1. Timer-Thermostat 02955

Recessed timer-thermostat (3 modules, for use with the Plana, Eikon and Arkè series) on AC power, with mul­ti-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 temper­ature 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 circu­lation 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 oper­ate 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.

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 inad­vertent 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

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 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 (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 consump­tion 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 colour1 of the display may also vary, providing an indi­cation of the expected consumption associated with the setting being made:

green yellow red

loptimum consumption excessive consumption

1 Only 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).

19

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.

Fig. 17: Input screen in Timed Manual mode

Using and you set the temperature and confirm with .

The next screen, again using and , lets you set the time for which the temper­ature you have just set is maintained.

Fig. 18: Regulating the number of hours of Timed Manual mode

Finally confirm with .
At the end of the set time the timer-thermostat goes back into AUTO mode, the icon switches off
and reappears.

6.5 Away

This mode is useful to achieve energy savings quickly and effectively whenever the user leaves the reg­ulated room.
In "Away" mode the system makes the adjustment according to the "away temperature" setpoint .

20

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. 20: Away Mode

To exit and return to the previous mode touch the button again:

6.6 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" mode is activated directly from the Settings menu.
Once activated, antifreeze mode is identified by the icon above the temperature indicator.

21

Fig. 21: Antifreeze mode

6.7 Remote reduction

Remote reduction is a useful way to "centralize" energy saving if there are multiple 02955 timer-thermo­stats in different rooms of the same house.

For example: Before going to bed, using a simple switch, all the timer-thermostats in the house are set
onto "reduction" at the same time.

This mode comes into operation when the multi-function input is activated (see par. 4.1) only if it
has been properly configured; activation of the multifunction input is acknowledged solely when
the timer-thermostat is in Manual mode.

In "remote activation" mode, the device sets the temperature to a value equal to Tcomfort- .

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:

1. and : Away temperature (T away) *

2. and : Economy temperature (T economy) *

3. and : Comfort temperature (T comfort) *

4. and : external probe alarm temperature (if the external probe is configured as a "limitation")

5. : hysteresis of the device (only if in OnOff adjustment mode)

6. and : thermal delta in remote reduction mode *

7. and : “antifreeze” mode temperature (only if in “heating” mode)

* CAUTION: Depending on the mode the thermostat is in (heating or air-conditioning), setting this
setpoint acts only on the value associated with the current mode highlighted by the or icon
(for example, heating mode).

After then changing the setpoints of the current mode in succession, change the mode (see 8.3)
and set all the setpoints corresponding to it (for example, air-conditioning mode).

7.7.1 Away temperature

The menu, via and , lets you increase/decrease the value of the away
temperature or .
The away temperature is an intermediate temperature between that of Manual and Antifreeze
mode, geared to obtain substantial energy savings during periods when the user is away.
The away temperature differs depending on whether you are in heating mode (in which T.away is
less than Tcomfort) or air-conditioning mode (in which T.away is greater than Tcomfort).

7.7.2 Economy temperature

The menu, via and , lets you increase/decrease the value of the econ­omy temperature or .
The Teconomy temperature allows energy savings if applied during the nighttime (when it is point­less and costly to maintain the same setting as the daytime hours).
The economy temperature differs depending on whether you are in heating mode (in which
T.economy is less than Tcomfort) or air-conditioning mode (in which T.economy is greater than
Tcomfort).

7.7.3 Comfort temperature

The menu, via and , lets you increase/decrease the value of the comfort
temperature or .
The Tcomfort temperature can be defined as the "comfort temperature" that you want to reach
during the hours when people are present in the rooms of the dwelling.
The comfort temperature differs depending on whether you are in the heating or air-conditioning
mode.

27

7.7.4 External probe alarm temperature

The menu, via and , lets you set the temperature limit (read by the exter­nal 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).

7.7.5 Hysteresis of the device

The menu, via and , lets you set the temperature range of the heating/
air-conditioning 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 timer-thermostat is set as PID operation.

For example: Heating, with setpoint on 20.0°C, : 0.5°C    20.5 (off), 20.0 (on)

7.7.6 Thermal delta in nighttime reduction mode

The menu, via and , lets you set the difference between the remote
reduction temperature and Tcomfort temperature.

The remote reduction mode can only be activated via the multi-function input (if configured
appropriately - see par. 7.10).

The hysteresis is a temperature increase/decrease that is applied to the Tcomfort temperature
when the multifunction input is activated). The value of the thermal delta is identical in both heating
and air conditioning with the only difference being that in the former case it determines a decrease
in the set point while in the latter case it determines an increase.

7.7.7 Antifreeze temperature

The menu, via and , lets you increase/decrease the value of the anti­freeze temperature or .
Antifreeze mode is used to set a minimum temperature level to avoid damage to the pipework or
keep the room temperature from falling below a safety level.

7.8 Calibration setting

This menu lets you "calibrate" the temperature read by the timer-thermostat.
Using and , you can add or subtract (at intervals of 0.1°) a fixed amount from
the temperature detected by the timer-thermostat to make it equal, for example, to that of a sample
thermometer.

CAUTION: For correct calibration it is recommended to wait until the timer-thermostat has been on
for at least 1 hour in a room at constant temperature.

Tap

to confirm your choice.

28

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)

Via and you can select the following options:

• OFF: the external probe (although physically present) is ignored by the device.

• Adjustment (the measured temperature flashes): by enabling this function, the thermostat will regu-

late the temperature of the environment based ONLY on the temperature detected by the external probe
(the temperature measured by the thermostat is ignored).
The temperature shown on the display will be that of the external probe identified by the icon.

• Display (the temperature measured by the thermostat and that of the external probe are shown
alternately on the display): the external probe is only used to display the temperature in another
environment.
On standby the display will alternate views of the internal temperature (measured by the thermostat) and
external temperature (measured by the probe) and identifiable by the icon.

• Limitation (the flashes): mode used to protect underfloor heating systems.
In the associated submenu you set the limitation temperature that is the one, read by the external probe
immersed in the screed, that is considered an excessive temperature (dangerous). If this threshold
temperature is reached the timer-thermostat turns off the heating system and displays the alarm accom­panied by an audible warning as long as the dangerous condition remains.
At the end of this condition, the timer-thermostat resumes its normal operation.

Tap to confirm your choice.

7.10 Multi-function input setting

This menu is used to set the operating mode of the multi-function input.
Via and you can select the following options:

• OFF: the state of the multi-function input is ignored by the device.

• (Remote auto): the multi-function input (when enabled) activates the timer-thermostat in

“Auto” mode. In this situation the user cannot carry out any operations on the device other than con­sult the main screen; with the multi-function input disabled, the default mode is "Antifreeze" (or OFF if
on air-conditioning) and the user can manage the timer-thermostat completely.

• (remote reduction): the multi-function input (when enabled) forces a reduction in temperature

(which can be set via the submenu associated with that selection) with respect to “Tcomfort”.
In this situation the user cannot carry out any operations on the device other than consult the main
screen; with the multi-function input disabled, the timer-thermostat goes back into manual mode and
the user can manage the device completely.

• (summer/winter switching): the multi-function input automatically switches the timer-thermostat

onto air-conditioning mode (when on) or heating mode (when off).

This option is useful for centralized systems in which the air-conditioning or heating mode is performed
at the level of the entire building and impacts on many sub-environments.

Tap to confirm your choice.

29

7.11 OnOff/PID temperature control algorithm setting

This menu lets you select the way in which the ambient temperature will be controlled
Via and 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.
The value can be set directly via the submenu that follows this selection.

• (P.I.D. control): this is an evolved algorithm that is able to keep the temperature in the envi­ronment more stable, increasing comfort; this algorithm switches the system on and off appropriately
so there will be a gradual increase or decrease in the thermal (or refrigerating) power of the system
itself.
To take full advantage of its performance it needs to be suitably calibrated according to the type of
environment and heating system; in the light of this, the following parameters must be set via the
submenus that follow this selection:

• (temperature of proportional band): starting from the set temperature, Tb is the temperature

range in which the heating power goes from 0% to 100%.

For example: with the temperature (for heating) set to 20.0°C and Tb=4.0°C, the thermostat acti­vates the heating system on 100% when T.ambient is <= 16.0°C; as this temperature increases,
the system power is consequently lowered down to 0% when the ambient temperature reaches
20°C.

The value of Tb must be set consistently with the thermal capacity of the system; in general, it is
recommended to use small values of Tb for environments with a good level of thermal insulation
and vice versa.

• (system cycle time): this is the time in which a cycle of regulation is completed; the shorter

this time, the better the regulation but the temperature control system is under greater stress.
This parameter setting is thus the result of a compromise between the accuracy of the regulator
and the load on the system; in general, the rule is that Tb can be that much higher (and there­fore put fewer demands on the system), the slower the system or the larger the environment to
regulate.

Tap to confirm your choice.

7.12 Energy probe setting

When the energy probe is connected to the device, the menu allows you to enable or disable the meas­urement of each phase or configure the "power threshold" alarm.
There are the following submenus:

• If “P1”, “P2” and “P3” blink it is possible to enter the submenu for configuring phases 1, 2 and 3 of
the energy probe.

• If the and ”kW” icons blink it is possible to enter the "power threshold" alarm submenu.

30

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.

• With confirm the selection of “P1”,“P2”or“P3”, using and

you can enable or disable the respective phase by selecting ON or OFF and

confirming with .

• After the above setting, if the channel is enabled, the display will prompt you to enter the

3-digit number printed on the label applied to each probe 01457 (for example, 12B); using

, and confirming with enter the 3 digits one at a time.

Note: If the channel (1 or 2 or 3) is disabled, the probe will ignore the voltage/power value meas­ured by that channel; so even if physically there is a power other than 0 which runs through the
disabled phase, the probe will still display the value 0.

7.12.2 Configuring the “power threshold” alarm

The menu lets you set an overall power level (i.e. the sum of all 3 channels) read by the energy
probe and on exceeding which the timer-thermostat will emit an audible "alarm" warning. This
feature is useful to warn the user of exceeding a defined consumption threshold and give her the
chance to intervene by turning off the source of excessive consumption. This will help to avoid
potential disconnection from the mains supply or to optimize power consumption according to
need.
The alarm remains active as long as the measured power remains above the alarm level and stops
when it falls back below that level.

Confirm with

.

7.13 Buzzer (beep) setting

This menu lets you enable/disable the acoustic signals of the timer-thermostat; if it is disabled there will
no longer be any sound when you touch the buttons or in cases of confirmation/error.

Whereas, in the event of an alarm, the sound signal will always be guaranteed.

Using and select “ON” or “OFF” and confirm with .

7.14 Setting the display colour

This menu is used to select the background colour of the display.

In addition to the four default colours, you can set a colour to your choice selected from the full range of
colours, or set "ECO" mode in which the display colour is a clue to the expected level of consumption
in the building.

Via and you can select:

• : white default colour

• : colour matching the Plana series

31

• : colour matching the Eikon series

• : colour matching the Arkè series

• (custom colour): takes you to another menu and via and you set

a custom colour; while the numbers scroll, the display shows the corre­sponding colours in real time.

• : ECO mode allows displaying a colour that, depending on the set temperature, is associ-

ated with the expected level of energy consumption. Specifically:

green yellow red

optimum consumption excessive consumption

ECO mode therefore does not display the colour as a function of the temperature measured at that
time but only in relation to the set point.

Lastly, tap to confirm your choice.

7.15 Standby brightness level setting

The menu lets you set the brightness level when the thermostat is in standby mode.
Via and select one of the following levels with gradually increasing brightness:

•

•

•

•

While scrolling through the values, when the selection stops on a certain level, the brightness of the
display will, for approximately 2 s, take on the brightness corresponding to the selected level in order to
allow the user to check the visual effect.

Lastly, tap to confirm your choice.

32

7.16 Info about the device

This menu lets you view information related to the thermostat and reset the device.
Via and you can select:

• : displays the number of hours that the timer-thermostat relay has been on (the same as the number
of hours of operation of the heating/air-conditioning system).
The counter can be reset, for example at changes in season to differentiate between heating and
air-conditioning, by pressing and holding the middle of the display.

• : displays the software version of the device.

• : deletes all the settings made (temperatures, colours, etc.) and returns the device to the factory
default values. The settings for the energy probe 02960 (if installed) are not deleted.

• : displays the voltage measured in the phases of the energy probe 02960; U1, U2 and U3 indicate
the voltages read in the respective phases 1,2,3.

• : displays the active power measured in the phases by the energy probe 02960; P1, P2 and P3
indicate the powers read in the respective phases 1,2,3.
This view lets you see the consumption or production of each single phase rather than the sum of all
three as a single value.

7.17 Lock/unlock PIN setting

This menu lets you add/change the password to inhibit use of the thermostat.
Using and set the three digits of the PIN one at a time and then confirm each

set digit with .
If you wish to have free access to the thermostat (so without it prompting you for a password) it is suf-

ficient to set the PIN to “000”.

To reset your PIN, if you forget the value you entered, proceed as follows:

1. Cut off power to the timer-thermostat

2. Do not power it until it loses the time setting (this may take some hours)

3. Power up the timer-thermostat again

4. Within the first 30 s, i.e. before going into Standby mode, go to the PIN menu and enter the new value.
