New controller for the intelligent fan range – i3Fan

Fläkt Woods has redesigned the controller unit for its revolutionary intelligent control system, offering customers automated ventilation on demand, with an easy to use control interface. It also features improved connection and expansion options.

The i3Fan intelligent controller optimises fan energy usage by adjusting power consumption to match system demands. The new user interface has embedded software that is easier to use and understand. In addition, the hardware has been redesigned, enabling the users to combine it with other remote speed controllers and frequency invertors within Fläkt Woods e3 range.

A simplified control interface uses four buttons, which allow users to quickly navigate through options within the menu system. Parameters are easy to find and set as they are stated in plain in English. Installation is fast and simple; as controllers feature externally mounted gland connectors (fan unit and power wiring connections) and blanking plugs (for plug and play sensors), thus making it easy to connect the appropriate sensors and power supply. The controller is programmed to be enabled within an existing BMS system, or it can act independently.

This logic has already proved itself on the original iFan controller, significantly reducing enabling times and leading to optimised installation costs. Plug and play sensor connectors can also provide quick simple installation for remote sensors (up to 8 per fan). These include; CO2 detection, humidity level control, temperature and pressure sensing. Contractors have only to determine the maximum demand and what conditions need to be monitored.

The new unit can be operated using a remote keypad, a useful option if the controller is located within a ceiling void. Fans can be interconnected so that they are controlled by the same switching devices and condition sensors. This is an extremely useful feature when a number of systems serve the same area.

Built-in flexibility means the new unit has been designed to be intuitive, allowing future applications to be added as and when they are required. Control Logic software allows for future enhancements and software updates to be applied.

Controllers can be retrofitted to existing fans, offering building owners a significant opportunity to save power and therefore money. Fläkt Woods has proved that the units can often pay for themselves in under a year.
