Product Description
The Delta VAV Termination (DZNT) solution consists of an
intelligent LCD thermostat (DZNT-T0-VAV) and remote
termination board (DZTM) for mounting on the VAV/VVT unit.
The thermostat has an LCD display, four pushbuttons for setpoint
and occupancy override, and contains a variety of configurable
VAV/VVT algorithms suitable for controlling all three remote
termination board types.
Every remote termination board comes complete with a damper
actuator, flow sensor for VAV models, and housing. They are also
capable of fan control, reheat control and automatic heat/cool
changeover.
Important Information
1.
The Termination Board mounted to the VAV/VVT box is not a programmable
controller. All control and network functions are performed by the DZNT-T0-
VAV.
2.
DZNT-T0-VAVs may be part of an MS/TP network or stand-alone. However, a
stand-alone DZNT-T0-VAV does not have a time clock or scheduling functions.
Occupied and Unoccupied periods are determined by airflow or a BAS contact
closure on IP3.
3.
DZNT-T0-VAV used for VAV / VVT termination may not be used on LINKnet
networks.
4.
Data exchange may be done in GCL programming in any DCU or Application
Controller on the MS/TP network.
5.
Because of the fixed objects in the controller, alarming and trending must be
carried out by different controller on the network. Be aware that large numbers of
DER objects will affect the Scan Rate of those controllers. If the requirements call
for trending or alarming, it is recommended that you limit the number of DZNT
VAV devices so a maximum of 200 DER objects are created on any one system
panel.
