1 - MONITORING AND CONTROL

1.1 The program

Each 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:
. values of connected sensors
. unit on/off cycles
. calibration of the sensors
. detected alarms
. the password-protected configuration and operating parameters
. device running times and time delays
. management of time programs (4 daily, 4 weekly and 4 yearly programs)
. interface language (French and English)
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 an LCD screen (8 lines x 22 characters) installed on the front of the unit's electrics box,
which has 6 keys (connected with a phone cable). It allows all of the program operations to be carried out. The terminal can be
used to display the unit's operating conditions and change its parameters.
