INSTALLATION AND CONNECTIONS

SAFETY INSTRUCTIONS

Before connecting the programmable thermostat, make sure that the electric power supply IS NOT SWITCHED ON and that its voltage

corresponds to the one mentioned on the appliance ( 230V~) (fig. 4)

PLACEMENT OF THE THERMOSTAT

Install the thermostat far from heat sources (radiators, direct sunlight and kitchens) and far from doors/windows, etc. To ensure its

correct operation, it is very important to place the thermostat at approx 1,5 m height above the floor and on interior walls; it is also

recommended to seal the conduit outlet of the boiler electrical wires. (fig. 5)

INSTALLATION

The thermostat unit is supplied completely assembled and already fitted in the suitable standard FRAME. Therefore the installation

is very simple and can be easily performed as follows:

Connect all the wires to the terminals as per the “wiring connections” paragraph below.

Insert the thermostat (with the relevant FRAME) in the 3-module standard built-in box, already fitted to the wall, and tighten it with

the screws provided. Fit the selected COVER PLATE in its correct position (fig.6)

PLATE POSITIONING

The particular design of the thermostat FRAME allows the fitting of different COVER PLATES, namely:

Bticino “LIVING INTERNATIONAL” plate

Gewiss “PLAYBUS” and “PLAYBUS YOUNG” plates

Vimar “IDEA” and “IDEA RONDÒ” plates

When fitting a “LIVING INTERNATIONAL” or “PLAYBUS”/”PLAYBUS YOUNG” plate, the side tabs on the FRAME should be broken off

and removed. (fig.7)

When fitting an “IDEA” or “IDEA RONDÒ” plate, the FRAME should not be modified and the side tabs should not be removed from

the FRAME. (fig.8)

NOTE: Two plastic strips are always provided with the device. When fitting Gewiss or Vimar plates, these strips may be used as

outside coverings to hide holes that may be visible on the front of the thermostat unit after its assembling.

WIRING CONNECTIONS

Connect the appliance power supply wires to terminals n° 4 and n° 5 located on the back side of the thermostat; the wires of the

UNIT TO BE CONTROLLED should be connected to terminals n° 1 and n° 2, as per the wiring diagram in fig.9.

U = unit to be controlled

1 = common contact

2 = normally-open contact

3 = normally-closed contact

4÷5 = power supply contacts

THERMOSTAT START-UP

When the appliance has been connected and the power supply has been switched on, all available segments and symbols will then be

displayed for a few seconds (AUTOTEST). The programmable thermostat is now ready for:

• CLOCK SETTING (time/day)

• TEMPERATURES SETTING

• AUTOMATIC MODE operating as per the preset program (if time/day setting have been configurated)

or

• OFF MODE (if time/day setting has not been configurated)

CLOCK SETTING (time/day)

This function is active in all three operating modes (AUTO, MAN, OFF).

Setting procedure

• Press once key “TIME SET”

The display shows the clock figures for HOURS (blinking), MINUTES and the symbol " " indicating the day of the week (at the beginning

it is pointing to MONDAY). (Fig.10).

• Press “–/+“ several times or continuously to set the HOUR (if pressed uninterruptedly the figures decrease/increase automatically and

gradually and stop blinking).

• Press once “TIME SET” ( ) to confirm the HOUR setting and to store it in the unit memory; the display will then show the MINUTES

figures (blinking). (Fig.11).

• Press “–/+“ several times or continuously to the MINUTES.

• Press “TIME SET” ( ) to confirm the MINUTES setting and to store it in the unit memory; the display will then show a blinking the

symbol “ ” indicating the day of the week. (Fig.12)

• Press “–/+“ several times or continuously to set the current DAY OF THE WEEK.

• Press “TIME SET” ( ) to confirm the DAY setting and to store it in the unit memory.

This concludes the CLOCK SETTING procedure and starts the operating TEMPERATURE SETTING procedure.

SUMMER/WINTER SETTING

The programmable thermostat can be programmed for “summer” ( ) or “winter” ( ) operation, depending on whether it is connected

to an air-conditioner or a boiler.

Setting procedure

• Use a pencil point to press the E/I key. Each time the key is pressed, the display will alternately show the symbol ( ) (air conditioning)

or ( ) (heating).

TEMPERATURE SETTING ( )

The programmable thermostat is provided with 2 TEMPERATURE LEVELS:

T

1

(

comfort

) = Ideal temperature when stay at home.

T

2

(

reduced

) = Temperature for night-time or periods during nobody stay at home (when the user is at work for several hours, etc.)

These temperature levels may be adjusted by the user and are factory pre-set and stored as follows:

T

1

= 20°C (COMFORT temperature)

T

2

= 16°C (REDUCED temperature)

If the above temperature levels need to be modified, it is very important to note that the lower temperature shall always be assigned to T

2

and the higher temperature to T

1

.

TEMPERATURE SETTING LIMITS

T

1

= starting from T2 up to 38° C

T

2

= starting from 6°C up to T1

Setting procedure

Press the MODE key to activate the AUTO mode.

The time, day of the week and activated mode (AUTO) are displayed.

Press key, the symbol “ ” and relative value set for this temperature T

1

will blink on the display.(Fig.13).

Press the keys – or + to decrease or increase the set value. Press the key “ ” , to store the value T

1

.

At this point the symbol “ ” and relative value set for this temperature T

2

will blink on the display.

Press the key “ ” to confirm the value of T

2

and exit the temperature setting procedure.

Press the keys – or + to decrease or increase the set value.

If, on the contrary, NO modifications are desired, press the key to confirm the pre-set temperature values for T

1

and T

2

(once to confirm T

1

and then again to confirm T

2

). (Fig.14).

Press the key “ ” , to store the value T

2

and to complete temperatures setting.

PROGRAM SETTING

A PRE-SET PROGRAM is stored in the unit memory (see the paragraph TECHNICAL DATA).

Make certain that the AUTO mode has been activated (see the Thermostat Control Keys paragraph).

During the PROGRAM SETTING procedure, the pre-set program chart will be displayed. This chart is composed of “ ” corresponding to

each programming period (1 hour), shown in the lower position if the reduced temperature is to be maintained during this period or in the

upper position if the comfort temperature is to be maintained during this period.

MODIFICATION OF THE PRE-SET PROGRAM

The example provided below is based on the factory pre-set program.

Setting procedure

During the 24h programming procedure, the clock does not indicate the current time but helps the user identify the start of the active period

indicated by the blinking the symbol " " .

• Press the PROG key to start the program modification procedure.

• The symbol “ ” pointing to Monday “1” and the symbol “ ” pointing to the “zero” hour (0) in the time/temperature chart will start

blinking. The display will also show the symbol “ ” since the symbol “ ” corresponding to the blinking time period is in the lower

position. (Fig.15). Each time the key “ ” is pressed, the symbol “ ” will alternate its position enabling the corresponding temperature

reference (low = reduced, high = comfort), shifting to the next hour to the right.

• If instead it is desired to set directly the programming of a specific day, press the PROG key repeatedly until the active day symbol

( ) blinks on the display.

• Press the –/+ keys to move HORIZONTALLY on the chart and set the next operating period.

• Follow the same procedure to program all 24 hours of the time/temperature chart.

• At the end of the chart definition regarding Monday “1”, press PROG to confirm the programming and move to the following day of the

week: the symbol “ ” pointing to Tuesday “2” and the symbol “ ” pointing to the “zero” hour (0) will now start blinking.

Set the time/temperature chart for Tuesday and the remaining days of the weeks following the same procedure.

• When the setting procedure is completed and the symbol “ ” is blinking pointing to Sunday “7”, press the PROG key to CONFIRM

and ACTIVATE the program just set.

AUTOMATIC MODE (AUTO)

NORMAL OPERATION CONDITIONS (Fig. 16)

During normal operation, the following are displayed:

4 The symbol of the set temperature presently ACTIVATED

4 The operating program chart with the relevant temperature level presently ACTIVATED (T

1

or T

2

)

4 the symbol ( ) or the symbol ( ) for summer or winter operation mode

4 the symbol ( ) indicating that the boiler or air-conditioner are operating

When the AUTOMATIC mode is selected, the programmable thermostat will manage the room temperature following the set program.

TEMPORARY MODIFICATION OF THE TEMPERATURE (Fig. 17)

With the AUTO mode activated, the temperature can be temporarily modified for a period of the program.

Press the – or + key once and the pre-set temperature T1 COMFORT to be maintained will blink on the display. Use the – and + keys to

set a new temperature value. If no key is pressed within about 8 seconds, the set value will be stored.

The segments corresponding to the part of the program that has been temporarily changed will blink on the display.

The programmable thermostat will return operating in AUTO mode at the next temperature change in the program. The temporary change

can be cancelled by pressing the MODE key.

MANUAL MODE

When the MAN mode is selected using the MODE key, the programmable thermostat will exclude the set program and operate as a simple

manual room thermostat, maintaining the room temperature at the set value during each hour of the day.

The pre-set temperature (20°C) to be continuously maintained will blink on the display (for about 8 seconds if it is not changed). A new

temperature value can be set using the – and + keys.

This value will continue to blink for another 8 seconds after which the display will resume showing the actual room temperature.

To display the value of the set temperature at any time, press the – and + key just once. Pressing the key again will change the value of

the temperature. To exit the MAN (manual) mode, press the MODE key and return to operation in AUTO mode.(Fig. 18)

OFF MODE (Fig. 19)

The OFF mode activates the ANTIFROST protection.

The programmable thermostat will manage the room temperature so that it does not fall below 6°C, thus protecting pipes from freezing during

long periods out of home. The display shows the actual room temperature, clock, activated mode (OFF) and the ANTIFROST symbol ( ).

USEFUL INFORMATION AND WARNINGS

f

When FIRST installing the unit, in case only the CLOCK SETTING procedure is carried out, the appliance will start normal operation,
