Perform the installation in such a way that the probe is accessible for any maintenance work.
5. Display The touchscreen display allows you to control the system using the following buttons and icons: “Away” button Button “Settings Menu” "Increase" button "Back" button "Decrease" button "Confirm" or "Nighttime reduction" button Fig. 3: Graphical interface and buttons 5.1 Functions of the buttons : increases the numerical values and, in the process of navigation, scrolls through the available menus.
• 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. 5.2 Symbols Depending on the different operating modes, the following icons could also be displayed: : Calibration : Entering the PIN : Away...
Fig. 5: Locking with PIN 6. 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 •...
6.1 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. When the thermostat is OFF, you cannot perform any operations other than activating the menus. Fig.
Fig. 8: Manual set point setting The selection is confirmed by touching icons in the lower right corner indicate whether the system is operating in heating or air-conditioning mode respectively (icon illuminated = system on). 6.3 Away This mode is useful to achieve energy savings quickly and effectively whenever the user leaves the reg- ulated room.
Activation of this mode is identified by the icon above the temperature indicator: Fig. 10: Away Mode To exit and return to Manual mode touch the button again. 6.4 Nighttime reduction This is the typical mode to use at night to reduce system consumption significantly. In "Nighttime reduction"...
Activation of this mode is identified by the icon above the temperature indicator: Fig. 12: Nighttime reduction mode To exit and return to Manual mode touch again. 6.5 Antifreeze This mode, which can only be activated when the system is operating in heating mode (see par. 7.3), 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.
6.6 Remote reduction Remote reduction is a useful way to "centralize" energy saving if there are multiple 02950 thermostats in different rooms of the same house. It is similar to Nighttime reduction mode with the only difference being that activation is by remote control.
6.7 Remote activation This mode is typically used in applications where you want to remotely enable or disable temperature control of a room and limit the functions that can be performed by the user. For example, this is a typical mode in hotel room management. This mode comes into operation when the multi-function input is activated (see par.
7. Settings menu From the settings menu you can configure all the features of the thermostat. On the main screen (see Fig. 3) tap the icon. From the main menu, using will display the following (flashing) symbols in succession, which provide access to the corresponding submenus: operating mode setting unit of measurement setting heating/air-conditioning setting...
7.3 Heating/air-conditioning setting This menu lets you set the operation of the device depending on the season (winter/summer): • heating • air-conditioning Using select the desired operation and confirm with 7.4 Temperature set point setting This menu lets you set the temperatures and hystereses necessary for defining the temperature control set-point used in the different operating modes.
7.4.2 Away temperature The menu, via lets you increase/decrease the value of the away temper- ature The away temperature, preset by the installer, is an intermediate temperature between that of Manual and Antifreeze mode, geared to obtain substantial energy savings during periods when the user is away.
7.4.7 External probe alarm temperature The menu, via , lets you set the temperature limit (read by the external probe) at which the thermostat switches off the heating system and triggers an alarm (useful to protect underfloor systems against overheating). To view this menu, the external temperature probe must be set as a "limitation"...
• remote activation: the multi-function input (when enabled) automatically sets the “Tcomfort” tem- perature as the setpoint. In this context, the user can only change the temperature within a narrow range (see: 8.4.5) and cannot carry out any further operations on the device; with the multi-function input disabled, the default mode is "Antifreeze"...
the load on the system; in general, the rule is that Tb can be that much higher (and therefore put fewer demands on the system), the slower the system or the larger the environment to regulate. to confirm your choice. 7.9 Colour setting This menu is used to select the background colour of the display.
7.10 Standby brightness level setting The menu lets you set the brightness level when the thermostat is in standby mode. select one of the following levels with gradually increasing brightness: • • • • • • • While scrolling through the values, when the selection stops on a certain level, the brightness of the display will, for approximately 2 s, take on the brightness corresponding to the selected level in order to allow the user to check the visual effect.
10. Cleaning the device The device features a touchscreen display with capacitive buttons and therefore requires you to be gentle during the cleaning phase. Avoid using aggressive products. Clean the display with a special cloth for cleaning lenses. 11. Main characteristics •...
