In case of connecting the air handling
unit, the supply air temperature is
controlled optimally by the discharge
temperature control.
In case of connecting the fan coil unit,
the room temperature is controlled
optimally by the intake temperature
control.

A variety of controls to match the
application
• Central control using our VRF controllers or central management
controllers
Supports a wide range of
capacity classes
• 2 EEV units can be connected in parallel and up to 20 HP (50
kW) large capacity units can be connected.
• Connectable capacity range: 5 kW to 50 kW
This kit can connect the general-purpose air
handling unit (AHU) and the fan coil unit (FCU)
to the VRF system.
It enables VRF system to control the operation
of both air conditioner and ventilation.
