3.2. Application Controllers - VAV Controllers


VAV Controller
enteliZONE VAV Controller: eZV-440
The enteliZONE eZV-440 is a native BACnet® controller with a integrated airflow sensor and damper actuator for VAV applications available in both configurable and programmable versions. The configurable model (eZV-440) comes pre-loaded with a flexible factory algorithm covering typical VAV applications enabling quick setup and commissioning. The programmable model (eZVP-440) has the letter "P" in the model name. The programmable model enables full control sequence customization and/or repurposing of unused I/O points. The eZV communicates using BACnet MS/TP on its RS-485 main LAN port. It also has a RS-485 subLAN port for the optional addition of LINKnet eZNS or DNS smart network sensor(s). With 4 universal inputs, 4 universal outputs for external field devices plus a onboard airflow sensor and actuator (optional) the eZV-440 has the I/O to cover a wide range of VAV configurations, including multi-stage reheat with analog, binary or floating actuators, and series or parallel fan boxes. 

DVC-304 Controller:
The DVC-V304 is a programmable Variable Air Volume (VAV) controller with 3 external inputs, and 4 TRIAC outputs. The input for the flow sensor and outputs for the tri-state actuator are not included. The controller supports flash loading Modbus upgrades via a purchased hardware key. The DVC-V304 is a fully programmable, Native BACnet®, Advanced Application Controller that communicates on an RS-485 LAN using the MS/TP BACnet protocol.
The DVC-V304E is a fully programmable, Native BACnet®, Advanced Application Controller that communicates on a Twisted Pair 10-BaseT BACnet/IP and BACnet over Ethernet network.
The DVC-V304PoE is a fully programmable, native BACnet®, Advanced Application Controller for VAV applications featuring Power over Ethernet (PoE).

 

DVC-V322 Controller: 
This is a programmable Variable Air Volume (VAV) controller with 3 external inputs, 2 analog outputs, and 2 TRIAC outputs. The input for the flow sensor and outputs for the tri-state actuator are not included. The controller also supports flash loading Modbus upgrades via a purchased hardware key.
The  DVC-V322 is a fully programmable, Native BACnet®, Advanced Application Controller that communicates on an RS-485 LAN using the MS/TP BACnet protocol.
The DVC-V322E is a fully programmable, Native BACnet®, Advanced Application Controller that communicates on a Twisted-Pair Ethernet 10-BaseT using BACnet/IP and BACnet over Ethernet.
The DVC-V322PoE is a fully programmable, native BACnet®, Advanced Application Controller for VAV applications featuring Power over Ethernet (PoE)

DNT-VAV-DG1 VAV Controller: 
This product is a combination of a Delta Network Thermostat (DNT-T103) and a Variable Air Volume (VAV) Termination board (DTM-VAV-DG1). This makes field installation easier because the actuator and flow sensor are mounted as part of the termination board.

 

DZNT VAV/VVT Zone Controller:
The Delta Zone Controller with Network Thermostat (DZNT) Variable Air Volume (VAV) Application Specific Controller product line is suitable for controlling nearly all basic VAV, fan powered VAV or Variable Volume and Temperature (VVT) sequences with choices of 3-stage digital reheat, tri-state with 2nd stage digital reheat or analog with 2nd stage digital reheat. Features include auto heat/cool changeover, digital time clock or motion sensor input, timed overrides for occupancy handling and configurable reverse acting digital reheat stages. The DZNT VAV products come with built-in field configurable VAV or VVT algorithms; they are not programmable with GCL+.
