1. Thermostat 02905 The thermostat 02905 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.
3. Display The touchscreen display allows you to control the system using the following buttons and icons: Fig. 2: Graphical interface and buttons A: Battery charge status B: Operating mode C: Away D: Confirm E-F: Menu navigation and setting parameters G: Back H: Nighttime reduction I: Settings menu...
3.1 Functions of the buttons : increases the numerical values. When it "disappears" from the display it means that the value cannot be increased any more. : decreases the numerical values. When it "disappears" from the display it means that the value cannot be decreased any more.
3.3 Ecometer Energy saving indicator Ring for the level of consumption Fig. 3: 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 as an aid to energy saving. The information displayed is based on a consumption forecast obtained by comparing the currently set temperature setpoint and the estimated average consumption (which therefore has nothing to do with the current room temperature).
7. Operating mode The thermostat 02905 is able to adjust the temperature according to the following operating modes: • Switched off (OFF): switches the system off without making any adjustments • Manual (ON): lets you set the required temperature set-point manually •...
4.2 Manual (ON) This is the "traditional" operating mode. The thermostat controls the room temperature and takes it to the value set by the user. Fig. 6: Typical screen for Manual mode The set point can always be changed via In the course of setting, the set point flashes and the circular ring fills up accordingly;...
4.3 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 The Away mode can only be activated in manual mode by touching The display will show the "away temperature"...
4.4 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.
4.5 Antifreeze This mode, which can only be activated when the system is operating in heating mode, 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"...
4.6 Remote reduction Remote reduction is a useful way to "centralize" energy saving if there are multiple 02905 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.
4.7 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 (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.
5. Selecting user menu type and resetting default parameters Switch off the thermostat by removing the batteries and switch back on by replacing them; for approximately 3 s, the display will show the firmware version and the icon • Easy Menu Within 3 secs, touch and, using , select EASY and then YES confirming with...
6. Settings of the normal 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...
6.3 Heating/air-conditioning setting This menu is for the sole use of the installer. 6.4 Temperature set point setting This menu is for the sole use of the installer. 6.5 Multi-function input setting This menu is for the sole use of the installer. 6.6 OnOff/PID setting This menu is for the sole use of the installer.
