Description
Remarks
Operation (common to
valve ON/OFF control
and valve proportional
control types)
FCU start/stop
operation
FCU is turned on/off with the center unit, DI, or a
user terminal.
Each Infilex FC can individually be
started up and shut down.
Setback operation Set temperature is changed to save energy.
Each Infilex FC can individually control
the setback operation..
FCU interlocking
with OAHU*
Infilex ZM can configure the sets composed of
Infilex FC and AHU controller. (Multiple Infilex FC
and AHU controllers can be included in a set.) In a
specified set, all the FCUs interlock with the OAHU
start/stop operation.
One Infilex ZM can control up to 4 sets.
‘OAHU interlocking with FCU’ is not
available when ‘FCU interlocking with
OAHU’ is active.
Do not operate the user terminal(s) to
start/stop Infilex FC.
OAHU interlocking
with FCU*
Infilex ZM can configure the sets composed of
Infilex FC and AHU controller. (Multiple Infilex FC
and AHU controllers can be included in a set.) In a
specified set, all the OAHUs interlock with FCU
start/stop operation if at least one FCU is started
up.
One Infilex ZM can control up to 4 sets.
‘FCU interlocking with OAHU’ is not
available when ‘OAHU interlocking with
FCU’ is active.
Control
(for valve ON/OFF
control type)
Temperature
control
1)
Valve is ON/OFF-controlled so that the actual
(measured) temperature matches the preset
temperature.
Fan speed control
The fan speed is multistage-controlled depending
on the difference between the actual temperature
and the preset temperature. Fan multistage control
has L/M/H(low/medium/high) type or L/M/H/OFF
type.
Fan speed is automatically controlled
when it is set to AUTO.
When L/M/H is selected, the selected fan
speed is output.
Control
(for valve proportional
control type)
Temperature
control
1)
Floating valve is PID-controlled so that the actual
(measured) temperature matches the preset
temperature.
Noise control
To prevent the water flushing noise, the valve is
completely closed when its closing position
reaches the specified.degree.
Fan speed control
The fan speed is multistage-controlled depending
on the difference between the actual temperature
and the preset temperature.
Fan multi-stage control has L/M/H type or
L/M/H/Off type.
Water- or fan speed-priority control can be selected
in response to the applications.
2)
Fan speed is automatically controlled
when it is set to AUTO.
When L/M/H is selected, the selected fan
speed is output.
Control
(common to valve
ON/OFF control and
valve proportional
control types)
Cooling/heating
changeover*
The following items are sent from the center unit
when cooling/heating changeover is required:
Cooling available, heating available, cooling and
heating available, fan only (cooling or heating not
available).
Infilex ZM can configure the sets
composed of Infilex FC. One Infilex ZM
can control up to 8 sets for the
cooling/heating changeover.
Mixing loss control* Indoor perimeter- and interior- FCU/VAV are
interlocked, and mixing loss is controlled with the
deviation between the preset temperature of the
indoor perimeter- and the interior- FCU/VAV.
One (group of) Infilex FC can interlock
with another/other Infilex FC and/or
Infilex VC. Interlocked Infilex FC and/or
Infilex VC cannot interlock with different
Infilex FC and/or Infilex VC.
Do not operate the user terminal(s)
connected to the interlocked Infilex FC
and/or Infilex VC.
Optimum
temperature control
of OAHU supply air
The OAHU supply air is set at optimum
temperature in response to FCU load. This
enables comfortable temperature and OAHU fan
power cutback.
Infilex ZM can configure the sets
composed of Infilex FC and AHU
controller. One Infilex ZM can control up
to 4 sets.
VWV/VWT
control*
, 3)
Pump feed power is cut back by adequately
controlling supply water pump in response to FCU
load. Additionally, chiller operating efficiency is
enhanced by setting the optimum chiller outlet
temperature.
Infilex ZM can configure the sets
composed of Infilex FC and pump
controller. One Infilex ZM can control up
to 4 sets.
