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 pre-

vious digit.

N.B.: The field/value being edited is highlighted by the field/value itself flashing.

“Away” button

"Increase" button

"Decrease" button"Back" button

"Confirm" or "Nighttime reduction" button

• If no operations are performed on the device for 30 seconds, the brightness of the backlighting decreas-

es, 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).

3.1 Switched off (OFF)

In this mode, the thermostat is turned off and you cannot make any adjustments; in this case, the

icon is displayed above the temperature indicator.

Fig. 4 : Typical screen for OFF mode

For heating-only systems this mode is typically used in the summer.

3.2 Manual (ON)

This is the "traditional" operating mode. The thermostat controls the room temperature and takes it to

the value set by the user.

Figure 5: Typical screen for Manual mode

The set point can always be changed via or .

In the process of setting, the set point flashes; the colour1of the display may also vary, providing an indi-

cation of the expected consumption associated with the setting being made:

green yellow red

optimum consumption excessive consumption

1Only if the colour set for the display is white (C0) or ECO, see par. 8.9.

Fig. 6: Manual set point setting

The selection is confirmed by touching .

The and icons in the lower right corner indicate whether the system is operating in heating or

air-conditioning mode respectively (icon illuminated = system on).

3.3 Away

This mode is useful to achieve energy savings quickly and effectively whenever the user leaves the reg-

ulated room.

In "Away" mode the system makes the adjustment according to the "away temperature" setpoint

(see para. 4.4.2) which is more cost-effective than the manual setpoint and different to switching off the

system completely.

The Away mode can only be activated in manual mode by touching .

The display will show the "away temperature" setpoint for approximately 2 seconds:

Fig. 7: Input in away mode showing the away temperature

Activation of this mode is identified by the icon above the temperature indicator:

Fig. 8: Away Mode

To exit and return to Manual mode touch the button again.

3.4 Nighttime reduction

This is the typical mode to use at night to reduce system consumption significantly.

In "Nighttime reduction" mode the device reduces the consumption of the system, taking the room tem-

perature to a lower value (or higher, if on air-conditioning) than the Manual mode by degrees (see

par. 4.4.4).

"Nighttime reduction" is activated starting from Manual mode by touching or remotely via the

multi-function input (if enabled).

The display will show the "nighttime reduction" setpoint for approximately 2 seconds:

Fig. 9: Input in Nighttime reduction mode showing the reduction set point

Activation of this mode is identified by the icon above the temperature indicator:

Fig. 10: Nighttime reduction mode

To exit and return to Manual mode touch again.

3.5 Antifreeze

This mode, which can only be activated when the system is operating in heating mode (see par. 4.3), lets

you set a minimum temperature value ( setpoint) to avoid damage to the pipework or to keep it from

falling below a certain safety level when you are away for lengthy periods in the winter.

The "antifreeze" mode is activated directly from the Settings menu (see par. 4.1).

Once activated, antifreeze mode is identified by the icon above the temperature indicator.
