Ventilation VRF DX Kit for air handling unit
Multiple temperature sensors optimally control an air handling unit and a fan coil unit.
When connected to an air handling unit (AHU), the temperature of supply air is controlled by a discharge sensor.
When connected to a fan coil unit (FCU), the room temperature is controlled by a return-air temperature sensor.
