Overview
Infilex FC Model WY5205W is a DDC controller for FCU. In
addition to FCU ON/OFF operation, valve control, and fan
speed changeover, Infilex FC provides advanced controls
such as setback and interlock operations with OAHU.
Infilex FC in combination with room user terminal(s) allows
room occupants to operate FCU.
Infilex FC also communicates to our BMS. This enables to
centrally monitor and control the scheduled operation,
operating status, and temperature measurement of FCU.
BMS: Building management system
DDC: Direct digital control
FCU: Fan coil unit
OAHU: Outdoor air handling unit
Features
●
Compact size:
Small sized body fits inside an FCU.
●
Two kinds of FCU control:
Valve ON/OFF control and valve proportional control for
FCU are available.
●
Advanced controls in combination with our BMS:
Infilex FC combined with our BMS allows FCU to
interlock with OAHU and to control mixing loss between
perimeter and interior zones.
●
Standalone control:
Infilex FC is not only connected to our BMS but also used
as a standalone controller.

●
Room user terminals:
Our user terminal (Neopanel or Neoplate) is connectable
to Infilex FC, allowing the room occupants to turn on/off
FCU and change temperature setting.
●
Easy installation:
Screwless push-in terminals (for pipe temperature
sensor input, DI, FCU ON/OFF output, and control valve
output) and modular jacks (for communication, user
terminal connection, and temperature sensor input)
reduce wiring workload.
