hz
• Compatible Turbo XE systems

Do not connect the 2SC-120 directly to incompatible higher-voltage or three-phase equipment.

Other voltage-specific Two-Stage Control configurations have historically been available for higher-voltage or international applications, so installations using non-115 V Turbo XE equipment should use the control configuration that matches the electrical system.

Always verify the voltage, phase, and connected load before installation.

Ideal for Changing Greenhouse Conditions

Greenhouse environments can change rapidly throughout the day.

During cooler periods, lower ventilation rates may allow humidity to remain relatively stable with only the base fogging output.

As temperatures rise, greenhouse vents or exhaust systems may operate more aggressively, causing humidity to leave the growing space more quickly.

The Two-Stage Control is designed around this changing pattern:

• Stage 1 maintains normal scheduled fogging
• Stage 2 adds fogging output when temperature increases

This makes the system especially useful for propagation environments where maintaining adequate humidity during ventilation periods is important.

Simple Combination of Timer and Thermostat Control

Instead of requiring separate manual adjustments throughout the day, the Two-Stage Control combines two proven control methods into one coordinated system:

• Timer-based operation
• Temperature-based operation

The timer establishes the normal operating schedule, while the thermostat responds automatically when environmental conditions require additional fogging.

This combination helps provide more responsive environmental management without requiring constant operator intervention.

Responsive Two-Stage Fogging Control

The Aquafog Two-Stage Control provides a practical way to manage Turbo XE fogging output when temperature and ventilation conditions change throughout the day.

By combining timer-controlled base fogging with thermostat-controlled boost output, the 2SC-120 allows compatible Turbo XE systems to respond automatically when warmer conditions create greater humidity demand.

For greenhouses, propagation facilities, agricultural operations, and professional high-humidity environments, the Aquafog Two-Stage Control provides a flexible solution for maintaining more stable environmental conditions while reducing the need for constant manual adjustments.
