Developed by Global Air Supplies specifically for indoor climate rooms, the EC5 goes beyond basic thermostat control. Reactive Temperature Technology (RTT) gives the controller a built-in microchip that actively monitors your environment and responds proportionally to temperature changes, whether that is a gradual rise requiring a measured speed increase or a sudden spike demanding an immediate response. The result is a grow room that stays within your target range without the temperature swings that basic on and off controllers produce.\u003c\/p\u003e\u003cp\u003eThe EC5 plugs directly into any Systemair EC fan with no power pack required, drawing power from the fan itself for a clean, cable-efficient setup. Fan balancing for both intake and exhaust is built in, allowing you to dial in negative pressure and prevent odour escape without a separate balancer unit. For growers running EC fans who want intelligent, integrated climate control, the EC5 is the purpose-built solution.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReactive Temperature Technology (RTT).\u003c\/strong\u003e Built-in microchip monitors your climate room continuously.

The built-in RTT microchip reads ambient temperature continuously and adjusts fan speed in proportion to how far conditions have drifted from your set point. A small rise gets a measured response. A sudden spike gets an immediate one. The fan balancing system lets you set independent speed ranges for intake and exhaust, with negative pressure control built in so your room stays sealed against odour escape. Everything is managed from one controller, with no additional hardware required.\u003c\/p\u003e\u003ch3\u003eSystem Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type.\u003c\/strong\u003e EC fan speed control with Reactive Temperature Technology.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRTT Microchip.\u003c\/strong\u003e Proportional temperature response, gradual and rapid spike management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan Balancing.\u003c\/strong\u003e Integrated intake and exhaust balancing with negative pressure control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed Settings.\u003c\/strong\u003e Adjustable maximum and minimum fan speeds for intake and extraction independently.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source.\u003c\/strong\u003e Powered directly from EC fan.

It is built specifically for EC fan systems, with RTT microchip technology that understands the difference between a gradual temperature drift and a sudden spike and responds to each appropriately. The integrated fan balancer and negative pressure control remove the need for separate hardware, keeping your setup clean and your points of failure low. And because it draws power directly from the fan, there is no power pack to manage or fail. For growers running Systemair EC fans who want the most capable, purpose-built controller for their system, the EC5 is the direct answer.\u003c\/p\u003e\u003ch3\u003eEnviro, Enviro V2, or EC5: Which GAS Controller Is Right for You?\u003c\/h3\u003e\u003cp\u003eGAS makes three controllers suited to different levels of grow room automation.

EC controllers require EC-motor fans for full variable-speed control — they are not compatible with standard AC-motor fans. AC fan controllers work with standard single-phase AC fans. Check the compatibility list for your specific fan model before purchasing GAS EC5 Fan Controller if you are retrofitting to an existing setup.\u003c\/p\u003e\n\u003ch3\u003eHow does GAS EC5 Fan Controller automate my grow room climate?\u003c\/h3\u003e\n\u003cp\u003eGAS EC5 Fan Controller monitors temperature and\/or humidity via its onboard or external probe and automatically adjusts fan speed to maintain your target setpoints. When temperature rises above your target, fan speed increases to extract warm air. When temperature drops, fan speed reduces to conserve heat. This removes the need for manual fan adjustments and keeps your grow room dialled in 24\/7.\u003c\/p\u003e\n\u003ch3\u003eCan I use GAS EC5 Fan Controller with both my intake and exhaust fans?\u003c\/h3\u003e\n\u003cp\u003eMost fan controllers including GAS EC5 Fan Controller are designed to control your primary exhaust fan. Some models include dual-channel control for both intake and exhaust. Check the number of output channels and maximum load rating before connecting multiple fans — never exceed the controller's maximum amperage rating.\u003c\/p\u003e\n\u003ch3\u003eDoes GAS EC5 Fan Controller ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — GAS EC5 Fan Controller ships from our Australian warehouse with fast tracked delivery Australia-wide.
