FRC-2 Simple Fan Speed Dimmer

The TrolMaster FRC-2 Simple Fan Speed Dimmer is a manual controller for the Aero-Fan ventilation line of electronically commutated (EC) fans. It consolidates speed control for one or more Aero-Fan units, using a single front‑panel knob to set output from 0–100%. The module communicates digitally with the EC motor to provide smooth, hum‑free adjustment and matched speeds across grouped fans. The FRC-2 operates on 12 V DC at 0.1 A and ships with an ECS‑9 cable for plug‑and‑play connection to compatible Aero‑Fan models. Basic environmental integration is not required; the FRC‑2 functions as a standalone dimmer for ventilation airflow. Physical specs: 6.70 × 3.54 × 2.12 inches, 0.265 lb, operating range 32–104°F and ≤90% RH.
