Introduction de produit

This local controller adjusts a compatible brushless EC fan from 1% to 100% through an onboard potentiometer. LED indicators provide basic diagnostics without requiring a building network, PLC or supervisory software. It is the simplest option for individual FFUs and small cleanrooms where each operating point is set at the unit.

Key Features

Direct local adjustment

Technicians set fan duty at the controller without digital addressing.

Full stated range

The potentiometer covers 1% through 100% command.

Basic visual feedback

LEDs indicate controller or fan status during setup.
