I WARNINGS
• To be able to monitor the HCC Touch Panel from remote using
a VNC program, it is necessary that your house is provided
with internet access and that the Touch HCC panel is physically
connected via a network cable to the router or home switch.
• To congure the home network, you must have at least a basic
understanding of some data net skills.
• In the context of the preparaon of the network, the external
IP address of the home can be of 4 dierent types.
A) Public stac IP
B) Public dynamic IP
C) Private dynamic IP
D) Private dynamic IP
How to proceed:
In case A: you need to forward ports from public IP to local
private IP acng on the router’s NAT rules, VNC service
standard port TCP 5900, service port 8000
IncaseB: as A, you also you need to congure the router to
get an account for a dynamic dns server, so that each me you
connect, the router associate the domain name chosen with
the dynamic IP address assigned by the provider.
IncaseCandD: you must purchase a scratch card that enables
“Easy Access”, once enabled lasts for the life of the panel, and
allows access with a special PC and Smartphone client without
further conguraon, only entering username and password
for easy access.
NotesontheplantpreparaonforHCC
The HCC devices require power as follows:
panel 24Vdc 700mA
I/O FLOOR 24Vdc 1A
ROOM 24Vdc 200mAper
sensor
Then prepare the power supply of adequate power to support the
system, or use HCC POW.
MODBUS cable: Templari HCC cable (similar Belden
3105A 2x22AWG shielded)
Power cable: 2x1 mmq
Power supply: HCC POW 24Vdc, 2.5A
Prepare the electrical system for the passage of cable ducts by at
least 16 mm in diameter for the passage of only MODBUS cable and
power supply for sensors and devices.
Modbus connecon
WARNING!
We recommend using the HCC CABLE data cable
The connecons between the BMS board mounted on the machine
and the dierent devices (Touch Panel HCC, HCC ROOM sensor, HCC
FLOOR board) must comply with the connecons shown in Tab1 and
Figure 1.
The HCC system can also be connected to the PLan network of the
µPC as shown in Figure 6.

Installaon Note: MODBUS data cabling should not ever be done
with direct branches that form Y or stars.
The connecon between a device and the next must take place via
“concatenated” connecons, connecng in sequence the sensors
and MODBUS devices. It is therefore convenient to prepare the
ng of cables for the passage of 2 MODBUS data cables; the rst
intended for the device in queson and the second will be the return
to connect the next device.
Each cable duct which ends on a sensor will then have at its inner
3 wirings:
2 MODBUS cables (one that comes inside plus one going out), plus
one power supply consists of 2 wires 2x1
An excepon is the 2-terminal devices (usually, the heat pump and
the HCC panel) which instead will have a single MODBUS cable and
one power supply.
• For Data cable less than 10 meters long, use only one 120
Ohm terminaon resistor, the one onboard the BMS or the
one on the last chain peripheral.
• To use the HCC system remotely, via a VNC program, you must
connect the RJ45 port on the back of the Touch HCC Panel to
a Router or Switch via an Ethernet cable.
WARNING!
The MODUS network must always terminate at the ends with a
120 Ω resistor, between terminals A and B. Usually the network
terminaons are on the one hand the HCC panel and on the other
the heat pump. In some conguraons the heat pump may not be
presents, and then the other extreme of the network will have a
MODBUS device (sensor or Floor board), which must have a 120 Ω
resistore between the terminals A and B.
Devices inializaon
Eachdevicemustabsolutelyhaveauniqueaddress.
ROOM sensors:
For ROOM sensors see chapter II.
I/OFLOORboards:
At rst power on, each FLOOR board has a default address of 222.
To set the address of each FLOOR board, these must be connected
oneatame via the MODBUS cable to the HCC network. To change
the address of the virgin board see paragraph 4.3.2. To permanently
set the address you need to power o the FLOOR board. The board
should then be set as installed (see 4.3 Installer) and as acve (see
4.2 Advanced).
