1. Timer-Thermostat 02910
Wall-mounting, battery-powered timer-thermostat with interface with capacitive keys and 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 (reduction, activation, summer/winter switching).
Can be connected, via circuit board 02915, to the energy probe 02960 (not supplied) for viewing consumption/
generation of electricity and corresponding historical data.
If the device is used in combination with the energy probe 02960 a built-in buzzer is available.
2. Field of application
The appliance is designed to control room temperature by acting on the control circuit of the burner or circu-
lation pump (heating) or on the control circuit of the air conditioner
(air conditioning), ensuring an ideal temperature.
The graphical user interface, thanks to special views, facilitates system management helping the user to oper-
ate while maintaining a state of energy saving.
Consultation of the energy consumption (or generation) carried out by connecting to the energy probe 02960,
lets you monitor up to 3 separate phases (with common neutral), for a maximum of 10kW per phase. The
device will not activate/deactivate loads, depending on the powers read (only monitoring with audible alarm,
if any).
3. Installation
The appliance must be installed on a wall at a height of 1.5 m off the floor in a suitable position for correctly
detecting the ambient temperature. It must not be installed in niches, behind doors and curtains or in areas
affected by sources of heat or atmospheric factors.
The timer-thermostat is a wall-mounting device that can be installed directly on a wall or on 2 and 3 module
back boxes.
It should be used in dry, dust-free places at a temperature between 0°C and +40°C.

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. The contact must be SELV and free of potential.
The typical wiring diagram is the following:

Activation type dry contact
Type of conductor 1 single wire or 1 multi-wire cable conductor
MAX. 1.5 mm2
Length of the conductor max. 100 m between the 2 terminals
4.3 Energy Probe 02960
For the timer-thermostat to be able to communicate with the energy probe 02960 it is necessary to use
the circuit board 02915 that is to be installed on the wall base.
Connect the circuit board 02915 and energy probe 02960 using a UTP CAT5E cable or better; the RJ9
phone connector for connecting to the probe must be wired in such a way as to have one pair of wires
between terminals 1 and 4 (outer pair) and the other between pins 2 and 3 (inner pair).
Take care to keep consistent connections at the terminals.

4.3.1 Measurement of 2 or 3 phases
The energy probe 02960 comes with a single current probe (for measuring the consumption/
production of a single phase); to measure more than one phase it is essential to have more
current probes 01457 (one for each additional phase to be measured). Once connected, you
must enable the new channel (the new phase to be measured) using the menu described
in par. 7.12.1.
4.3.2 Saving the consumption data log
In order for the energy probe to save the consumption data log properly, the latter must receive
the time setting from the timer-thermostat; then the clock must be correctly set (see par. 7.3). The
energy probe can save the consumption data log for a very long time (up to 3 years), provided
that its power supply is not interrupted for more than 7 consecutive days (at each start the time
must be reset by the timer-thermostat).
If the probe should remain switched off for over a week, the entire switch-off period would be
reduced in any case to a week (at most) with a loss of consistency in the log view; in this case,
to avoid inconsistent readings, you may want to reset its data log.
Here are some typical examples of installation of the energy probe:

6.1 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.
: during navigation, it scrolls the next item through the available menus. If it "disappears" then
you have arrived at the last of the items that can be scrolled.
: during navigation, it scrolls the previous item through the available menus. If it "disappears"
then you have arrived at the last of the elements that can be scrolled.
: 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. In addition, if
the timer-thermostat is connected to the probe 02960 via the circuit board 02915, it will also
be possible to enable its acoustic signal.
: 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.
IMPORTANT: In order to avoid any accidental modifications, first press and hold down the required
icon displayed to enable the function.

6.3 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.
Fig. 8: Locking with PIN
6.4 Alternative views
During normal operation, i.e. when you are not navigating the menus, you can select the information to
display on the left-hand side of the display.
If the right side always displays the measured temperature together with other data (which will be
explained below), tapping in succession the button on the left-hand side and in the program area
will display the two following options:
6.4.1 Clock, daily program and Ecometer
Fig. 9: Typical view of the time and daily program
This view is the default and gives an indication of the daily temperature control program along with
the data on the current moment.
The program area, represented by histograms, is divided into 24 sectors each of which repre-
sents the corresponding hour of the 24 hours in a day.
Energy saving indicator
Clock
Day of the week indicator
Set temperature indicator
Daily program

14
Each sector can be composed of 1, 2 or 3 dashes:
equivalent to “T away” ( )
equivalent to “T economy” ( )
equivalent to “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).
The set temperature indicator highlights the current temperature being regulated thus replicat-
ing the information represented by the “dashes”:
= T away
= T economy
= T comfort
The energy saving indicator indicates whether, compared to a conventional average consump-
tion, the set temperature setpoint enables you to achieve "savings" in consumption.
If the operating mode is not set on AUTO, the program area will not be active.
Fig. 10: Typical view of ecometer mode
The set of icons called "ECOMETER" provides a general indication of the expected consumption
facilitating energy saving.
The consumption forecast is given by a comparison between the currently set temperature value
and a conventional average consumption defined in the device.
• The ring of the level of consumption indicates the level of expected consumption; if the level is
less than half then savings are expected with respect to the conventional average consumption,
whereas if the level exceeds half then the expected consumption will be greater than average.
• The energy saving indicator indicates whether, compared to the conventional average con-
sumption, the set temperature setpoint enables you to achieve "savings" in consumption.

6.4.3 Consulting the energy probe (if enabled)
Fig. 11: Typical screen for consulting the energy probe
This option is used to consult data on the instantaneous power and energy consumed/generated
by the system and measured instantly by the energy probe.
CAUTION: Proper operation and proper consultation require:
• The energy probe 02960 to be powered and functioning
• The energy probe 02960 is properly interconnected with the circuit board 02915
• The clock of the timer-thermostat to be set correctly
If these conditions are met, the indicator LED of the energy probe 02960 will flash "slowly"
(1 flash every 2 seconds approximately).
The measured power is the value measured by the energy probe 02960; the value shown is the
sum of the (active) powers of all the active channels of the probe (eg, all 3 channels could be
active, or only channel 1 or channels 1 and 3, etc.).
The unit of measurement (W or kW) is displayed under the measured value.
• If the sum of the powers turns out to be consumed (i.e. absorbed by the energy supplier), the
value is positive and the generation/consumption indicator is off.
• If the sum of the powers turns out to be generated (for example, the photovoltaic system is
supplying power to the electricity grid), the value is negative and the generation/consumption
indicator is on.
When consulting the power/energy data, the "consumption log" view provides a rough estimate
of the consumption recorded in the last period. In particular, each horizontal group of dashes rep-
resents the year/month/day/hour depending on whether the word displayed is YEARS/MONTHS/
DAYS/HOURS respectively.
The current year/month/day/hour is highlighted by the group of flashing dashes while the
previous and the next are represented by groups of dashes shown respectively to the left and
right of the flashing group.

16
The information provided is represented as follows:
indicates consumption less than half the average consumption
indicates consumption in line with the average
indicates consumption 1.5 times higher than the average
The circular ring (only when consulting the instantaneous power) represents the current level of
consumption compared to the maximum level recorded in the last 24 h (ring complete with all the
dashes = maximum consumption); the number of dashes can therefore vary even if the power is
the same since what is displayed depends on the consumption log.
Pressing and holding the central area (see fig.7), instead of the instantaneous power, displays the
energy consumed (or generated) during the current day; in this case the circular ring represents
the level of consumption of the current day compared to the last 30 days. If the dashes reach
halfway around the ring it means that the consumption in the last 24 hours is in line with that of
the last 30 days; vice versa, if the dashes exceed or are less than half of the ring it means that the
current consumption is respectively higher or lower than the average of the last 30 days.
6.4.3.1 Consulting the energy log
Touching displays the historical data on energy consumption measured and saved
by the energy probe 02960.
Fig. 12: Typical view of historical energy data consultation
Via and and confirming with you set the range of historical consump-
tion that you want to see:

17
• (historical data reset): this option lets you delete ALL the historical data saved
by the energy probe; since this operation cannot be undone, an additional confirmation
screen is displayed (YES to delete and NO not to delete).
• (hourly consumption): enables you to scroll one by one through the hours prior to
the current one; the indices range from “0h” (current hourly consumption) to “-23h”
(hourly consumption of 23 hours ago).
• (daily consumption): enables you to scroll one by one through the days prior to the
current one; the indices range from “-0D” (current daily consumption) to “-30D” (daily
consumption of 30 days ago).
• (monthly consumption): enables you to scroll one by one through the months prior to
the current one; the indices range from “-1M” (monthly consumption of the last month)
to “-11M” (monthly consumption of 11 months ago).
N.B.: Monthly consumption (or generation) is considered to be the consumption (or
generation) recorded in a fixed period of 30 days. The month “-1M” therefore represents
the consumption recorded in the period from 30 days ago until yesterday. The month
“-2M” represents the consumption recorded in the period from 60 days ago until 31
days ago, etc.
• (yearly consumption): enables you to scroll one by one through the years prior to the
current one; the indices range from “-1Y” (yearly consumption of the last year) to “-3Y”
(yearly consumption of 3 years ago).
N.B.: Yearly consumption (or generation) is considered to be the consumption (or
generation) recorded in a fixed period of 365 days. The year “-1Y” therefore represents
the consumption recorded in the period from 365 days ago until yesterday. The year
“-2Y” represents the consumption recorded in the period from 730 days ago until 366
days ago, etc.
Confirming the selection will then display the energy consumed or generated in Wh or
kWh. Obviously, if the energy probe was installed at a time when there were not yet any
data for the period of consultation, the historical energy data will be 0.
For example, if the probe was installed 20 days ago and we are consulting the term "-3
months" then the consumption is obviously 0 Wh.

7. Operating mode
The timer-thermostat 02910 is able to regulate 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
• AUTO: lets you set a control program that compares the room temperature with the value set for each
quarter of an hour of the current day; the user defines three levels of temperature distributed over 24 hours
which can then be varied for each day of the week.
• Timed manual: starting from AUTO mode, this lets you activate MANUAL operation of the timer-thermostat
for any period of time at the end of which the device will return to AUTO mode.
• Away: lets you set the set-point in order to achieve significant energy savings during periods when the user
is away
• Antifreeze: used to set a minimum temperature level to avoid damage to pipework or prevent the temper-
ature from falling below a safety level.
In addition, if the multi-function input of the timer-thermostat has been suitably configured, you can remotely
activate the following modes:
• Remote reduction: lets you vary the set points of MANUAL adjustment to obtain energy savings.
• Remote activation: lets you activate the system remotely, setting AUTO operation.
• Summer/Winter switching: the multi-function input automatically switches the timer-thermostat onto
air-conditioning mode (when on) or heating mode (when off).
The operating mode is selected via the SETTINGS menu or with the shortcut keys.
7.1 Switched off (OFF)
With this mode on, the timer-thermostat is turned off and you cannot make any adjustments; in this case,
the icon is displayed above the temperature indicator.
In this mode you cannot perform any operations other than activating the menus or changing the view
mode.
Fig. 13: Typical screen for OFF mode
For heating-only systems this mode is typically used in the summer.
