1. Thermostat 02950
The thermostat 02950 is designed to control room temperature by acting on the control circuit of the burner
or circulation pump (heating) or on the control circuit of the air conditioner (air conditioning), ensuring an ideal
temperature. Thanks to a touch screen display with an extremely user-friendly graphical interface, the user can
manage the system easily and comprehensively while keeping the environment in a state of energy saving.
2. Display
The touchscreen display allows you to control the system using the following buttons and icons:
Figure 1: graphical interface and buttons
2.1 Functions of the buttons
: increases the numerical values and, in the process of navigation, scrolls through the available
menus. When it "disappears" from the display it means that the value cannot be increased any
more or the first of the scrollable items has been reached.
: decreases the numerical values and, in the process of navigation, scrolls through the available
menus. When it "disappears" from the display it means that the value cannot be decreased any
more or the last of the scrollable items has been reached.
: confirms the selected option (activates the submenu if there is one or displays the next
parameter/digit).
After each confirmation, the display shows the icon for approximately 1 s.
: back (or cancel) exits the current screen/menu and returns to the previous one without saving
any changes. In menus with changes to multiple digits it lets you go back to change the previous digit.
N.B.: The field/value being edited is highlighted by the field/value itself flashing.

• If no operations are performed on the device for 30 seconds, the brightness of the backlighting decreases, and the touch screen does not respond to touch (thus you avoid the effects due to inadvertent
touching and the backlighting is less “invasive”); on standby the button symbols are no longer visible
because they are disabled.
• To exit standby mode, touch the screen and see that the button icons appear. The increase in the
brightness level of the device and the appearance of active buttons will confirm restoration of the normal
functions.
2.2 Symbols
Depending on the different operating modes, the following icons could also be displayed:
: Calibration
: Entering the PIN
: Away
: Manual (ON)
: Nighttime Reduction
: Antifreeze
: OFF
: Multi-function input ON
: External temperature probe
: Alarm
: Air conditioning
: Heating
: Confirm
2.3 Ecometer
Figure 2: set of ECOMETER icons
On the left-hand side of the display there is a set of icons called the "ECOMETER" that provide an overview
of the expected consumption.
The colour of the display, if configured in "ECO" mode, shows the expected consumption provided by the
ECOMETER via the background colour (see 4.9).
This indicator facilitates system management geared to energy saving by associating a different colour
depending on the estimated forecast.

2.4 Locking the interface via PIN
The thermostat lets you set a password (see par. 4.12) which inhibits any change to the operating mode
(eg switching from Manual to OFF), limits setting the temperature values and, more generally, blocks
access to the configuration menu.
This feature is useful to prevent the thermostat being used by unauthorized persons: the device prompts
you to enter the PIN, indicating a shutdown with the icon.

3. Operating mode
The thermostat 02950 is able to adjust the temperature according to the following operating modes:
• Switched off (OFF): switches the system off
• Manual (ON): lets you set the environment temperature set-point manually
• Away: lets you set the set-point in order to achieve significant energy savings during periods when the user
is away
• Nighttime reduction: this mode, which can be activated locally, is useful for changing the manual adjustment
set point in the hours of nighttime operation.
• Antifreeze: used to set a minimum temperature level to avoid damage to pipework or prevent the temper-
ature from falling below a safety level.
In addition, if the multi-function input of the thermostat has been suitably configured (your installer will give you
the relevant information), you can remotely activate the following modes:
• Remote reduction: conceptually similar to nighttime reduction, it acts on the comfort set point instead of
the manual set point
• Remote activation: lets you activate the system remotely by setting the comfort set point
The operating mode is selected via the SETTINGS menu (see chap. 4).
