Air Volume Control By Analog Input - Mitsubishi Electric Mr. SLIM PEAD-RP60JA Technical Manual

1. Air volume control by analog input

1-1. Air volume control
Indoor air volume can be controlled in 10 different stages from V1 to V10 with analog input 0-10V from
the damper system controller supplied on site.

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.

*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.
