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.

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.

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.
