Installation

Positioning

The position in which the thermostat is installed can have a significant impact on its performances.
The device must be installed on the internal wall of a room where you usually spend your time, away from draughts (doors, windows, fans, etc.), sources of heat (radiators, sun’s rays, kitchens, household appliances such as televisions, refrigerators, computers, etc.), and vibrations, at about 1.5m from floor level, ensuring normal air flow around the thermostat.

 

Installation

With reference to the figures on the side, open the thermostat by pressing down lightly on the side slot and remove the front panel from the base.

Remove the cover that protects the electrical terminals by sliding it to the side

Secure the base to the wall using the holes provided for various installation needs, being careful to properly pass the cables through the special slot
N.B.: When securing the device to a brick wall, it is recommended to use plugs with max. outer diameter of 5 mm, making sure you do not tighten the screws excessively

Connect the wires to the terminal board as shown in the electrical diagram, and reposition the terminal cover by sliding to the side after inserting it in the special housing

After replacing the front plane open the front panel, unfasten the battery holder cover and insert two 1.5V type LR6 batteries (AA alkaline) in the special compartment, according to the indicated polarity

Electrical connections

  • POTENTIAL-FREE CONSENT: connect the device to be enabled directly to terminals No.1 and No.2
  • LOAD USER SUPPLIED (230VAC) COMMAND: connect the cables to terminals No.1 and No.2 as in the following electrical diagram :

Description of controls and operation

TURNING ON THE DEVICE FOR THE FIRST TIME

After inserting the batteries and powering on the thermostat, the display shows for a few seconds all the available segments and symbols (self-diagnostics), after which the thermostat presets itself for the CLOCK AND WEEKDAY PROGRAMMING.

 

CLOCK AND WEEKDAY PROGRAMMING

This setting sequence can be accessed in the following ways:

  • Automatically the first time the batteries are put in or when replacing discharged batteries
  • Automatically after pressing button “R “ ( Reset )
  • Pressing in sequence button and then button  , keeping hem both pressed for 5 seconds

During this phase the “SET” icon flashes.

1. Set the hour using buttons
2. Press “M” to confirm.

3. Set the minutes using buttons
4. Press “M”to confirm.
5. Set the day of the week using positioning the frame on the number that corresponds, sequentially, to the day of the week (1,2….7).
6. Press “M”to confirm.


At the end of the clock and weekday setting sequence (or in any event after 10 minutes have elapsed from its activation), the device automatically turns on the system with the previous settings.

Only when the device is turned on for the first time, in other words when the internal memory has never been programmed by the user, the device starts to operate with the following factory settings:

  • Operation = WINTER
  • Mode = AUTO
  • WINTER Programme = temperature NORMAL (T1) 7/7day-24/24h
  • SUMMER Programme = temperature NORMAL (T1) 7/7day-24/24h
  • Temperature NORMAL (T1) = 20°C (WINTER)
    = 25°C (SUMMER)
  • Temperature REDUCED (T2) = 16°C (WINTER)
    = 30°C (SUMMER)If the clock and weekday programming is not completed within 10 minutes from its activation the first time the device is turned on, the following factory settings will apply:
  • Time = 00:00
  • Day = 1

SETTING THE SUMMER / WINTER OPERATION

The thermostat can be set for “summer” or “winter” operation, depending on whether an air conditioner or a boiler is connected to it. To switch from SUMMER and WINTER mode, press button for at least 5 seconds. The display will show on the right the special icon according to the active selection () for the WINTER mode and for the SUMMER mode).

SETTING THE OPERATING MODE

Button “ “ can be used to select one of the four operating modes offered by the thermostat. Each time you press the button, the operating mode will change as shown in the image below:

Note: The AUTOMATIC and manual operating modes in OVERRIDE T1 or T2 can be combined with both  SUMMER and WINTER modes, while the FROST-PROTECTION mode automatically sets the thermostat to WINTER operation. 

Automatic mode

In AUTOMATIC mode, the thermostat sets the ambient temperature at the T1 or T2 values, according to the time programming for each day of the week.
To confirm the active automatic mode, the display shows the AUTO icon, the values set for T1 and T2, and the time programme for the current day.
(Example of display in winter operation)

Manual mode T1 OVERRIDE

In this MANUAL mode, the thermostat sets the ambient temperature at the NORMAL (T1) value, regardless of the time programming set and the position of the micro switches.
To confirm that the NORMAL OVERRIDE is active, the display shows icon MAN and the value set for T1.
(Example of display in winter operation)

Manual mode T2 OVERRIDE

In this MANUAL mode, the thermostat sets the ambient temperature at the REDUCED (T2) value, regardless of the time programming set and the position of the micro switches.
To confirm that the REDUCED OVERRIDE is active, the display shows icon MAN and the value set for T2.
(Example of display in winter operation)

FROST-PROTECTION Mode

In this mode, the thermostat sets the ambient temperature at a value of 6°C, excluding any other temperature control and the possibility to change the SUMMER/WINTER operation setting.
To confirm that the FROST-PROTECTION is active, the display shows icon FROST-PROTECTION, and  the relevant set temperature value (6°C)

 

SETTING THE PROGRAMMES

Two different clock operation programmes can be set: one for the WINTER mode and one for the SUMMER mode.
Each programme allows the setting of room temperature adjustment periods at NORMAL (T1) or REDUCED (T2) values, independently for each day of the week.
Access to the setting (or display/check) of the programme, either in WINTER or in SUMMER mode, is not allowed when the device is operating in the MANUAL OVERRIDE mode (at temperature T1 or T2) or in the FROST-PROTECTION mode.

The device is equipped with 24 lever micro-switches, corresponding to each hour of the day, which can be used to set the time programme.
During the programming phase, the micro-switches must be positioned with the levers facing upward (position T1) for the hours of the day in which you want to set the NORMAL temperature and downward (position T2) for those hours in which you want to set the REDUCED temperature. Example: micro-switch number 7 facing upward sets the NORMAL (T1) temperature from 7:00 am until 7:59 am.

The micro-switch position is set and memorized exclusively during the PROGRAMME SETTING procedure, consequently repositioning the micro-switches has no effect in any other operating condition.

After making sure that the device is in AUTOMATIC mode and that the desired operating mode is selected, ( WINTER or SUMMER ), proceed as follows to set the programme:

1. Press in sequence button and afterwards button and keep both buttons pressed for 5 seconds.
The number “1” (identifying the first day of the week) will flash on the display along, until the end of the setting operation, with the “SET” icon.
2. To select a different day, press button “M ” repeatedly.

3. Position all micro-switches on T1 or T2 for the selected day, as described above.
4. Press  button  to confirm and display the changes made. If, on the other hand, you wish to move on to the following day without saving the changes, press “M ”.


5. Proceed in the same way for all the other days of the week .
6. Pressing button “M ” on the day identified with number “7” ends the PROGRAMME SETTING phase and brings the device back to the AUTOMATIC mode with the new settings


Note: In case no setting is carried out for about two minutes during the operating programme setting phase, the device automatically goes back to operating with the previous settings.
At the first power on, both weekly operating programmes (WINTER and SUMMER) are set for operation with temperature NORMAL (T1) for all the hours of each day . 

SETTING THE NORMAL TEMPERATURE (T1)

You can always set NORMAL (T1) temperature, even with the front panel closed, by pressing buttons  
You can change the temperature between 5°C and 35°C in 0.1°C increments in both winter and summer operation.
During the setting, the icon flashes until the new value is stored.

SETTING THE REDUCED TEMPERATURE (T2)

The REDUCED (T2) temperature is set by pressing button “T2 “ in sequence.
Its value can be selected from 6°C, 14°C, 16°C or 18°C in case of winter operation, or 38°C, 30°C, 28°C or 26°C in case of summer operation.
During the setting, the icon flashes until the new value is stored.

REPLACING THE BATTERIES

When the symbol (batteries discharged) flashes on the display, the batteries must be replaced as soon as possible.
In this situation, the clock thermostat will keep on working properly for a short period, after which the system will be turned off permanently using the energy left over in the batteries. From this moment on, the display will show both the writing  and the fixed symbol .

CAUTION!!

  • Permanent system deactivation is not guaranteed in case of anomalous discharging of the batteries.
  • Rechargeable batteries cannot be used for this device.
  • Use only quality alkaline batteries.

To replace the batteries, lift up the front panel and unfasten the battery holder cover, then take out the discharged batteries and put in 2 new 1.5V type LR6 batteries (AA alkaline) in the special housing, according to the indicated polarity. Once the batteries have been replaced, put the cover back on the battery holder compartment and close the front panel.
After putting in the batteries, the display shows all the available segments and symbols for a few seconds (self-diagnostics), after which the device presets itself for CLOCK AND WEEKDAY PROGRAMMING.

Once the CLOCK AND WEEKDAY setting sequence is completed (or in any event after 10 minutes have elapsed from its start), the clock thermostat presets itself to turn on the system, according to the time programme and the previously entered settings.

Note: Under normal conditions of use, batteries allow the thermostat to work for more than 1 year. However, it is recommended to replace the batteries when the heating system is turned on for the season, even though the symbol  (batteries discharge) does not appear on the display, and to remove them in case of long periods of inactivity .
To protect the environment, spent batteries must be thrown away in special containers so that they can be properly disposed of.

 

RESETTING THE DEVICE

Press button “R “ (Reset) to reset the device without affecting any previously set operating parameters, except the clock and the day of the week, which are zeroed out.
The positive outcome of the resetting operation is confirmed by the simultaneous display, lasting a few seconds, of all the symbols (self-diagnostics), followed by the request to set the CLOCK AND WEEKDAY.
Once the CLOCK AND WEEKDAY setting sequence is completed (or in any event after 10 minutes have elapsed from its start), the clock thermostat presets itself to turn on the system, according to the previous settings.

CLEANING

To clean the thermostat, it is recommended to use a soft cotton cloth, slightly dampened. Do not use Kleenexes to clean the display.
Avoid using detergents, solvents, abrasive products, alcohol, ammonia or generic products that can damage the thermostat case.
