5. Display The touchscreen display allows you to control the system using the following buttons and icons: “Away” button Button “Settings Menu” "Increase" button Central area "Back" button or view powers "Decrease" button "Confirm" or "setting extension" button Fig. 7: Graphical interface and buttons 5.1 Functions of the buttons : increases the numerical values.
• 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 inad- vertent touching and the backlighting is less "invasive"); on standby the button symbols are no longer visible because they are disabled.
5.3 Locking the interface via PIN The timer-thermostat lets you set a password 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.
Each sector can be composed of 1, 2 or 3 dashes: = “T away” ( = “T economy” ( = “T comfort” ( The clock shows the current time. The indicator of the day of the week highlights the current day with a dash under the number associated with it (eg, 4 = Thursday).
CAUTION: Proper operation and proper consultation require: • The energy probe 02960 to be powered and functioning • The energy probe 02960 and timer-thermostat 02955 to be connected correctly • The clock of the timer-thermostat to be set correctly If these conditions are met, the indicator LED of the energy probe will flash "occasionally"...

(hours/days/months/years). 6. Operating mode The timer-thermostat 02955 is able to regulate the temperature according to the following operating modes: • Switched off (OFF): switches the system off • Manual: lets you set the environment temperature set-point manually •...
6.1 Switched off (OFF) In this mode, the timer-thermostat is turned off and no adjustments are made; in this case, the icon is displayed above the temperature indicator. In this mode you cannot perform any operations other than activating the menus. Fig.
Fig. 15: 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 Auto This is the typical mode of operation of the timer-thermostat. The device automatically changes the ambient temperature according to the time of day and the day of the week, it minimizes user intervention thereby optimizing comfort and energy savings;...
6.4 Timed manual This mode allows you to temporarily exit the AUTO program (you enter MANUAL mode) for a certain time after which the timer-thermostat will return to AUTO mode. For example: take the ambient temperature to 25°C for 2 hours and then resume the Auto program. Activation is carried out starting from AUTO mode and is recognizable by the icon displayed above the temperature indicator.
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. 19: Input in away mode showing the away temperature Activation of this mode is identified by the icon above the temperature indicator: Fig.

For example: Before going to bed, using a simple switch, all the timer-thermostats in the house are set onto "reduction"...
In “Remote auto” mode, the timer-thermostat is activated in AUTO mode. In this condition, the display and the relevant buttons are not active; access to the settings menu is disa- bled and you cannot interact with the timer-thermostat (as it is controlled remotely). The "Remote auto"...

7.7 Temperature setting This menu lets you set the temperatures and hystereses necessary for defining the temperature control set-point used in the different operating modes. In particular, you can have setpoints for: : Away temperature (T away) * : Economy temperature (T economy) * : Comfort temperature (T comfort) * : external probe alarm temperature (if the external probe is configured as a "limitation") : hysteresis of the device (only if in OnOff adjustment mode)
7.7.4 External probe alarm temperature The menu, via , lets you set the temperature limit (read by the exter- nal probe) at which the timer-thermostat switches off the heating system and triggers an alarm. To view this menu, the external temperature probe must be set as a "limitation" (see par. 7.12.1).
7.9 External probe setting This menu lets you configure how to use the external temperature probe (installed according to the instructions in par. 4.2) you can select the following options: • OFF: the external probe (although physically present) is ignored by the device. •...
7.11 OnOff/PID temperature control algorithm setting This menu lets you select the way in which the ambient temperature will be controlled you can select the following options: • (OnOff control): this is the traditional "threshold" control so that, on exceeding the set temper- ature increased by (vice versa for air-conditioning), the heating is switched off to then be turned back on when the room temperature drops below the set temperature.
7.12.1 Configuring a phase to be measured To measure the power/voltage of phases 2 and 3 (or 1 if previously disabled) you need to enable them via this submenu and for each one of them set the calibration value of its current probe 01457.
