Operation
VAV ON/OFF
Turns on/ off the variable air volume (VAV) unit by
operating the BMS client PC or the user terminal.
- Each Infilex VC can individually turn
on/off the VAV unit.
- The latest user terminal/BMS client PC
operation is effective.
- VAV ON/OFF function using the user
terminal can be disabled by the BMS
client PC.
- Once
VAV ON/OFF
function is set, you
can not turn on the
Setback
function with
the user terminal. (The user terminal
allows you to operate either
VAV
ON/OFF
or
VAV ON/Setback ON
.)
Setback
Adds/Subtracts the setback value to/from the set
temperature.
Changes the set temperature by operating the
BMS client PC or the user terminal.
The setback value is preset at Infilex VC.
- Each Infilex VC can individually change
the set temperature for the
setback
operation.
- The latest user terminal/BMS client PC
operation is effective.
- Setback function using the user terminal
can be disabled by the BMS client PC.
- Once
Setback
function is set, you can
not turn off the VAV unit with the user
terminal. (The user terminal allows you
to operate either
VAV ON/Setback ON
or
VAV ON/OFF
.)
Temperature setting Changes the set temperature by operating the
BMS client PC or the user terminal.
- The latest user terminal/BMS client PC
operation is effective.
- High/low limit of the setpoint is set by the
BMS client PC.
- Dual setting is available*

.
VAV interlocking
with air conditioning
unit*
1
Interlocks the ON/OFF operations of the VAV units
with those of the air conditioning units.
- One Infilex ZM controls up to 4 AHU
groups.
- Do not operate
VAV ON/OFF
with the
user terminal when you set the
VAV
interlocking with air conditioning unit
function.
- Do not set the
air conditioning unit
interlocking with VAV
function when you
set the
VAV interlocking with air
conditioning unit
function.
Air conditioning unit
interlocking with
VAV*
1
Interlocks the ON/OFF operations of the air
conditioning units with those of the VAV units.
- One Infilex ZM controls up to 4 groups.
- Do not set the
VAV interlocking with air
conditioning unit
function when you set
the
air conditioning unit interlocking with
VAV
function.
Control (1/2)
Temperature control Controls VAV damper to meet the actual
(measured) temperature with the set temperature.
Each Infilex VC can individually controls
the VAV damper.
Fan speed control*
1
Detects over/short static pressure of the VAV unit
and optimally controls the revolution speed of the
supply air fan to minimize the fan power.
- One Infilex ZM controls up to 4 groups.
- AHU controller and Infilex ZM must be
connected to the same NC-bus line.
AHU: Air handling unit
BMS: Building management system
VAV: Variable air volume
Notes:
*1 These functions are enabled by Infilex VC being combined with Infilex ZM and integrated in our BMS.
*2 Dual setting is the method to have cooling setting and heating setting separately.
