VIMAR 02950 Touchscreen Thermostat

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 touchscreen 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.

Display
The touchscreen display allows you to control the system using the following buttons and icons:

Functions of the buttons

increase 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 anymore 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 anymore 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 the restoration of the normal functions

Symbols
Depending on the different operating modes, the following icons could also be displayed:

Ecometer

On the left-hand side of the display, there is a set of icons called the “ECOMETER” that provides an overview of the expected consumption. The color of the display, if configured in “ECO” mode, shows the expected consumption provided by the ECOMETER via the background color (see 4.9). This indicator facilitates system management geared to energy saving by associating a different color depending on the estimated forecast.

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 from being used by unauthorized persons: the device prompts you to enter the PIN, indicating a shutdown.

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 temperature 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).

Switched off (OFF)
In this mode, the thermostat is turned off and you cannot make any adjustments; in this case, the icon off is displayed above the temperature indicator.

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

Manual (ON)
This is the “traditional” operating mode. The thermostat controls the room temperature and takes it to the value set by the user.

The set point can always be changed via or . In the process of setting, the set point flashes; the colour1 of the display may also vary, providing an indication of the expected consumption associated with the setting being made:

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

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).

Away
This mode is useful to achieve energy savings quickly and effectively whenever the user leaves the regulated 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:

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

To exit and return to Manual mode touch the button again

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 temperature 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:

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

To exit and return to Manual mode touch again.

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

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. Example: Before going to bed, using a simple switch, all the thermostats in the house are set onto “reduction” at the same time. This mode comes into operation when the multi-function input is activated only if this has been suitably configured by your installer. The multifunction input is activated solely when the thermostat is in Manual mode. In “remote reduction” mode, the device sets the temperature to a value below Tcomfort. In this condition the display and its buttons have limited functions; access to the settings menu is disabled and you can only change the temperature setpoint within a limited range. The “Remote reduction” mode is identified by the and icons located simultaneously above the temperature indicator. The and buttons in any case let the user change the temperature in a limited range.

On disabling the multi-function input, the thermostat returns to the previously set mode and the user can again manage the device completely.

 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 (typical mode for hotel room
management). This mode comes into operation when the multi-function input is activated only if this has been suitably configured by the installer. In “remote activation” mode, the device sets the temperature to a value equal to Tcomfort. In this condition the display and its buttons have limited functions; accIn “remote activation” mode, the device sets the temperature to a value equal to Tcomfort. In this condition the display and its buttons have limited functions; access to the settings menu is disabled and you can only change the temperature setpoint within a limited range. The “Remote activation” mode is identified by the icon located above the temperature indicator. The and buttons in any case let the user change the temperature in a limited range. ess to the settings menu is disabled and you can only change the temperature setpoint within a limited range. The “Remote activation” mode is identified by the icon located above the temperature indicator. the and buttons in any case let the user change the temperature in a limited range.

On disabling the multi-function input, the thermostat switches to Antifreeze mode (system on heating) OFF (system on air-conditioning) and the user can again manage the device completely.

Settings menu
From the settings menu you can configure all the features of the thermostat. On the main screen (see Fig. 1) tap the icon. From the main menu, using and will display the following (flashing) symbols in succession, which provide access to the corresponding submenus:

Touching opens the submenu and then the flashing highlights the parameters of the submenu.

Colour setting
This menu is used to select the backgroupd colour of the display. In addition to the four default colours, you can set a colour to your choice selected from the full range o colours, or set “ECO” mode in which the display colour is a clue to the expected level of consumption in the building.

Via and you can select:

ECO mode therefore does not display the colour as a function of the temperature measured at that time but only in relation to the setpoint. Lastly, tap to confirm your choice.

Standby brightness level setting
The menu lets you set the brightness level when the thermostat is in standby mode Via and 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. Lastly, tap to confirm your choice.

Info
This menu is for the sole use of the installer.

Lock/unlock PIN setting
This menu lets you add/change the password to inhibit use of the thermostat. Using and set the three digits of the PIN one at a time and then confirm each set digit with . If you wish to have free access to the thermostat (so without it prompting you for a password) it is sufficient to set the PIN to “000”.
IMPORTANT: Take care to note down the password so that you can use it again for the device when needed

Alarms
The thermostat is capable of displaying an alarm condition associated with the use of the external temperature probe; in this situation, the device controls the system independently so the alarm will cease in a matter of minutes.

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.
