Page 4: Timer-Thermostat 02905
1. Thermostat 02905 Wall-mounting, battery-powered thermostat with interface with capacitive keys. Equipped with user-friendly functions to facilitate energy saving. Designed to control heating and air-conditioning via C, NC, NO relay output. Equipped with multi-function input for remote control. 2. Field of application This device 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. -
Page 5: Multi-Function Input
4.2 Multi-function input Depending on how it is configured, the multi-function input can be used to activate various functions of the timer-thermostat (see par. 7.8 and 7.9). It is on when the two terminals of the figure are closed by a dry contact; vice versa if they are open, the input is off. -

6.3 Ecometer Energy saving Ring for the level of consumption indicator Fig. 6: 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). -
Page 10: Operating Mode
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 •... -
Page 11: Manual
7.2 Manual (ON) This is the "traditional" operating mode. The thermostat controls the room temperature and takes it to the value set by the user (manual adjustment setpoint). Fig. 9: 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;... -
Page 12: Away
7.3 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. 9.4.2). The Away mode can only be activated in manual mode by touching The display will show the "away temperature"... -
Page 13: Nighttime Reduction
7.4 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. -
Page 14: Antifreeze
7.5 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"... -
Page 15: Remote Reduction
7.6 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. -
Page 16: Remote Activation
7.7 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. -

9.3 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 required operation and confirm with 9.4 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. -
Page 20: Away Temperature
9.4.2 Away temperature This menu, via , lets you increase/decrease the value of the away temperature The away temperature, preset by the user, is an intermediate temperature geared to obtain sub- stantial energy savings during periods when the user is away. The away temperature differs depending on whether you are in the heating or air-conditioning mode. -
Page 21: Hysteresis Of The Device
9.4.6 Hysteresis of the device This menu, via , lets you set the temperature range of the heating/air-condition- ing system between "ON" and "OFF". This value can also be changed via the submenu for ON/OFF operation. The parameter cannot be changed if the thermostat is set as PID operation. For example: Heating, with setpoint on 20.0°C, : 0.5°C ... -
Page 22: Onoff/Pid Setting
9.7 OnOff/PID 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 tem- perature 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. -

9.8 Info The menu lets you view information related to the thermostat. Using you can select: • : displays the number of hours that the thermostat relay has been on (the same as the number of hours of operation of the system). The counter can be reset, for example at changes in season to differentiate between heating and air-conditioning, by pressing and holding the button. -
