Stand-alone Terminal Unit

with PICV control


The room temperature in different applications, such as Fan Coil Units, Chilled Beams, Chilled Ceilings, Trench Heaters, is controlled by a room controller.

The room controller has a built in temperature sensor and delivers an output signal to the PICV actuator.

The control signal can either be modulating or on/off depending on the system layout.
