1GENERALITIES
1.1 Description
The climatic modules of the c-pro 3 CLIMA sistema series are devices studied for the air conditioning and the heating
of buildings.
They make use of the programmable controllers belonging to the c-pro 3 series and of the user interfaces belonging
to the same series.
They are available in built-in and in blind version with remote user interface (according to the kind of module).
They can be powered both in alternating and in direct current (24 VAC/20... 40 VDC).
The modules allow realizing an expandable and modular control device network distributed in the main rooms of the
building reducing the wiring work to a minimum: the modules c-pro 3 hecto MCCT and c-pro 3 mega MCCT can
manage the thermal power plant, the c-pro 3 hecto MCZN ones the air conditioning and the heating of two zones
instead, the c-pro 3 hecto MCDE ones the dehumidifiers and the c-pro 3 hecto MCPS ones finally the thermal solar
panels.
Through the user interfaces it is possible to operate (with different modalities to access to the functions) on the
modules c-pro 3 hecto MCZN.
Some of them incorporate a temperature sensor or a temperature and humidity sensor (according to the model).
The user interfaces can easily be integrated in residential and commercial rooms (at the front of the interfaces it is
possible to apply the plates CPVP or the plates belonging to the series “Living” and to the series “Light” Bticino).
All the modules have communication ports (programming, CAN, S-485, with MODBUS communication protocol, etc.).
Through the programming port it is possible to make the upload and the download of the configuration parameters
(using the programming key EVKEY10); through the S-485 one, with MODBUS communication protocol, it is possible
to connect the devices to the set-up software system Parameters Manager or to the plants monitoring and supervision
one ICS (through a serial interface) instead.
Through the CAN communication port it is possible to connect the devices among them; through the use of the module
c-pro 3 mega MCCT it is finally possible to integrate the devices in systems using the BACnet MS/TP communication
protocol.

As highlighted in the previous table, the controllers are set by default to be automatically recognised in network as:
•thermal power plant regulator CANbus 1 address
•zone 1 regulator CANbus 2 address
•regulator for dehumidifiers
added, associated to zone 1 regulator CANbus 22 address
•regulator for solar panels CANbus 17 address

3.4.1 MCCT thermal power plant controller network configuration
As the thermal power plant controller is the logical centre of the system controlled, it is first necessary to set how
many MCZN zone regulators will be present in the system, following the procedure given below:
1. Enter the Installer  General parameters menu of the MCCT regulator
2. Set the total number of zones controlled and the number of MCZN zone regulators present in the system
3. To set the communication speed (125k suggested) go to the menu
Installer -> general parameters and modify the baud rate parameter.
3.4.2 MCZN zone controllers network configuration
The zone regulator leaves the factory configured as zone 1 regulator (therefore with CANbus 2 address).
Whenever it is necessary to install more than one zone controller in the system, it will be necessary to configure the
regulators present as zone regulators 2, 3, etc…up to a maximum of 8.
To change the network configuration of the MCZN zone controller network, follow the procedure below:
1. Connect a zone regulator to the CANbus network (leaving all of the other zone regulators disconnected from
the network);the controller connected will be recognised as zone 1 controller
2. Access the MCZN zone regulator application as shown in chapter 5.2.1
3. Enter the Installer  General parameters menu
4. Set the number of local zones managed by the MCZN regulator (1 or 2 local zones)
5. Set the number of the last zone regulator that is to be inserted in the system managed (e.g. zone 4 regulator).
6. The controller will automatically assume the appropriate CANbus address (address 25 for the regulator of zone
4)
7. epeat the operation, connecting the next to last zone controller to the CANbus network and so on, until the
first zone regulator is connected (zone 1 regulator).
