1.DESCRIPTION.

Electronic timer-thermostat for ON/OFF ambient temperature control (heating and air-conditioning), daily/weekly programming, class I temperature control device (contribution 1% ), change-over relay output 6(2) A 230 V~, power supply 120-230 V~ 50/60 Hz - 2 modules.

2. SCOPE.

The chronothermostat is suitable for ambient temperature control by regulating the supply circuit of the burner or heat pump (heating), or the supply circuit of the air conditioner (air conditioning), to maintain ideal temperature conditions seven days a week. Its multiple functions enable the user to choose between the fixed programs stored in memory, or to create personalised programs.

The roomy display shows the ambient temperature, the day of the week, the time, the status of the heating or air conditioning system and the daily temperature profile for the currently active program. There is a simple and intuitive procedure for programming all the parameters, assisted by interactive menus (all instructions shown on the display), using the 4 buttons on the front of the chronothermostat.

3. INSTALLATION.

The thermostat must be installed in flush or surface mounting boxes with frames and plates at a height of 1,5m above floor level, in an appropriate position for measuring the ambient temperature; do not position the instrument inside niches, behind doors and curtains, close to heat sources or in areas influenced by outside weather conditions. In particular, it should not be installed on perimeter walls or near electrical devices which generate heat (e.g. dimmers or lamps).

The thermostat is designed for use in dry, dust-free areas with an ambient temperature between 0^ and +40^ .

5.2 - Phone dialer control.

It is possible to control the timer-thermostat remotely with a phone dialer.

By closing the contact connecting the terminal to the line L, the timer-thermostat is forced onto manual operation and the four keys

A, B, C and D are locked (if any key is pressed the display will show Man blinking for approximately 3 s.)

On opening the contact the timer-thermostat goes onto:

• Antifreeze mode if heating is on;

• OFF if air-conditioning is on.

In this phase the keys of the timer-thermostat are not locked and it is possible to operate the device.

6. USING THE ELECTRONIC TIME-PROGRAMMABLE THERMOSTAT.

To program the electronic thermostat, from the starting screen of the display, press any one of the four front buttons.

The following icons appear:

• "Esc" (button A): cancels the selection.
• "▼" (button B): displays the value of the currently active temperature set-point (Ts) and, when the button is next pressed, allows this value to be reduced by the desired amount; pressing "Set" (button D) causes this new value to remain active until the next programmed temperature set-point change, after which the program stored in memory is resumed.
• “▲” (button C): displays the value of the currently active temperature set-point (Ts) and, when the button is next pressed, allows this value to be increased by the desired amount; pressing “Set” (button D) causes this new value to remain active until the next programmed temperature set-point change, after which the program stored in memory is resumed.
• "Menu" (button D): used for accessing the "Operation" menu.
• Press "▼" (button B): the "Settings" and "Programming" menu items appear; "▲" (button C) scrolls up in the menu, "ok" (button D) selects the desired menu, and "Esc" (button A) returns to the starting screen.

6.1 OPERATION.

Selects the operating mode of the programmable thermostat, choosing between "Auto/Manual", "Switching off", "Heating/Air Con.", "Antifreeze".

• Confirm "ok" (button D) = scroll menu using "▼" (button B) and "▲" (button C), select setting using "Set" (button D) for "Auto/Manual", "Switching off", "Heating/Air Con.", "Antifreeze".

- AUTO/MANUAL.

Configures the programmable thermostat for either automatic or manual operation.

In "Automatic" mode, the temperature is regulated by the currently active programme stored in memory (see "Select Prog.", page 22).

In "Manual"mode, the switch-on and switch-off of the heating or cooling system can be controlled manually:

• "▼" (button B): displays the value of the currently active temperature set-point (Ts) and, when the button is next pressed, allows this value to be reduced as required.
• "▲" (button C): displays the value of the currently active temperature set-point (Ts) and, when the button is next pressed, allows this value to be increased as desired.

VIMAR

• Press "Set" (button D) to confirm the selection or "Esc" (button A) to revert to the preceding setting.

- SWITCHING OFF.

HEATING/AIR CON.

Allows the system to be switched off immediately, or after a pre-established time delay.

Configures the programmable thermostat for either heating or cooling.

ANTIFREEZE.

Defines a minimum temperature threshold to prevent the pipes from freezing up or to ensure the temperature does not drop below an established safety level.

6.2 SETTINGS.

Used for setting "Clock", "Hysteresis", "Temp. Scale.", "Language", "Display", "Password" and "Calibration".

• Confirm "ok" (button D) = scroll menu using "▼" (button B) and "▲" (button C), select setting using "ok" (button D).

CLOCK.

Used for setting the current date and time.

HYSTERESIS.

Adjusts the value of the temperature hysteresis parameter. Hysteresis is the amount by which the ambient temperature can deviate from the set-point before the system is switched on and off. By adapting the hysteresis parameter to the type of system, it is possible to prevent repeated switch-on and switch-off around the set-point value; systems with high inertia (for example with cast iron radiators) require a low hysteresis value, whereas systems with low inertia (for example fan-convectors) require a higher value.

Example.

If the ambient temperature is set to 20^ and the temperature differential is set to 0.3^ , the system will come on when the ambient temperature falls to 19.9^ and will go off when it reaches 20.3^ .

- TEMP. SCALE.

Used for setting the units of measurement for temperature, choosing between degrees Celsius and degrees Fahrenheit.

LANGUAGE.

Used for setting the language in which the instructions are displayed, choosing between Italiano, English, Frangais, Espanol and Deutsch.

- DISPLAY.

Allows the user to adjust the display contrast.

VIMAR

- PASSWORD.

Allows the user to configure, change or disable a 3-digit PIN password to prevent unauthorized access to the thermostat functions, settings and programs.

Attention!

Remember to make a note of the PIN number in the special space provided on pg. 14.

CALIBRATION.

Used for compensating for any differences between the actual ambient temperature and the value shown on the display, because certain installation conditions may alter the thermostat's reading of the ambient temperature.

6.3 PROGRAMMING.

Used for selecting the program to be executed "Select Prog.", for editing the user programs "Modify Program" and for displaying and/or changing the temperature set-points used in the various programmes "Temp. Levels".
