1. Timer-Thermostat 02955
Recessed timer-thermostat (3 modules, for use with the Plana, Eikon and Arkè series) on AC power, with mul-
ti-colour display and interface with capacitive buttons. Equipped with user-friendly functions to facilitate energy
saving. Designed to control heating and air-conditioning via C, NC, NO relay output. Built-in audible warning.
Programmability facilitated with smartphone app, available for iOS®, Android®and WindowsPhone®.
Equipped with a multi-function input for remote control and an input for management of an external temper-
ature probe (not supplied).
Can be connected to the energy probe 02960 (not supplied) for viewing consumption/generation of electricity
and corresponding historical data.
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 energy 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 viewing with audible alarm,
if any).
The smartphone app enables facilitating device configuration, programming it with an acoustic signal. The
settings of the timer-thermostat cannot be read by the smartphone, but only set with it.
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.
It can be fitted on the mounting frames of the Plana, Eikon and Arkè series. Size: 3 modules.
It should be used in dry, dust-free places at a temperature between 0°C and +40°C.
4. Connections
4.1 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. 7.10).
It is active if terminal "IN" is connected to the system live "L"; if it is not connected or connected to neutral
"N", the input is disabled.

Length of the conductor max 100m between “L” and “IN”
4.2 External temperature probe
Depending on how it is configured, the external temperature probe can be used to accomplish several
functions (see par. 7.9); it does NOT have polarity so you can connect the 2 wires in the 2 terminals
without any particular order.
It is recommended to use the NTC 10k beta 3900 probe (art. 02965.1 or art. 20432-19432-14432).
The terminals of the temperature probe and the connector for connecting to the energy probe are
to be considered SELV parts.

IMPORTANT: During installation, take care not to damage the insulation of the probe while
laying the screed. Perform the installation in such a way that the probe is accessible for any
maintenance work.
4.3 Energy Probe 02960
Connect the timer-thermostat and energy probe 02960 using a UTP CAT5E cable or better; the RJ9
phone connector 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). The connection between the devices must
be a NON-CROSS connection, that is the layout of the conductors on the two sides must match.
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 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:

5. Display
The touchscreen display allows you to control the system using the following buttons and icons:
Fig. 7: Graphical interface and buttons
5.1 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 through the available menus. If it "disappears" then you have
arrived at the first of the elements that can be scrolled.
: during navigation, it scrolls 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 and (if
enabled) the relevant 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.

• 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.
• To exit standby mode, press the middle of the display; the increase in the level of brightness of the
device and the appearance of active buttons will confirm the restoration of normal functions (if enabled,
there will also be an audible "unlock" signal)
5.2 Symbols
Depending on the different operating modes, the display shows the following icons:
: Calibration
: Entering the PIN
: Timed manual operation
: Away
: Manual
: Nighttime reduction
: Antifreeze
: OFF
: Automatic operation
: Multi-function input ON
: External temperature probe
: Alarm

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.
Fig. 8: Locking with PIN
5.4 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 the central area of the display on the left-hand side in succession will
display the three following options:
5.4.1 Clock and daily program
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 circular ring icon which represents the program is divided into 24 sectors, each of which
represents one hour of the day; the wedge in the middle at the top represents the time 12:00.
Circular ring of the daily program
Clock
Energy saving indicator
Day of the week indicator
Set temperature indicator

13
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).
The set temperature indicator highlights the current temperature being regulated thus replicat-
ing the information represented by the “dashes”:
= T away
= T economy
= Tcomfort
If the operating mode is not set on AUTO, the ring will be a circular icon with no "dashes" as there
is no active temperature control program and so there will be no set temperature indicator visible.
5.4.2 Ecometer
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 an "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 "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 an average consumption, the set
temperature setpoint enables you to achieve "savings" in consumption.

5.4.3 Consulting the energy probe (if enabled)
Fig. 11: Typical screen for consulting the energy probe
This view is used to consult data on the instantaneous power and energy consumed/generated
by the system and measured by the energy probe.
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"
(1 flash every 2 seconds approximately).
The measured power is the value measured by the energy probe; 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.
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.

5.4.3.1 Consulting the energy log
Touching displays the historical data on energy consumption measured by
the energy probe.
Fig. 12: Typical view of historical energy data consultation
Via and and confirming with you set the range
of historical consumption that you want to see:
• (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 the data and NO not to delete them).
• (hourly consumption): enables you to scroll one by one through the hours prior to the
current one; the indices range from “0h” (hourly consumption of 1 hour ago) 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” (daily consumption of 1 day ago) 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 (it does not therefore correspond to a
"calendar" month). The month “-1M” therefore represents the consumption recorded in
the period from 30 days ago until yesterday. The month “-2M” represents the consump-
tion 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 gen-
eration) recorded in a fixed period of 365 days (it does not therefore correspond to a
"calendar" year). 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

16
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.
In addition to the numerical data, the circular ring gives an idea of the current consump-
tion compared to that of the previous hours/days/months/years.
The dashes reach halfway around the ring when the consumption of the current day/
month/year is in line with that recorded in the corresponding previous periods (the last 24
hours for the hour, last 30 days for the day, last 12 months for the month and last 3 years
for the year). Conversely, if the dashes exceed or are less than halfway around the ring it
means that the current consumption is respectively higher or lower than the average of
the relevant periods (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
• AUTO: lets you set a control program that compares the room temperature with the value set for each 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.
The operating mode is selected via the SETTINGS menu (see chap. 7).

17
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. 13: Typical screen for OFF mode
For heating-only systems this mode is typically used in the summer.
6.2 Manual
In this mode the device operates as a simple thermostat that regulates the ambient temperature, taking
it to the value set by the user.
When MANUAL mode is active, the icon is displayed above the temperature indicator.
Fig. 14: Typical screen for Manual mode
The set point can always be changed via or .
In the process of setting, the set point flashes; the colour1of the display may also vary, providing an indi-
cation of the expected consumption associated with the setting being made:
green yellow red
loptimum consumption excessive consumption
1Only if the colour set for the display is white (C0) or ECO, see par. 8.9.

18
Fig. 15: Manual set point setting
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).
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; three different
temperatures can be set to cover the needs of normal use, user away or nighttime reduction in the
environment.
For setting the automatic program, see par. 7.6.
When AUTO mode is active, the icon is displayed above the temperature indicator.
Fig. 16: Typical screen for Auto mode
By touching and you can temporarily change the ambient temperature, setting
it to a different value to the one associated with the current time slot.
Confirming with it then goes into TIMED MANUAL mode (see par. 6.4).
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).
