Control (2/2)
Optimum
temperature control
of supply air*
1
Controls the supply air temperature of the air
conditioning unit at the optimum level to provide
comfort and to save energy.
- One Infilex ZM controls up to 4 groups.
-
AHU controller and Infilex ZM must be
connected to the same NC-bus line.
Mixing loss control*
1
Sets the difference between the set temperature of
the perimeter air conditioning unit and the interior air
conditioning unit that are interlocked. This prevents
the mixing loss.
- One (group of) Infilex VC interlocks
with another (group of) Infilex VC
and/or Infilex FC.
- Slave Infilex VC and/or Infilex FC can
not interlock with a different Infilex VC
and/or Infilex FC.
- Do not operate the slave Infilex VC
and/or Infilex FC with the user terminal.
Parallel operation of
multiple VAV*
1
Concurrently turns on/off the multiple VAV units or
changes fan speed of the multiple VAV units (supply
air VAV unit and return air VAV unit).
- One-to-one Infilex VC or one-to-
multiple Infilex VC are interlocked.
- For the parallel operation, Infilex VC
must be connected to the same
SC-bus line.
Fan powered control Turns on/off the fan of the VAV unit with fan to
maintain enough airflow.
Fan output corresponds with heating/
cooling conditions and each fan type.
- Series fan:
Fan is ON when VAV unit is ON.
- Parallel fan (for temperature):
Fan is ON when VAV unit is ON in
heating mode.
- Parallel fan (for air volume):
Fan is ON when VAV unit is ON in
heating mode with low airflow.
Reheat control*
1
Enables the heating mode by electric heater or hot
water valve.
- Electric heater and ON/OFF valve
allow up to two-position control.
Floating valve allows single-position
control.
- Reheat control is forcibly performed by
operating the BMS client PC (manual
override function).
Monitoring (with the
BMS client PC)
Individual
monitoring*
1
Monitors and controls the point data (measuring,
setting, operation, and control data) of Infilex VC
from the BMS client PC.
The following are examples of the point data for
individual monitoring:
VAV ON/OFF, VAV failure, room temperature, cool
setting/main setting, heat setting, heat high limit/set
high limit, cool low limit/set low limit, setback,
reheater output, fan output, measured air volume,
max. air volume, damper position
(Not all of the items above are required to monitor or
control with the client PC.)
Group monitoring*
1
Forms a group of multiple Infilex VC, monitors and
controls the following point data of the grouped
Infilex VC through the BMS client PC:
VAV ON/OFF, VAV failure, room temperature*
3
, cool
setting/main setting, heat setting, heat high limit/set
high limit, cool low limit/set low limit, setback
(Not all of the items above are required to monitor or
control with the client PC.)
- All of Infilex VC connected from a
single Infilex ZM are divided into up to
25 groups. (Various grouping is
available.)
- The point data for the group monitoring
can not be individually monitored.
- Both of the group monitoring and the
individual monitoring can be applied to
the grouped Infilex VC. (e.g., VAV
ON/OFF for group monitoring and
room temperature for individual
monitoring)
Batch operation*
1
Forcibly sets the airflow of all the VAV units (that are
included in each air conditioning unit group) at the
maximum or minimum volume by operating the BMS
client PC.
- One Infilex ZM controls up to four
groups.
- Batch operation is enabled with Infilex
ZM as well as with the BMS client PC.
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.
*3 Room temperature for the group monitoring calculates either the average value in a group or the representative value of a group
.
