1 GENERAL NOTES
1.1 PERMITTED USE
The touch screen remote control panel allows the centralized management of a network of chiller/heat pump. It can also be used
for partial functions (i.e. as a remote control panel of a single chiller/heat pump or ambient temperature thermostat).
It includes humidity and temperature sensors for the thermo hygrometric analysis of the environment and for the management of
the double set point for radiant floor heating systems that use a dehumidification system.
The intuitive interface simplifies the use of the control; all the functions can be easily set through the use of immediate
understanding synoptic.
The remote control supervises and periodically examises the network, there is a cycle time that elapses between the signaling or
command request and the activation of the function, the cycle time depends on the largeness of a network of fancoils and heat
pumps.
For multi-circuit units only the I/O ports and parameters of the first circuit can be displayed.
1.2 USE NOT PERMITTED
Any use different than that permitted is PROHIBITED.

2.1.2 TOUCH-SCREEN USE
The interface has a resistive touch-screen LCD with sensitive areas applied to the contextual content of the active screen.
It allows you to select items or perform functions with ease.
Do not exert too much pressure on the touch screen with your fingers and do not use a sharp object on the touch screen. Doing so
may damage the touch screen or cause it to malfunction.
It is advisable to exert weaker pressure and not too fast on the screen and to become familiar with the use of the touch-screen
itself, well calibrating the touch of your fingertip on the sensitive areas of the screens.
Do not put the touch-screen in contact with other electrical devices. Electrostatic discharge may cause a malfunction.

2.4 INSTALLATION
The Touch Screen control is used for fixing to the wall according to DIN 503 standard.
In the rear part of the control some pre-drilled holes are present to be detached pursuing a pressure with a screwdriver, in such a
way as to obtain the holes useful to the fixing. Of the 6 holes, use only the outer 2 holes of the horizontal series (see Figure 3).
Before you do this, open the control itself, applying a slight pressure in the lower and upper parts of the control, in order to
separate the rear cover from the front one.
Use the rear panel and apply the holes in the two slots shown in the figure below.
Do not directly use the panel as a template to drill the holes on the wall; the electronics may be damaged during this operation.
Figure 3. Holes for wall mounting.

3USER INTERFACE
The touch-screen can be used in the following ways:
•Interface panel (unit interface) for a single heat pump
•Chillers/heat pumps network network manager
•Manager of Chiller/heat pump and fan coil units network
•Fancoil units network manager
To manage the system modularity, the interface foresees a home page which summarizes the whole plant, showing dynamically the
enabled resources and hiding the ones not available in the current configuration. The interface also provides a second summary
page including all the values of temperature and humidity detected in the system.
Through the menu it is possible to access to:
•Plant configuration
•Single units statuses
•Settings of machines, zones and plant system.
As alternative it is possible to directly access from the home page to detailed information, pressing on the display where are located
the summarized information. E.g., pressing where are located the main information of the heat pump, you can enter in the menu of
the heat pump status.
3.1 ICONS DISPLAY
All icons on the different screens can be shown in full colours or de-saturated as in the following example:
The colour saturation indicates that icon is usable; when pressed the related function is performed.
The transparency (de-saturated) indicates that icon is not usable and any touch on it has no resulting action.
For what concerns the side sliding bar which appears on the left side of the screen related to the single units connected into a
network (see Paragraphs 3.4.1.3), if an icon appears fully coloured the related function is enabled and, in that specific moment is
also active (i.e. if the “water anti-freeze” icon of the heat pump is present and coloured, as shown below, the plate exchanger
electrical heating elements are switched on).
Instead, if the icon appears but is transparent (de-saturated), the related function is enabled but not that moment activated (i.e. if
the “water anti-freeze” icon of the heat pump appears transparent, as shown below, the plate exchanger electrical heating
elements are ready to work but currently switched off).
3.2 SCREENS AND ICONS
There might be some differences between screens and icons as they are currently shown. The Company reserves itself to modify
and update them without prior notice and in relation to what shown in the present manual.

Figure 5. Home page – indication meanings
From the home page it is possible to access to the different device’s screens, simply touching the displayed resource.
The sensible areas (indicated in the image by red boxes) inside this page are:
1. Heat pump/chiller (for multi-circuit units only the I/O ports and the parameters of the first circuit can be displayed.)
2. Status system and mode system display
3. Fan coil (with a status message of dehumidification active mode)
4. Display of any active alarms in the system
5. Name of the keyboard (access to information on the firmware version)
6. Configuring the Ethernet network
7. Log-out (intermittent symbol if it’s active)
8. Arrow of navigation, next page.
Graphically, it also contains information on the presence or absence of the following utilities:
9. Storage tanks (plant or if solar storage tank is present)
10. Radiant panels
11. Sanitary
12. Solar.
On the main screen, in fact, it appears only utilities present and properly installed in the network or the active warnings at the time
of viewing.
If, for example, the network consists only of one or more chillers/heat pumps, without production of sanitary water and without
storage tank, the screen shows graphically the presence of the chiller, but inside the house do not appear other objects; in this case
the appearance is as below:
