2 Description
2.1 General features
The thermostat with display can be used both in heating and in air conditioning systems, and gives
the possibility of adjusting the temperature on 5 levels. Comfort, Eco, Antifreeze / Thermal Protection, Automatic, and Manual.
Based on the type of use, the backlit display will show the following information: the current function or mode (heating, cooling, or automatic function; Comfort, Eco, Antifreeze / Thermal Protection, Automatic, Temporary Manual, or Off ), the detected room temperature, the temperature set
point defined, the fan-coil speed, and the status of the zone.
The thermostat can be used in MyHOME temperature control systems (MyHOME probe with central unit), hotel room systems, or residential systems (individual system). The configuration can be
done by connecting the configurators to the corresponding sockets in the back of the thermostat,
or using the MyHOME_Suite software.
Programming is simple and intuitive: to switch from one mode to the other press MODE, + or – .

3 Possible applications
Installer manual
3.1 Installation
Installation in a MyHOME temperature control system
Thanks to the internal sensor, the thermostat can operate as master probe of a MyHOME system. In
this case it will obtain the settings from the central unit managing the system.
Using the + and – keys, it is possible to enter settings different from those of the central unit; the
new settings are temporary, and will only be applied until the next central unit set-point change.

Installer manual
Installation in hotel room
The operation in the hotel room configuration gives the customer the possibility of easily setting
the temperature to the desired level of comfort. The hotel manager can integrate the individual
thermostat installed in the room as part of a system that can be managed using a software for the
monitoring of consumptions, therefore avoiding unwanted energy waste.
Installation in individual residential system
The third type of use, as room thermostat, manages the temperature control of an individual
system, without the need for additional control devices.

4 Configuration
Installer manual
4.1 Physical or advanced configuration
Depending on personal requirements and the type of system to install, the thermostat may be
configured in two ways: physical or advanced configuration.
The physical configuration is completed by connecting the configurators to the appropriate sockets on the back of the thermostat.
If no physical configurators are connected, the device can be configured virtually by connecting it
to a PC and using the dedicated MyHOME_Suite software.
In this way it is possible to simplify the configuration operations in large systems, without the need
to manually intervene on each device.
The advanced configuration also gives the possibility to control several actuators with one single
thermostat, and to configure the automatic changeover mode (heating / cooling).
For the configuration see the product technical sheet.
11
Thermostat with display
5 Functions and operating modes
Installer manual
5.1 Heating and cooling function
The thermostat can be set for the management of four different functions, depending on the type
of system to install:
- heating function (only the heating is active);
- cooling function (only the cooling is active);
- cooling function in summer / heating function in winter;
- automatic changeover between cooling and heating (not available in MyHOME systems).
The setting of the function (with the exclusion
of the use as MyHOME probe) can be modified with an extended pressure of the MODE
( > 7 seconds). For the Hotel mode of operation only it is possible to change the function
using the Mode key (performing the configuration using the MyHOME_Suite software).
Heating function
If the measured temperature is lower than the reference value, the heating system is activated and
the corresponding symbol appears on the display .
When the temperature is reached, the thermostat switches the zone off and the icon disappears.
Note: The heating icon is always displayed
.
Cooling function
If the measured temperature is higher than the reference value, the cooling system is activated
and the corresponding symbol appears on the display
.
When the temperature is reached, the thermostat switches the zone off and the icon disappears.
Note: the cooling icon is always displayed
.
Summer / winter function
By configuring the thermostat both for the winter (HEAT) and the summer (COOL) functions, it is
possible to use it with the heating system in winter, and the cooling system in summer.
The icons shown on the display will be the same as the ones previously described for the heating
and cooling functions.
12
Thermostat with display
5 Functions and operating modes
Installer manual
5.2 Automatic changeover function
(available starting from version 1.3 of MyHOME_Suite)
(Not available in MyHOME systems).
The thermostat can be programmed for automatic changeover between the heating and the cooling
functions. When programmed in this way, the ( /
) icons are not displayed.
Depending on the temperature measured, the heating or cooling system in operation symbols
( / ) will appear, to indicate that the corresponding function is active.
Note: Automatic changeover mode cannot be configured physically, but must be enabled during
the advanced configuration (using the MyHOME_Suite software).
This function can be used when it is necessary for the thermostat to automatically manage the
changeover between heating and cooling, and is for example useful in case of 4 tube fan-coils.
Using the MyHOME_Suite software, it is possible to set the range of temperature at different levels,
for the activation of the heating and the cooling systems, depending of the thermal inertia of one’s
own system, and specific requirements.

The switching from the heating to the cooling function, and vice versa, depends on the rules listed
in the following table (T° represents the measured temperature).

5.2.2 Automatic function in Comfort, Eco, and Protection mode
Automatic changeover depends on the operating mode selected: comfort, eco, or protection.
In this case, the heating and cooling ranges must have been previously set in the corresponding
modes (see paragraph 6.3).
Therefore, two parameters for each mode must be set: a high set-point to set in the cooling function, and a low set-point to set in heating mode.

7.3 In case of error
When the display shows the “Er” symbol followed by a number, the thermostat is indicating an

Below is a list of possible errors:
Er1
No response from pump.
Er2
No response from actuator.
Er3
No response from slave probe.
Er4
Temperature sensor fault.
Er5
Internal error device.
With errors “Er1”, “Er2”, and “Er3” the thermostat keeps the current mode and the displayed error
condition can be reset (by pressing any key). If the error condition persists, after 15 minutes the
error screen will reappear.
With errors “Er4”, and “Er5” the thermostat switches OFF, and all the actions that can normally be
performed by the user, like the pressure of the keys, are disabled.
Below is an example of an error screen (*).
(*) NOTE:if ER4 or a temperature very different from the one felt are displayed, or after the first
installation, wait at least 5 hours before checking the operation again, or carrying out
