AC Infinity Controller 67 Smart Bluetooth Fan Controller - Dynamic

In this review the AC Infinity Controller 67 is evaluated as a compact controller for growers and HVAC hobbyists who want smarter airflow control. The bottom line: it is best for users who run one or two EC motor fans and want automated, climate-driven speed control without wiring complex relay systems. The Controller 67 stands out because its dynamic programming adjusts fan speed to temperature and humidity conditions, which translates to steadier airflow and easier environment management for small grow tents or ventilated spaces.

Key Features

• Bluetooth app control: Pairing with the mobile app unlocks advanced programs, notifications, and a clear view of recent temperature and humidity readings for remote adjustments.
• Auto trigger speed control: The controller automatically changes fan speed based on temperature and humidity thresholds to maintain more consistent airflow and environment stability.
• Flexible scheduling: Built-in timers, schedules and grow cycles let users automate daily routines and custom on/off transitions without additional hardware.
• Dynamic speed programming: Custom transitions and minimum speed settings prevent abrupt changes and help preserve steady VPD and climate conditions.
• Dual fan support: Supports up to two CLOUDLINE, AIRLIFT, or CLOUDWAY EC motor fans so both intake and exhaust can share the same programming and triggers.

Who It's For

The Controller 67 is ideal for hobby growers, small commercial setups and DIY HVAC users who already own EC motor fans and want a compact, programmable controller to manage temperature and humidity automatically. Its app features and advanced programming make it a good fit for operators who value remote adjustments and data visibility.

It is less appropriate for users who need wired network integration beyond Bluetooth or those who expect a very simple plug-and-play interface without learning the app's options; some users find the interface less intuitive and may prefer a basic manual controller instead.

Pros & Cons

Pros

• High controllability with app-based programming and notifications for remote monitoring.
• Good value for money given the dynamic triggers, schedules and dual-fan support.
• Quality build and reliable hardware that pairs well with EC motor fans used in ventilation systems.

Cons

• Some users report the interface and settings can feel cryptic at first, requiring time to learn the app and programming flow.

Our Verdict

The AC Infinity Controller 67 is a practical, cost-effective choice for anyone running EC motor fans who wants automated, climate-aware control. It delivers precise fan adjustments, useful scheduling and good app-based oversight, making it strong value for growers and small HVAC projects; buyers who need ultra-simple controls or full network integration should consider alternatives.

Frequently Asked Questions

Can it control more than one fan?
Yes. It supports up to two compatible EC motor fans sharing the same programming and triggers.

Does it monitor humidity as well as temperature?
Yes. The controller uses both temperature and humidity to dynamically adjust fan speed for better climate control.

Is the app required to use the controller?
The unit can run onboard programs, but the Bluetooth app is needed to unlock advanced programs, view climate data and receive notifications.
