13 K-Touch Panel
13.1 Warnings
To be able to monitor the panel remotely using a VNC program, it
is necessary that the house is equipped with internet access, and
that the HCC Touch panel is physically connected via a network
cable to the home router or switch.
The panel comes with the “Easy Access” function already
activated, which lasts for the life of the panel. This function
allows, using a specific client, to remotely access the panel
using a PC or a Smartphone without further configuration, only
by entering the user and password of the Easy Access account.
Access credentials are provided by email to the customer at the
time of activation. For this reason at the time of purchase it is
necessary to provide a valid email address where you will receive
all useful information.
NOTE!
13.2 Notes on the plant preparation for
K-Touch panel
The K-Touch panel may only be supplied with power via the
internal power supply of the machine, otherwise the guarantee
expires.
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 connection
WARNING!
We recommend using the HCC CABLE data cable
The connections between the BMS board mounted on the machine
and the K-Touch Panel must comply with the connections shown in
Tab1 and Figure 1.
The K-Touch Panel can also be connected to the PLan network of the
µPC as shown in Figure 6.
Connect the G (Ground) pole of the HCC Connect cable of the
K-Touch Panel to the shield of the Modbus data network.
Connect the ground terminal of the power supply to the shield of
the Modbus data network.
The shiels of the various cable sections, between the various
devices that may be present, must be connected in series and NOT
inserted in the G pole of each device, as in Figure2

Installation Note:
In case there are more devices, MODBUS data cabling should not
ever be done with direct branches that form Y or stars.
The connection between a device and the next must take place via
“concatenated” connections, connecting in sequence the sensors
and MODBUS devices. It is therefore convenient to prepare the
fitting of cables for the passage of 2 MODBUS data cables; the first
intended for the device in question 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 exception 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 termination 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 (LAN1) port on the back of the K-Touch
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
terminations are on the one hand the HCC panel and on the other
the heat pump.
