Infilex™ VC
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.
●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.

(For example, the sign on the left indicates general instructions.)
WARNING
Before wiring and maintenance, be sure to turn off the power to the product.
Failure to do so might cause electric shock.
To control a VAV unit with electric heater, be sure to provide a circuit to prevent temperature rise.
Failure to do so might cause fire or overheating.
To control a VAV unit with electric heater, configure the system so that air conditioning unit will not stop when the VAV
unit is turned off. This allows the electric heater to cool down after it is turned off.
Failure to do so might cause fire or device damage.
CAUTION (1/2)
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
Install and use the product in a location that meets the operating conditions (temperature, humidity, power, vibration,
shock, mounting direction, atmospheric condition, etc.) as listed in the specifications.
Failure to do so might cause fire or device failure.
All wiring must comply with applicable codes and ordinances.
Make sure all the wires are tightly connected to the corresponding terminals.
Failure to do so might cause device failure or overheating.

For wiring, strip each wire insulation as specified in this manual. If the strip length is longer than the specified, the
stripped part of the wires will be exposed, causing electric shock or short circuit between adjacent terminals. If it is
shorter, the stripped part will not contact the connector.
If more than the rated power voltage is applied to the product, replace the product with new one for your safety.
Failure to do so might cause device failure or overheating.
Be sure to provide a circuit breaker for the power to the product as the product does not have a power switch.
Do not test the withstand voltage of the product.
Doing so might cause accident or device failure.

Wiring
Push-in terminal connection
Wires of power supply and DO (digital output) are connected to the push-in terminal block. Follow the procedure below for the
wiring connections.
1) Strip the 5-6 mm insulation of the wire end. (If the insulation stripped part is longer than the specified, it will be exposed
causing electric shock or short-circuit between adjacent terminals. If it is shorter, the wire may not contact the terminal.)
2) Make sure that any wire fiber is unbound from the wire end.
3) Insert a slotted screwdriver into a smaller square hole (for clamp release) on the terminal block located on the front surface.
To insert the screwdriver to the deep end (approx. 10 mm deep), push and tilt it (towards the front surface of Infilex VC main
unit) along the curving surface inside the square hole.
When the screwdriver is inserted to the deep end, the clamp is completely released.
Notes:
* A slotted screwdriver with the blade 3.5 mm wide and 0.5 mm thick (straight type) is acceptable. A screwdriver with the blade tip
narrower than the shaft may not be acceptable.
* Appropriate screwdriver (an example):
Model 9900 (3 mm wide x 100 mm long) or Model 910 (3 mm wide x 75 mm long) manufactured by Vessel Co., Inc.
* Since the terminal block has the inclined surface, required clearance for maintenance varies depending on the length of the screwdriver
to be used.
4) Insert the wire end into a larger square hole. When the wire end is fully inserted, remove the screwdriver.
5) Gently pull out the wire to make sure it is completely held by the clamp.
Wiring of user terminal / Pt100 temperature sensor to Infilex VC
User terminal and Pt100 temperature sensor are wired to Infilex VC with modular connection. For correctly crimping modular
plugs on a LAN cable, refer to the following.
Modular connector connection
Modular connector is composed of a modular plug (male) and a modular jack (female). Modular jacks are provided on Infilex VC,
and modular plugs will be crimped on LAN cables as required. Refer to the following procedure for crimping the modular plugs
on the LAN cables and connecting them to the modular jacks.
Note:
* For modular plugs, refer to Note *1 of the Input/output specifications section.

AB-7177
19
Procedure for modular connector connection
1) Strip the outer sheath of a LAN cable end. Be sure not to scratch or peel off any wire insulation when stripping the sheath.
Figure 17. Stripping the sheath
Make sure there are eight wires inside the sheath.
2) Align the eight wires in the order specified by the LAN cable manufacturer.
An alignment example of the LAN cable wires is shown in the table below.
Figure 18. Alignment of the wires
Note:
* Wire colors shown above may not agree with your LAN cable specification. Ask your LAN cable manufacturer for the latest specification.
3) Insert the aligned wires into a modular plug.
Figure 19. LAN cable insertion into a modular plug
Pin assignment of the modular plug in Fig. 19 is the image when the contacts and the cable stopper of the modular plug are
viewed from above.
Before inserting the wires into the modular plug, even out the length using a nipper. Note that the modular plug may not be
crimped on wires if the wires without the outer sheath are too long.
4) Crimp the modular plug using a crimper. Insert the wires into the modular plug so that the contacts of the modular plug stick
into the wires after crimping. Crimped modular plug is secured on the LAN cable by the cable stopper of the modular plug.
Check the contacts and the cable stopper when crimping the modular plug.
5) Follow 1) to 4) for the other end of the LAN cable.
6) Check continuity of the LAN cable. Modular cable tester (Part No. DY7206A0000) facilitates the continuity check. At the
same time, make sure that the wires are aligned in the specified order, the modular plug contacts stick into the wires, and
that there is no cable damage or disconnection.
7) Connect the modular plugs to the modular jacks.
After successfully finishing the continuity check, insert a modular plug of the LAN cable into the modular jack of Infilex VC
and the other modular plug into the modular jack provided for connecting to the user terminal/Pt100 temperature sensor.
Insert a modular plug until it clicks and gently pull the cable to check complete connection.

2) Splice the two wires (side B) of Part No. DY7221A and the wires from the Pt1000 temperature sensor with insulation
sleeves.
Note:
* The Pt1000 temperature sensor is a two-wire sensor. Because wire resistance causes measuring error, longer cable, which has larger wire
resistance, will cause greater measuring error. Use Part No. DY7221A (0.1–1.0 m long), and extend the sensor cable (1.25–2.5 mm

size)
if needed.
BACnet MS/TP network wiring
Daisy-chain Infilex VC as follows. Be sure to terminate the both ends of the BACnet MS/TP network with 120 Ωterminators.
The maximum wiring length of one network segment is 1200 m. Use the cable explained in the Input/output specifications
section.
