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 congure the home network, you must have at least a basic
understanding of some data net skills.
• In the context of the preparaon of the network, the external
IP address of the home can be of 4 dierent types.
A) Public stac 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 acng on the router’s NAT rules, VNC service
standard port TCP 5900, service port 8000
IncaseB: as A, you also you need to congure 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.
IncaseCandD: 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 conguraon, only entering username and password
for easy access.
NotesontheplantpreparaonforHCC
The HCC devices require power as follows:
panel 24Vdc 700mA
I/O FLOOR 24Vdc 1A
ROOM 24Vdc 200mAper
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 connecon
WARNING!
We recommend using the HCC CABLE data cable
The connecons between the BMS board mounted on the machine
and the dierent devices (Touch Panel HCC, HCC ROOM sensor, HCC
FLOOR board) must comply with the connecons 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.

Figure 1
Installaon Note: MODBUS data cabling should not ever be done
with direct branches that form Y or stars.
The connecon between a device and the next must take place via
“concatenated” connecons, connecng 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 queson 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 excepon 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 terminaon 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
terminaons are on the one hand the HCC panel and on the other
the heat pump. In some conguraons 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 inializaon
Eachdevicemustabsolutelyhaveauniqueaddress.
ROOM sensors:
For ROOM sensors see chapter II.
I/OFLOORboards:
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
oneatame 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 acve (see
4.2 Advanced).

WARNING!
If the plant is designed to directly connected the heat pump to a
oor system, such as underoor heang, without intermediate
systems, the absence of condensaon is not guaranteed.
ConnecngtotheKitaheatpump.
If you want to use the PGD1 remote control panel at the
same me as the Touch Panel HCC, you must use a BMS card,
purchased separately.
If the BMS card is present, a 120Ω resistore must be installed
at the both ends of MODBUS network. To enable the HCC to
funcon properly, set the communicaon protocol to MODBUS
RTU 485 via the PGD1 panel (mask Ge01).
Referring to the μPC, make sure you DONOT have the terminal
ID09 connected to GND as shown in Figure 5.
With this conguraon you can simultaneously use the PGD1
control panel and the Touch Panel HCC.
If the HCC touch panel is the only display present and it is
connected to the heat pump via the P-LAN port then it is
necessary that the ID9 contact of the µPC board is connected to
the Ground, as in gure 6.

1
The board has 8 relay dry contact NC NO outputs with which it is possible
to drive heads or circulators or devices that require a dry contact. All
relays are independent, usable at low or medium voltage, maximum 10A
230V.
The relays are independent of each other, controllable and programmable
(see 4.3.1 ROOM sensor sengs).
2
The card provides the control of a zone mixer, PWM or 3 points type.
Use the MIX output for digital valves with PWM control. Use the
PHASE OPEN and PHASE CLOSE outputs to connect a mixing valve with
3-point control (neutral, open phase, close phase). The 2 outputs work
synchronously and not independently.
3
The PWM signal can be connected to the CIRCULATOR connecon port
to control a zone circulator with PWM input.
4
Acquired temperatures are used to control the outlet and inlet
temperature of the plant (maximum ow temperature, moisture
temperature and anfreeze control). To idenfy the probes you need to
heat one, even just holding it in your hand, and see which values change
in the readings. Then you can install the probe in the proper housing.
To improve the probes performance, it is recommended to use a thermal
conducve paste.
WARNING!

You can now inspect all the sensors by checking the address stored in each one and, if necessary, modify it where it is needed
by using the keys of the HCC ROOM sensor.
Aer a minute of inacvity The display will turn o. Tapping the keys will turn it on again, making it possible to modify the
address.
Once the address seng phase of all sensors has ended, wait unl the display of the last updated sensor turns o. Remove the
24Vdc line voltage. This operaon allows the sensor to abilitate the newly set address.
• Connect the HCC Touch Panel power terminal
• Turn on the 24Vdc power line and go to: SETTINGS -> ADVANCED-BUILDER screen; proceed to the vericaon of the
addresses of each ROOM sensor, according to the address manually set to the corresponding sensor.
• Verify that the buon next to the address seed is selected, if it is physically connected with the Data network (see 4.3.1).
WARNING!
If FLOOR Mixing boards are present, make sure that all Room Sensors refer to the correct mixing zone, otherwise the zones will be
malfunconing.
• Go to: SETTINGS -> ADVANCED screen, to enable the installed and connected sensors (green dot selected), by selecng the
square corresponding to the installed ROOM sensors. The selected square will turn green and the sensor will be acve.
In the event of a malfuncon, check the data network connecons in Secon (Modbus Data Network Correcon).

III Modbusdatanetworkcheck
WARNING!
Before proceeding to check, make sure that the power supply to the 24Vdc line and to the power supply line of the electrothermal
actuators of the system have been disconnected.
In the event of malfuncons of the Modbus data network, check the connecons according to the following points:
• Make sure that the connecons between the BMS board, mounted on the machine, and the various peripherals (Touch HCC
panel, HCC ROOM sensor, HCC FLOOR board) respect the connecons shown in tab1, Fig1 and Fig2.
• Make sure that the Modbus data cable used is the recommended type.
• Make sure you have inserted the 120 Ω terminaon resistors, supplied with the Touch HCC Panel, and that you have connected
the sheath of the data cable to the ground pole of the power supply.
If the total wire length of the Modbus data line is less than 10 meters, use only one terminaon resistor, indierently, on the
BMS or on the last peripheral of the chain.
• Make sure there are no copper wires that short-circuit the A and B signals or the A and B signals with the braid.
To verify this use a Mulmeter in electrical connuity posion, or Ω scale, and make sure that there are no short circuits on
the Modbus data line. In Ohmic scale posion there will be an impedance of about 60 Ω in case there are both terminaon
resistors, or about 120 in case there is only one terminaon resistance.
• Check the electrical connuity of the plug-in terminal relave to the Modbus data line, and eventually replace it with a working
one.
IV First start
During the rst start of the panel, the product serial number is
requested. For correct operaon of all services it is necessary to
enter the correct serial number, which can be read on the back
of the panel or on the adhesive label on the box. Normally the
panel is supplied with the serial number already registered, but
aer an update it may be necessary to reinsert it, therefore it
is recommended, during maintenance, to always have the serial
number at hand.

1 INTRODUCTION
The HOUSE CLIMATE CONTROL monitors for the management of
home comfort is born with the aim to make the climate management
in your home as easy and intuive as possible.
Using the touch panel you can navigate the screens, separated
into 4 secons ENVIRONMENTS, HEAT PUMP, SET and SCHEDULE,
and through them you can govern every aspect useful for comfort
and scheduling according to your needs. All working on dierent
room environments. Depending on the plant built, the secons
ENVIRONMENTS and HEAT PUMP may not be present.
1.1 HOWDOESITWORK
The system can consist of:
• HCC touch panel, which will allow you to monitor and set
all operang parameters;
• KITA heat pump, which will work to generate the ideal
temperature;
• FLOOR I / O boards, which handle mixers;
• ROOM sensors for environments that works for monitoring
the parameters of the individual rooms.
The system is able to handle up to 3 dierent I / O FLOOR boards
separately and up to 12 controllable environments. In case it is not
necessary to work on many environments, the sensors can also be
installed independently, without an I / O FLOOR board.
1.2 Proles
To meet the savings requirements and then opmize the
energy expenditure of climate devices, you can set the system
and environments to work in 3 dierent proles: ECO, DAY and
NIGHT. Each of them is divided into 2 dierent values depending
on whether the located system is working in heang mode or
cooling mode. These proles can work at dierent temperatures
and for each one of them you can set the setpoint, or the
temperature to be reached. In this way it is possible to select the
preset setpoint for each prole and with a simple touch switch
from one to another (see 3.2 and 4.1).
Once you select one, all acve environments will work using
the same prole. However, each setpoint can be set individually
for each environment. This means that even if, for example,
all environments will work with ECO prole, however, the ECO
Setpoint of an environment may be dierent from the ECO
Setpoint for another environment, as well as the ECO setpoint
in cooling will be dierent from ECO Setpoint of the same
environment but in heang mode.
We recommend using ECO prole for Setpoint to make the heat
pump do a lile work, to be used when there is no one in house
for long periods of me, such as during the holidays, but you do
not want to switch o the system. When no prole is selected,
on rst start the default is ECO prole. On defaout this setpoint
is set at 20°C for heang and 25°C for cooling.
We recommend using DAY prole for everyday Setpoint, when
you want to make the house comfortable for the people living
there. On defaout this setpoint is set at 22°C for heang and
23,5°C for cooling.
We recommend using NIGHT prole for night use Setpoint, when
the need to work on the climate is less. On defaout this setpoint
is set at 18°C for heang and 26°C for cooling.
There is a fourth prole, MANUAL, which is acvated when the
scheduling is deacvated (see chapter 5). The rst 3 proles are
used only while the scheduling is acve, but when you switch to
manual this prole comes in place, which can be used for special
or temporary Setpoint, both for the plant and for the sensors.
When manual prole is acve, also the mode automacally
switchestomanual(see1.3Mode)andallmanualsetpointfor
individualenvironmentsbecomesacve.
If scheduling is working and no prole is acve, the heat pump is
not switched o, but it will work using default setpoint in order
to consume less energy as possible. In this specic case, the
setpoint of the ambients will no longer be visible.

1.3 Mode
The heat pump can work in three dierent modes, WINTER,
SUMMER and DHW (see 3.1 and 3.3).
WINTER is used when you want to generate heat, SUMMER is
used when you want to generate cold air, DHW is acvated in
combinaon with the previous if you want to produce at the
same me hot water for domesc use. Each of these modes is
associated with a dierent setpoint and the heat pump will use
them to work properly.
These 3 modes are combined to ECO, DAY and NIGHT proles,
so the Setpoint WINTER - ECO is dierent from the Setpoint
WINTER - DAY.
Once set these three setpoint, with a touch you can acvate the
desired one for the plant. Aer that, the pump will begin to work
to get the water to the set temperature to then distribute it in
environments that request it.
The default values are WINTER 35°C, SUMMER 12°C, SANITARY
47°C, for all 3 proles.
For the mode too, such as proles, there is a manual setpoint.
1.4 ChangingsetpointsviaROOMSensors
By default, changing the setpoint is enabled only through the
HCC touch panel, but you can also enable changing from the
installed sensors.
To enable the setpoint modicaon directly from the sensors,
you have to go to the Other screen (see 4.3.3) and turn on the
appropriate ag.
To enter in “Setpoint Change” mode from the sensor, you must
press the 2 buons on the sensor simultaneously for at least 2
seconds. The current setpoint will then be displayed. It is now
possible to modify it by increasing it using the right buon and
decreasing it with the le buon, with 0.5 ° steps.
If the sensor buons are not pressed for more than 2 seconds, it
automacally exits the “Setpoint Change” mode and switches to
the standard screen.
This screen is displayed for 60 seconds, aer which the screen
will go into stand-by and will be reacvated at the rst touch.

Maximum permied outlet temperature .
Passing this temperature will trigger an alarm.
It is possible to modify it, but it is recommended
to maintain 35°C.
Minimum permied outlet temperature . The
system will work to prevent the outlet water
temperature from being lower than the one
shown here. In cooling mode it may be the
highest dew temperature registered by the
ROOM sensors connected to the I/O FLOOR
board, which prevents the formaon of dew
in the cooled environments, or it may be an
arbitrary value (see 4.3.3 Builder).
Delta. Indicates the dierence between inlet and
outlet temperature inside radiang system. By
seng a value, the system will try to work more
or less quickly to maintain that dierence. Higher
values will slow down the circulator, lower values
will speed it up.
Acve relay. These icons indicate (green) the
relays currently acve on the FLOOR I/O board.
3 HEATPUMP
The HEAT PUMP secon is dedicated to the most important heat

the two colors match the heat pump has
passed to the new state. If the external color
is not visible then there are communicaon
problems with the heat pump.
Buer. It shows the water temperature that
the buer stores to heat or cool the house.
Color indicates whether you are producing
hot (red) or cold (blue) water.
In case the plant has no buers then the
icon will be replaced by a radiang system
.
Domesc hot water buer. It shows the water
temperature that the buer stores to heat the
domesc hot water. Clearly, in order to produce
sanitary hot water it is necessary to select the
DHWmode(see 3.2 Pump sengs) and that there
is a dedicated puer.
The arrows indicate where the produced water is
directed.
When the pump is producing technical water, the arrows
appear on the le side, when it produces domesc hot
water the arrows appear on the right side.
Wintermode. When turned on, indicates that the heat
pump is producing hot water.

DHW setpoints. With this pop up you can also turn
the manual prole on or o (vedi 1.2).
Acve setpoint. In the middle of the screen
you can see the current acve setpoint used by
the heat pump. If Climac Curve or Opmizer
are acve, the displayed value may dier from
those shown below the mode icons. Touching
the displayed value will show the Climac Curve
screen. At the boom of the acve setpoint are
Climac Curve and Opmizer icons. If one of the
icons is black and not gray then that feature is
acve.
If the air controlled compressor funcon is acve (see 4.3.3), the
screen will appear dierently and only the prole setpoint can
be changed.
3.2.1 Climaccurve
In this screen you can acvate the climac curve and set its
operang values.
The climac curve is a funcon to vary the setpoint in use based
on the outside temperature, so that the heat pump works only
when it is really needed.
WARNING!
If the heat pump is already using its’ own climac curve, be sure
to turn it o before turning this climac curve on.

The climac curve calculates a Delta that will be combined with the
setpoint currently in use.
A1. The lower average external temperature of the graph. At this
outdoor temperature, or lower, the starng point for the Delta
calculaon will be the temperature indicated by A2.
B1. Indicates average outdoor temperature of 0 °. With an external
temperature of 0 ° the desired temperature for calculang the Delta
will be B2.
C1. The highest average external temperature of the graph. At this
outdoor temperature, or higher, the Delta calculaon set point will
be C2.
The graph of the climac curve shows on the vercal axis the
temperature to be generated and on horizontal axis the average
external temperature.
The graph draws a curve (red line) that intersects (i point) with the
current average external temperature (white line). The lemost
point of the curve (A2) represents the desired maximum delivered
temperature, while the rightmost point (C2) is the minimum desired
temperature. The delivered temperature dierence (A2 - i) is the nal
Delta that will be combined with the current setpoint.
This means that if my current setpoint is the same as shown on A2then
the graph will correspond to the current operaon, but if I change my
current setpoint the resulng eect is similar to translang the curve.
On/O. By tapping the icon you can acvate or deacvate the
climate curve. Once acvated, the nal setpoint will change
depending on the curve and outside temperature, and will
replace the setpoint in use based on the generated delta.
External temperature. Reports the average
outdoor temperature calculated over 24 hours.
This value is used as a parameter for calculang
the climac curve.
Base setpoint. Shows the setpoint value
of the mode currently in use, without any
climac curve changes.
Delta. Once the climac curve is acvated, here is
how much the base setpoint will change.
Final setpoint. Once the climac curve is
acvated, the delta will be applied to the
base setpoint. The result is the new setpoint
that will be used by the heat pump.
Opmizer. If the icon is light gray then it is turned o, if
it is black then it is running. By tapping the icon you will
open the opmizer screen where you can acvate it.
Close screen. By tapping this icon you can return to the
heat pump sengs screen.
3.2.2 Opmizer
In this screen you can acvate the opmizer and set its operang values.
The opmizer is a funcon that allows the heat pump setpoint
to be varied based on the outside temperature, raising it when
the outside temperature is higher, so it is more favorable to
heat exchange, or lowering it when outside is colder, when the
exchange heat is unfavorable.
On/O. By tapping the icon, you can enable or disable
the opmizer. When acve, the nal setpoint will change
depending on the outside temperature and will change
the setpoints set in the modes, without exceeding the
limits set by Max and Min.

Maximum outlet temperature: If mixing
management is not acve, this value
indicates the maximum outlet temperature
delivered by the heat pump. In this case the
temperature also becomes the maximum
outlet temperature allowed for the I/O
FLOOR boards (see 2.4).
Fancoil and mixing acvaon: The 2 icons
are used to acvate the use of fan coils (top
buon) and mixing (boom buon). For a
fancoil or a FLOOR mixing board to be usable
it must be installed and enabled. As an
alternave it is possible to use fan coils and
mixers not supplied by Templari. In this case
the alternave cards cannot be completely
controlledbytheHCCsystem.
4.1.1 Changelanguage
In this screen you can set language used by tapping the ag of
the chosen language.
4.2 Advanced
In this screen you can set more specic funcons. The screen is
password-protected and only competent personnel can access it.
The plant can work with up to 12 ROOM sensors and 3 I/O FLOOR
board. Each sensor can be associated with a fancoil. All is summed
up by the screen graphics.
The sensors and mixers are in constant communicaon with the
HCC panel to be able to work best, but if for some reason more than
10 consecuve read and / or write errors occur on a device, that
device will be disconnected to avoid HCC working with a potenally
damaged or defecve component (see 4.4 Alarm).
Screen saver. BL indicates how many minutes
of inacvity the panel will turn o the monitor.
SS indicates aer how many minutes of
inacvity the screensaver will start.
Panel name. It is possible to set a name for the HCC
panel with a maximum of 20 characters. This name
will idenfy it during remote monitoring.
Serial number. Here you can see the serial

number of the panel, inserted during the rst
start-up. The serial number will idenfy the panel
in some of the remote services.
Floor mixer. If a I/O FLOOR board has been
installed, it have to be enabled by touching the
icon. Otherwise the card will be inacve. If non-
Templar mixers are used, this procedure is not
necessary.
Sensor and fancoil. If a sensor is installed, here you can
indicate whether to work with it or not, by tapping the
icon. Next is the fancoil icon. If a fancoil is installed in the
same room where the sensor is installed here it is possible
to indicate whether the sensor will work in accordance with
it or not, by tapping the icon. If the fancoil icon is light gray
then there is no fancoil installed for that environment, if
it is dark gray then it has been installed and is present, if
it is light on then it is selected as acve and will work in
accordance with the sensor.
It is also possible to associate more fancoil with a single
sensor. If more fancoils are present and acve in the same
sensor quartet, but one of the acve fancoils does not
have a sensor icon on his side, then that fancoil will work
in accordance with sensor number 1. This way, you can
associate to sensor 1 up to 4 fancoil at the same me.
Reboot. By tapping this buon the HCC touch
panel will restart.
Reset. Toccando questo pulsante e
confermando il reset nella seguente nestra di
conferma, il pannello HCC verrà riavviato e tu
i valori verranno resea a quelli di fabbrica.

This screen is password protected and only qualied personnel
should access it.
From here you can access all the sengs required for the installaon
of the system.
WARNING!
Every me a peripheral is installed, the installaon must be noed
to the system by switching on the buon on this screen. If not, the
system will not work properly and could lead to damage to the system.
MODBUS mixer address. Here you can see and
change the address used in the MODBUS network to
communicate with the installed FLOOR I/O mixer board.
Once the mixer is installed, to nofy to the panel, touch
the buon to lit it on. A lit o buon indicates that a
mixer with that address has not been installed.
If the mixer is not provided by Templars, this procedure
may not be necessary.
NOTE: As the default value, mixer addresses are 128,
133, and 138.
MODBUSsensoraddress. Here you can see and change
the address used in the MODBUS network to communicate
with the ROOM sensor installed.
The le-most dot indicates that a sensor has been
installed, the right-most dot indicates that it is valid for

Once the sensor is installed, to nofy the panel, it is
necessary to touch the line of that sensor to open the
screen dedicated to it and press the buon indicang that
it has been installed (see4.3.1ROOMsensorsengs).
NOTE: The default values for the sensor addresses are
129, 130, 131, 132, 134, 135, 136, 137, 139, 140, 141, 142
MODBUS fancoil address. Here you can see and
change the address used in the MODBUS network to
communicate with the installed fancoil.
The le-most dot
indicates that a fancoil has been installed, the right-most dot
indicates that it is not a fancoil supplied by Templari. Fancoil
not supplied by Templari are then interfaced to the system
with a Templari expansion card and not all the funcons can
be available.
