Control a fan


Fan speed controllers regulate the supply of fresh air or the exhaust of stale air in function of the need. The air flow volume can be adjusted manually or automatically according to the demand. In case of manual control, the fan speed can be adjusted via a switch or potentiometer. This can be done locally or remotely. For automatic fan speed control, an HVAC sensor is connected to the AC fan speed controller or EC fan.

Local fan speed control

Local fan speed control
Fan speed can be set manually via a knob or potentiometer on the front panel of the fan speed controller. These fan speed controllers have a built-in switch or potentiometer to adjust the fan speed.

Remote fan speed control

Remote fan speed control
Fan speed can be set manually via a separate potentiometer or control switch. The external potentiometer or switch can be installed nearby the fan speed controller or in a separate room. Via this separate potentiometer or switch, the requested fan speed is sent to the AC fan speed controller or to the EC fan.

Demand based fan speed control

Demand based fan speed control
Fan speed is automatically optimised based on the measurements of the HVAC sensor. These solutions optimise indoor air quality and the comfort of the occupants in a discrete way. Significant energy savings can be realised. Fan speed is automatically controlled in function of temperature, humidity, CO2, TVOC, CO or differential pressure.
