Air volume control technical manual
Indoor unit air volume can be controlled with a opening-closing of a damper by either an analog input (CN2A) or a
contact input (CN105) to the air conditioning unit.
With the PEAD series, it is possible to cut energy consumption by controlling not only the air volume but also the
compressor capacity.
■Corresponding model
Air volume can be controlled with the following models.
(1) PEAD-RP60,71,100,125,140JA(L)
(2) PEFY-P63,71,80,100,125,140VMA(L)-E
NOTE:
Air volume control with analog input 0-10V is not available with the following models.
(a) PEAD-RP35,50JA(L)
(b) PEFY-P20,25,32,40,50VMA(L)-E

the damper system controller supplied on site.

*Air volume rate shows the value without change in
the external static pressure. For values in different
external static pressure, refer to 3. Fan characteristic
curves for details.
1-2. Outdoor unit capacity control
With the PEAD series, compressor capacity is controlled in accordance with air volume level in 10
stages from V1 to V10.
With the PEFY series, compressor capacity will not be controlled because numbers of indoor units are
connected. However, it is possible to reduce energy consumption with a change in the air volume
leading to compressor capacity control due to a change in condensing temperature.

■Condition:
1. R1- R4 indicates the air outlet of each indoor unit.
2. R4 fully open at all times.
3. Air volume designed as R1: 5m3/min, R2: 5m3/min, R3: 7m3/min, R4:17m3/min.
4. Rated air volume measured when R1 - R3 is fully open. (External static pressure set as 100Pa)

■Selecting air volume stage V1~V10
Depending on the damper opening pattern R1-R3, patterns 1~8as in the below chart is available. The air volume
stage is selected from the fan characteristic curve. (Refer to [Fig. 1-4-3])
Choose the pattern closest to the required air volume and which the diagram exceeds.
Duct pressure drop depends on the site conditions. Shown here are temporarily numbers in case of external static
pressure 100Pa.

2. Cooling/ Heating/ Fan mode
3. Air volume rate change (Hi-Mid-Lo)
PRECAUTION:
Multistage air volume control is not available via MAC-397IF-E.

available one at a time because setting is made by switching DIP-SW of MAC-397IF-E. Refer to the MAC-397IF-E manual for DIP-SW setting and
wiring.

Check air volume at each air outlet when R1-R4 is full open and set static pressure as target value. Then, analog
input to keep the static pressure at this target value even when either of the damper closes.
With MAC-397IF-E as in section 2-2, it is also possible to stop the indoor unit when all duct damper closes.
*Refer to the 1-3 for air volume differentials to prevent hunting.

Damper system controller setting will be prioritized. Set function on a damper system controller.
Also, settings and error codes set by a remote controller will not be reected to the damper system controller.
Signal priority: Damper System remote controller > (analog input) > ME or MA remote controller
* Analog input: only air volume control will be effected
Function Model Restrictions Cause / status
Operation mode
PEFY *1
If there are cooling/heating simultaneous
operation set from damper system
controller in a system of Y series outdoor
unit + multiple indoor unit, damper system
remote controller will display operation
mode but indoor fan may stop.
Indoor unit fan will stop when a different mode from outdoor unit
operation mode is selected.
PEFY *1 Operation mode cannot be controlled with
M-NET system controller. If an operation mode is prohibited, operation mode will be displayed, but indoor unit will operate in FAN mode.
Analog input PEAD Do not combine level input of indoor unit
ON/OFF and IT transmission. Level input is prioritized and damper system controller input will be invalid.
Error
PEAD Transmission error cannot be detected when the IT transmission line is cutoff or
the connector is not plugged in.
After the IT transmission line cut is xed or the connector is
plugged in, CN105 will automatically recover. If indoor units
cannot be controlled from damper system remote controller,
check the IT transmission line or the connector.
PEAD *1 Indoor unit error code will not be displayed
on damper system remote controller.
Indoor unit error will be notied by CN105 transmission. To
check error code when in service, setting of MA or ME remote
controller is recommended.
Prohibition PEAD ON/OFF control from damper system
remote controller is not available when
ON/OFF operation is prohibited from
system remote controller.
Because operation prohibition will be prioritized, setting at
damper system controller will be invalid. Do not combine ON/
OFF prohibition and IT transmission.
Model PEAD
PEFY Damper system setting is not available for
models PEAD-RP35, 50JA(L), PEFY-P20,
25, 32, 40, 50VMA(L)-E. For these models, air volume will not change with damper
system setting.
Damper
specication PEAD *2
Use bypass damper to prevent rapid
change in external static pressure. If
bypass damper is not available, set a
delay timer circuit which starts the damper
in 1 minute after receiving damper system
input to indoor unit.
In heating, to protect the unit, unit may stop due to high pressure
error. When bypass damper is not used, as shown in the
below gure, operation range will be limited depending on inlet
temperature.
*1 Check operation. No restrictions in functions when 0-10V analog input is connected on its own.
*2 Refer to the below diagram of operation temperature range when bypass damper is not available and when there is no damper delay
operation.
Operation temperature range:
To protect unit, there are restrictions when bypass damper is not available and when there is no damper delay
operation for 1 minute. The restriction will depend on piping length and air inlet temperature.

being applied to the power supply terminal connector. Use a
cable tie to secure the cable.
