Brief description
Applications The ZEV adjustment tool enables the operating volumetric flow settings in VAV and CAV sys-
tems with conventional control to be adjusted on site. It is not suitable for systems with an MP
bus connection.
Can be used with
– NMV-D2, VRD2, VRD2-L 1)
– LMV-D2M, NMV-D2M 2)
– LMV-D2-MP, NMV-D2-MP, SMV-D2-MP 2) 3)
– LHV-D2M 2) 3)
Connection The ZEV is connected to the VAV-Compact using the PP (peer-to-peer) interface of the VAV
controller.
As well as using the service socket on the VAV-Compact, it is also possible to connect the ZEV
to easily accessible connection points such as the service plug on the CR24-B room tempera-
ture controller or on the terminals in the control cabinet. This means there is no need for direct
access to the VAV controller.
Supply The 24 V supply to the ZEV comes via the service socket of the VAV, CR24 controller or from a
local 24 V supply, e.g. connection terminals of the VAV controller.
VAV-Compact The VAV-Compact devices do not have any operating elements such as switches or setpoint
potentiometers. If necessary, the operating parameters are set using the ZEV or another adjust-
ment tool, e.g. the PC-Tool with additional functions such as trend, etc.
VAV-Universal In the VRD2(-L), it is possible to set the mode appropriately for the selected 0…10 V or 2...10 V
room temperature controller.

The ZEV is connected to connections 1 and 5 of the correspond-
ing controller. The ZEV supply (AC/DC 24 V) comes directly from
connection 2.
When the system is being wired up, it is advantageous for the
actual value signal U5 (terminal 5) of the VAV controller to be fed
back to the room temperature controller or into the control cabinet.
Communication is via a peer-to-peer connection (PP).

Note
• When an operating device (e.g. ZEV) is con-
nected via the U/-PP connection (terminal 5) of
the VAV controller, the voltage signal of output
U5 does not correspond to the current actual
value signal.
When using the service socket of an LMV-D2-
MP, NMV-D2-MP or SMV-D2-MP, the U5 signal
is not impaired.
• The maximum communication level is DC 15 V.
To prevent damage to third-party equipment, it
may have to be disconnected from terminal 5
under certain circumstances – for the duration of
communication.
Safety notes
!
• The device is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• Only for Belimo VAV devices with 24 V safety extra-low voltage.

1) See product information for VAV-Compact and VAV-Universal
2) Lowest setting depends on the creep flow suppression. See VAV product information documents or refer to data from the VAV manufacturer.
3) ZEV devices (manufactured before 8/2006) need a modified scale sticker. Please contact your Belimo branch.
4) The "Constant" option is irrelevant for the current VRD2, L/NMV-D2M and L/N/SMV-D2-MP versions.
5) If the LED constantly displays low-power "dark" flashes (> 3 min), this means the actuator is most probably at a limit position.
