1. Specifications

AHU-KIT-SP (AHU interface) is the controller dedicated to making the AHU system by using a split type outdoor unit.
AHU interface equips 0–10V and 4–20mA analog input as a basic capacity control method of the connected outdoor unit.
As an alternative control method, the setting temperature control can be used from the remote controller as well.
In addition, AHU interface can communicate over the Modbus protocol and it enables the capacity control (0–100%) or setting temperature control according to requirements.
For more details, please see the relevant sections.
