Remarks
Control
(common to valve
ON/OFF control and
valve proportional
control types)
Parallel operation
of multiple FCUs:
fan start/stop, valve
open/close, and fan
speed changeover*
Fan start/stop, valve open/close, or fan speed
changeover of multiple FCUs is concurrently
operated.
Master- and slave- Infilex FC must have
the same fan output type and must be
connected to the same LS-bus.
When the fan speed is set to AUTO, do
not turn off Infilex FC with temperature
control.
Do not operate the user terminal(s)
connected to the slave- Infilex FC.
Operation with a user
terminal
(common to valve
ON/OFF control and
valve proportional
control types)
FCU start/stop
operation
FCU is turned on/off with a user terminal.
The latest start/stop operation with a
user terminal or with the center unit
takes priority.
4)
Start/stop operation with a user terminal
can be restricted by the center unit.
Setback operation is not available when
the start/stop operation is active.
Temperature
setting
Set temperature is changed with a user terminal.
The latest temperature setting with a
user terminal or with the center unit
takes priority.
5)
High/low limit setpoint can be set with
the center unit.
Dual setting is available
6)
.
Setback operation FCU operation is switched to setback operation with
a user terminal.
The latest setback operation with a user
terminal or with the center unit takes
priority
5)
.
Setback operation can be restricted by
the center unit.
FCU start/stop operation is not available
when the setback operation is active.
Fan speed control
Fan speed is changed over (L/M/H/AUTO) with a
user terminal.
The latest changeover operation with a
user terminal or with the center unit
takes priority
5)
.
Operation with the
center unit
Individual
monitoring*
The following items are monitored and controlled by
the center unit:
FCU start/stop, temperature measuring,
temperature setting, high/low limit setting, setback
difference, fan speed control, valve position,
cooling/heating conditions, control status
7)
(Not all the items above are required to centrally
monitor or control.)
Group monitoring* Multiple Infilex FC are divided into groups, and with
the center unit, the following items can be monitored
and controlled per grouped Infilex FC:
FCU start/stop, temperature measuring
8)
,
temperature setting, high/low limit setting, setback
difference
(Not all the items above are required to centrally
monitor or control.)
All the Infilex FC connected from a
certain Infilex ZM can be divided into up
to 25 groups. (Various grouping is
available.)
Any item set for group monitoring can
not be individually monitored.
Group monitoring and individual
monitoring can be combined (e.g. FCU
start/stop for group monitoring and
temperature measuring for individual
monitoring).
One Infilex FC can belong to only one
group.
Batch operation*
All valves can forcibly be opened/closed with the
center unit.
This facilitates pipe flushing.
Valves controlled by all the Infilex FC
connected from a certain Infilex ZM are
subject to batch operation.
Batch operation can be performed with
Infilex ZM as well as with the center unit.
