Supervision and control
1.1 The program
This air handling unit is managed by its PLC. In addition to its control functions, it also monitors and detects any faults
with the air handling unit.
The HMI terminal displays the following data which can be edited at any time:
- Values of connected sensors
- Unit on/off cycles
- Calibration of the sensors
- Detection of alarms and log of the last 100 alarms
- Password-protected configuration and operating parameters
- Device running times and time delays
- Management of time programs (4 daily, 4 weekly and 4 yearly programs)
- Language selected (French, English, German, Italian, Spanish, Dutch)
The connection with the pLAN network allows the program to use a terminal mounted on the front of the AHU and/or a
wall-mounted terminal installed in the room to be air conditioned.
IMPORTANT: To avoid any problems, the password must be known only by qualified personnel.
1.2 The HMI terminal
The terminal provided is equipped with a remote LCD display (8 lines x 22 columns) on the outside of the unit, which
has 6 keys (connected with a phone cable). It allows all of the program operations to be carried out. The terminal
displays the unit's operating conditions at any point in time and allows the parameters to be modified; in addition, it
can be disconnected from the main board as its presence is not strictly required.
