Ventilation DX Kit for Air Handling Applications
Features
Different control strategies for optimized control of air handling & fan coil units
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.
Application as part of a VRF system
Supports a wide range of capacity classes
- Connectable capacity range: 18,000 BTU/h to 168,000 BTU/h
- 2 EEV units can be connected in parallel for up to 168,000 BTU/h large capacity units. (Separation Tube kit UTP-LX180A is required for 144,000 BTU/h / 168,000BTU/h.)
A variety of control options that meet application requirements
Central control using VRF controllers or central management (BMS) controller
Central control from external controllers
