1 - MONITORING AND REGULATION
1.1 Controller
Each air heater is managed by the controller. In addition to its control functions, it also monitors and detects any faults with the
air handling unit.
IMPORTANT: To avoid any problems, the password must be known only by qualified personnel.
1.2 The pLDPRO terminal
The terminal is supplied equipped with an LCD screen (8 lines x 22 characters) with six control keys. It is installed on the front
of the unit's electrical box. 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.
The pLDPRO terminal displays the following data:
- Values of connected sensors
- Unit on/off cycles
- Calibration of the sensors
- Fault detection
- The password-protected configuration and operating parameters
- Device running times and time delays
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.

2 - CONFIGURING THE CONTROLLER
The controller and display must be configured before the unit is commissioned.
2.1 Configuring with master HEE Mono Boxes only:
The value of the display's factory-set address is '32'. It is pointless to only change it in the master HEE Mono Box.
If the nn field is set to '0', the terminal will use the Point-to-Point Protocol (not the pLAN) to communicate with the controller and
the “I/O Board address: xx” field will disappear as it will not be necessary.
It is however essential to assign a controller to the pLDPRO display by giving it an address (I/O Board address):
● Power up the master HEE Mono Box
● To switch to configuration mode, simultaneously press the ,  and keys for approx. 5 seconds; the page shown below
will be displayed, with the cursor flashing in the top left corner:
Terminal config
Press Enter
To continue
● To change the controller address (I/O Board address) press  twice: the cursor will move to the (--) field.
●using the  key, select the value 01, and confirm by pressing the  key again. If the value selected is different from that
stored previously, the page for the following figure is displayed and the new value will be stored in the terminal's permanent
memory.
Display address
Setting ……………. : 32
I/O Board address : --
●Press  again.
P:01 Adr Priv/Shared
Trm1 32 Pr
Trm2 None --
Trm3 None -- Ok?No
● Set Trm1 to 32 by pressing , press  .
● Set value 'Pr' (Private) to 'Sh' (Shared) by pressing , press  .
● Go to 'No' by pressing  several times, select 'Yes' by pressing then  .
The controller now has the correct address in Master mode only.

2.2 Configuring with slave HEE Mono Boxes only:
To configure the various slaves, the pLDPRO terminal must be removed from the master unit and connected to the slave units.
a) For the first slave:
● Power up the Slave HEE Mono Box
● To switch to configuration mode, simultaneously press the ,  and keys for approx. 5 seconds; the page shown below
will be displayed, with the cursor flashing in the top left corner:
Display address
Setting……………… : 32
I/O Board address : --
●Press  .
● Change the Display address setting from 32 to 00 by pressing , then press  .
Terminal config
Press Enter
To continue
● Switch off the Slave HEE Mono Box.
● Switch it back on again and then immediately press and for approx. 15 seconds.
pLan address : 1
UP: increase
DOWN: decrease
ENTER: save & exit
● Change the pLan address to 2 by pressing , then press  .
If there are no other Slave HEE Mono Box(es), go to step c), otherwise go to step b) to configure the other Slave HEE
Mono Box(es).
b) For the second Slave HEE Mono Box:
●Connect the pLDPRO to the slave to be configured
● Power up the Slave HEE Mono Box concerned and immediately press on and for approx. 15 seconds
pLan address : 1
UP: increase
DOWN: decrease
ENTER: save & exit
● Change the pLan address to 3 by pressing , then press  .
If you have other Slave HEE Mono Boxes to connect, simply adjust point b) by increasing the pLan address by 1 each time
(e.g. 3rd slave: pLan address 4, 4th slave: pLan address 5, etc.).

c) Assigning pLDPRO/Master HEE Mono Box display links:
● Connect the display to the Master HEE Mono Box

EN-9 1-PH HEE BOX

The Slave EC Box/display connection no. 1 has been made, if there are other slave boxes to be configured, repeat point d) by
increasing the I/O Board address by 1 each time (e.g. for the 2nd slave: I/O Board address 3; for the 3rd slave: I/O Board address
4, etc.).
The address configuration for the boxes and display is now complete; you can now refit the pLDPRO display on the Master HEE
Mono Box and connect the master/slave boxes by connecting the terminals.
2.3 State of the pLAN
When the system starts up, the pLAN network may encounter a number of problems (card fault and terminal start-up) caused by
incorrect connections or a wrong address. The state of the pLAN network can be displayed in real time on a special mask in order
to identify which devices (controller or terminal) are correctly connected and addressed.
To display the special page, press  and simultaneously for at least 10 seconds. After the first 5 seconds, a page is
displayed; after 5 more seconds, the next page appears:
NetSTAT Term : 17
Press Enter to quit
Once on the screen, network addresses 1 to 32 are displayed. The small rectangles represent the terminals and the large
rectangles , the controllers. If symbols appear then disappear, the pLAN may be unstable or, more likely, two components share
the same address. The number after Term indicates the address of the terminal used. The example shows that the network is
made up of 3 controllers with the addresses 1, 2, 25 and 4 terminals with the addresses 3, 4, 15 and 26. Once the page has been
verified, turn off the power, check the connections and addresses, then turn the power back on.
3 - MANAGING A NETWORK OF MULTIPLE CONTROLLERS
The pLAN network is the name of the physical network that links controllers to remote HMI terminals
pLAN = personal Local Area Network
The connection of the controllers via the pLAN network allows the datapoints of one controller to be exchanged for another,
following the logic set out by the program, i.e. the direction that these datapoints must follow and that from which they come. As a
consequence, they are not programmed by the user, who must only carry out the electrical connection.
3.1 pLAN electrical connections
3.1.1 Connecting controllers to the pLAN
The electrical connection between the controllers under the pLAN network (RS485) is carried out using an AWG20/22 shielded
cable composed of a twisted pair and a shield. The cards must be connected in parallel using the J7 or J8 connector.
The first and last controller must be no more than 500 m apart.
