Variable Air Volume Controller with Actuator
for BACnet® MS/TP Communication
General
Infilex VC Model WY5706C is our new VAV controller with an
actuator that communicates via BACnet MS/TP. Infilex VC
provides high-performance DDC of VAV unit in a building
air-conditioning system. Thus, Infilex VC, networked even
within a complicated HVAC system, controls VAV unit.
Besides, Infilex VC offers building owners and operators the
flexible and enhanced controls of temperature and VAV for
various VAV units.
Infilex VC sends unique energy-saving information to its
networked BACnet zone controller, enhancing overall
controllability of a building management system.
DDC: Direct digital control
HVAC: Heating, ventilation, and air conditioning
VAV: Variable air volume
Features
BACnet® VAV controller:
Infilex VC Model WY5706C is integrated in the BACnet
MS/TP network.
Economical efficiency:
- Temperature and air-volume are controlled by a single
controller.
- VAV controller that resides on an actuator offers great
value.
Wide range of application:
Most of the major VAV types for industry are
preconfigured in the controller.
Unique energy conservation control:
- VAV damper opens wide to minimize the fan power
consumed by static pressure.
- Network with a zone controller allows supply air
temperature to be modified at an optimum level.
Infilex™ VC
Advanced building management integrated into BMS:
Our digital user terminal Neopanel enables users and
operators to modify the preset setting of temperature and
operating schedule (to extend) and offers flexibility of
temperature control and schedule control.
BTL certified product:
Infilex VC Model WY5706C is a BACnet® Application
Specific Controller (B-ASC).
CE Marking certified product:
Infilex VC Model WY5706C conforms to all the
applicable standards of CE Marking.
