This commissioning guide provides valuable information when commissioning an ACH-3000 air
handling unit at the factory. After the air handling unit is installed in the building, the installer and/or
system integrator will also find essential information in this guide to get the air handling unit to work
ideally and provide maximum comfort with minimum energy consumption.
It is crucial that anyone who is in contact with the ACH-3000 system, – manufacturers, installers,
service technicians and system integrators – must read this commissioning guide thoroughly before
starting to commission the AHC-3000.
For the manufacturer
The AHC-3000 has been developed with the aim of making the AHU controller set-up as easy and
user-friendly as possible. The AHC-3000 has a number of pre-configured most frequently used AHU
applications. The configuration and settings are simple and easy to make using the hand-held HMI
display.
For the commissioning engineer
Commissioning, setting the operation schedulers and optimising the energy of the AHC-3000 on-
site is done very easily from the HMI touch display.
For the installer
For the installer on-site, all internal cabling, wiring and configurations have already been made at the
factor. Therefore, all you need to do is supply the AHC-3000 AHU with power.
For the system integrator
The OJ AHC-3000 is one of the most flexible systems on the market in terms of BMS system
integration. Standard features worth mentioning: The Modbus RTU & TCP/IP is built-in. The
associated protocols can be downloaded from www.ojelectronics.com.
For the service technician
On the AHC-3000-T, all service settings and software updates can be done from a smartphone.
For the user
The AHC-3000 has several interfaces, such as: OJ-Cloud, Bluetooth, AHC-3000 app, HMI-20T room
touch display and the HMI-35 touch display from where the daily user can change temperature and
operation settings and receive alarms. Basic settings are password protected.
