Introduction
This manual provides basic information that allows the control of the Daikin Modular-Light Air Handling
Unit (AHU). AHUs are used for air conditioning and air handling in terms of temperature, humidity and CO
2
level control.
There are two types of Modular-Light AHU, based on the direction of supply air flow of the main module
seen from the electrical panel, namely “Right-Hand Side” and “Left-Hand Side” layouts. The coils used to
produce cooling or heating are installed in separate modules.
