AC Infinity Controller 75 PRO Smart Climate Controller 2-Outlet – WiFi, Bluetooth, Temperature, Humidity & VPD Automation

The AC Infinity Controller 75 PRO is a smart 2-outlet climate controller that automates compatible outlet-powered equipment based on temperature, humidity, VPD, timers, cycles, and schedules. Designed for grow tents, hydroponic systems, indoor gardens, greenhouses, propagation areas, HVAC applications, and other controlled environments, it makes it easy to add intelligent environmental automation to equipment that uses a standard AC power plug.

Equipped with two independently programmable outlets, the Controller 75 PRO can operate two compatible devices separately from one centralized controller. Its included 12' temperature and humidity sensor probe continuously monitors environmental conditions and calculates VPD, while built-in WiFi and Bluetooth connectivity provide remote access through the AC Infinity app.

With support for a combined load of up to 1100 W and 10 A, the Controller 75 PRO is an excellent solution for automating compatible fans, humidifiers, heaters, seedling heat mats, and other outlet-powered environmental equipment.

Two Independently Programmable Outlets

The Controller 75 PRO features two AC power outlets that you can program independently, so each connected device can follow its own environmental or time-based operating rules.

For example:

Outlet 1 – Ventilation Fan
Can activate when temperature or humidity rises above a programmed threshold.

Outlet 2 – Humidifier or Heat Mat
Can activate according to its own humidity, temperature, VPD, cycle, or schedule settings.

Because each outlet operates independently, growers can coordinate multiple environmental functions without requiring separate controllers for every device.

Temperature-Based Automation

The included climate sensor continuously measures temperature and lets the Controller 75 PRO automatically turn compatible equipment ON or OFF based on programmed temperature thresholds.

This makes it suitable for controlling devices such as:

• Exhaust fans
• Intake fans
• Circulation fans
• Heaters
• Seedling heat mats
• Other temperature-responsive equipment

The controller supports programmable temperatures ranging from approximately 32 to 140°F.

Humidity-Based Automation

The Controller 75 PRO also monitors relative humidity, allowing connected devices to react automatically as humidity conditions change.

Compatible equipment can be programmed to turn on when humidity becomes too high or too low, depending on the intended application.

This makes the controller useful for automating:

• Humidifiers
• Exhaust fans
• Ventilation systems
• Other compatible humidity-control equipment

By reacting to real-time sensor readings, the controller reduces the need for frequent manual adjustments.

VPD Monitoring & Triggers

The Controller 75 PRO supports VPD (Vapor Pressure Deficit) monitoring and programming.

Using temperature and humidity readings from the included sensor, the controller calculates VPD and allows connected equipment to operate according to programmed VPD thresholds.

This provides growers with an additional environmental-control option beyond temperature and relative humidity alone.

Custom Buffer Settings

The Controller 75 PRO includes custom buffer settings that help fine-tune when connected equipment switches on or off around environmental trigger points.

Buffers can help prevent equipment from rapidly cycling when temperature, humidity, or VPD readings fluctuate around a programmed threshold.

This allows smoother, more controlled equipment operation.

Timer Programming

The controller includes timer functions for applications that require equipment to run for a specific period.

Timer programming can be useful for:

• Ventilation
• Heating
• Humidification
• Propagation equipment
• Other timed environmental applications

This adds flexibility beyond sensor-based automation.

Cycle Mode

Cycle Mode allows connected equipment to alternate between programmed ON and OFF intervals continuously.

For example, a fan or other device can run for a specified period, switch off for another period, and then repeat the cycle automatically.

This function is particularly useful for equipment that needs intermittent operation rather than continuous use.

Schedule Mode

The Controller 75 PRO also includes daily scheduling, allowing compatible equipment to run at specific times.

Schedules can be used to coordinate equipment with:

• Lighting periods
• Day/night cycles
• Propagation routines
• Ventilation schedules
• Heating or humidity requirements

This lets you automate equipment based on both environmental conditions and time of day.

WiFi & Bluetooth Connectivity

The Controller 75 PRO supports both WiFi and Bluetooth connectivity, allowing it to connect with the AC Infinity app.

Bluetooth provides local wireless access, while WiFi enables remote monitoring and adjustment through the app when an internet connection is available.

This gives you convenient access to environmental information and controller settings without requiring you to stay beside the growing environment.

AC Infinity App Control

Connecting the Controller 75 PRO to the AC Infinity app unlocks additional smart-control features.

Through the app, users can:

• Monitor temperature
• Monitor humidity
• Monitor VPD
• Adjust outlet programming
• Create advanced automation
• Set timers
• Create cycles
• Program schedules
• Configure alerts and notifications
• Review historical climate data
• View environmental charts and graphs
• Export data in CSV format

This makes it easier to monitor environmental conditions and manage compatible equipment from one interface.

Custom Alerts & Notifications

The AC Infinity app allows users to configure custom environmental alerts and notifications.

These can help identify conditions that move outside the desired temperature, humidity, or VPD ranges.

Remote notifications provide additional environmental awareness when users are away from the grow tent or cultivation area.

Historical Climate Data

The Controller 75 PRO can record environmental information for viewing through the AC Infinity app.

Historical climate charts can help users review changes in:

• Temperature
• Relative humidity
• VPD
• Environmental patterns
• Equipment activation trends

You can also export data in CSV format for record-keeping or additional analysis.

12' Temperature & Humidity Sensor Probe

The included sensor probe features a generous 144" (12') cable, letting you place the sensor inside the growing environment while keeping the controller conveniently accessible outside or nearby.

The sensor uses a water-resistant thermal-alloy head designed to accurately monitor current temperature and humidity conditions.

Because VPD calculations depend on climate readings, proper probe placement helps provide more representative environmental measurements.

Supports Up to 1100 W

The Controller 75 PRO's two outlets collectively support compatible equipment up to 1100 W, with a maximum rated current of 10 A.

This lets the controller run a variety of outlet-powered environmental devices.

Always verify the electrical requirements of connected equipment and ensure the combined load of both outlets remains within the controller's 1100 W / 10 A rating.

Compatible with Standard Outlet-Powered Equipment

Unlike UIS controllers that connect directly to compatible UIS devices, the Controller 75 PRO is designed primarily for equipment using standard AC power plugs.

Compatible applications can include:

• Inline duct fans
• Shutter exhaust fans
• Clip-on circulation fans
• Seedling heat mats
• Humidifiers
• Heaters
• Ventilation equipment
• Other compatible outlet-powered environmental devices

This makes the Controller 75 PRO especially useful for adding smart automation to equipment without built-in UIS controls.

Backup Memory

Integrated backup memory retains the controller's programmed settings if power is interrupted.

When power returns, the system can resume operation without requiring users to manually re-enter their previous programming.

This is particularly useful for automated grow environments where maintaining programmed settings is important.

Large Backlit Digital Display

The Controller 75 PRO features a large backlit LCD display that clearly presents environmental readings and controller settings.

Users can view temperature in either Fahrenheit or Celsius, along with humidity, VPD, outlet status, and programmed functions.

The desktop-style controller provides convenient access to environmental information without requiring a mobile device.
