6.3 - PROGRAMMA HOLIDAY P 06

The weekly-setting wall mounting chronothermostat suitable for heating and/or cooling systems, is equipped with a big, clear display (some models have the backlight function) so as to monitor all functions in real time.

Its principal feature is the ease with which it can be programmed, in fact, despite the number of functions it has, it is very simple to use. Various programmes are already set in its permanent memory, at 3 and 4 temperature levels, designed to provide maximum comfort. However, only a few seconds are needed to set the preferred temperatures to be applied throughout the day (even every 30 minutes!) and also for each day of the week. A standard function of the chronothermostat consists of the automatic adjustment of the temperature in the ON/OFF differential mode, so as to adjust itself to the thermal inertia of your particular system - the temperature can be set between 0.2°C and 2°C. Otherwise, you can choose the function in proportion with the cycles, which can be set to last 7-10-15-20 minutes, thus reducing the operating time of the boiler, which depends upon the difference between the set temperature and that of the room (the smaller the difference in temperature, the less time the boiler functions).

Moreover, the chronothermostat can automatically anticipate ignition (intelligent function), for the room to reach the desired temperature at a particular time. The set temperature scale is in degrees centigrade (Celsius) and you can calibrate the measurement of temperature by setting a correction value (from -1.9 to +1.9 °C). When switched to degrees Fahrenheit, all temperature settings are updated according to the new temperature scale.

Particular attention has been given to the energy saving factor: the Holiday function, the interruption function for domestic cleaning, the option to block the set temperatures, the anti-freeze temperature can be set between 4 and 12 °C, telephonic control (optional telephone programmer). These prevent energy from being wasted, which leads to economic savings (refer to the following pages for the description of these and other functions).

6.4 - DISPLAYING CONSUMPTION CALCULATED CHECKING THE HOURS OF OPERATION OF THE APPLIANCE

The chronothermostat calculates and memorizes the hours of operation of the burner (and/or air conditioner) both during the 24 hours of the previous day and from the start of the season (total hours operation). This information is useful in monitoring (for indicative purposes) the energy consumption of the system. Total consumption for the system in litres (fuel oil) or cubic metres (natural gas) can be computed simply by multiplying the hourly consumption value (indicated on the data plates of the burner) by the hours operation.

• To display the operating timed during the last24 hours:
Briefly press (Fig.29) and the requested number of hours of operation will appear on the display.
- To display the total hours operating from the beginning of the season: press and hold C for at least 4 seconds (fig.30), and the total hours operation will appear.
- To reset the total hours operation from the beginning of theseason: press and hold for at least 8 seconds (until the temperature scale setting ends within 24 hours), then press OK simultaneously; 0000 will appear on the display for a few seconds (total hours device operation counter reset), release C and OK

Following the reset, the chronothermostat begins anew count of the total hours operation.

6.5 - EXCLUSION OF THE CHRONOTHERMOSTAT (OFF)

Press and hold button √/○ until OFF appears in the display, to indicate

that thechronothermostat isdeactivated (fig.31).

To reactivate the program interrupted before the end of the 3 hours, press button the missing digits will reappear.

Warning: if the antifreeze temperature is deselected permanently (see heading 7.5), or in "summer" operation, the controlled appliance will keep disabled for three hours.

6.7 - INDICATION OF SYSTEM TROUBLE

In Winter:

if, during normal operation ONlinking), the chronothermostat does not sense a significant rise in temperature within 2 hours, the display will indicate that the heating system isnotworking HQF5.

In Summer

if, during normal operation ONlinking), the chronothermostat does not sense a significant rise in temperature within 2 hours, the display will indicate that the heating system is not working OFF.

The indication will disappear automatically as soon as a significant rise (winter) or drop (summer) nature has registered.

Note: in both cases, the relay remains ON (device is enabled)

7 - PROGRAMMABLE FUNCTIONS FOR USE WITH DIFFERENT APPLIANCES

7.1 - TEMPERATURE DIFFERENTIAL (ON/OFF)

The chronothermostat operates (factory set) in differential mode ON-OFF with a differential value factory-set to 6 °C

The differential value must be set according to the system's thermal inertia; a low value is recommended for systems with radiators (e.g. in cast iron) and a high value for systems with fan coils.

The differential value may be displayed and changed as follows:

• Ensure that the DIFFERENTIAL ON/OFF mode is selected as shown in paragraph. 7.3.
• Press and hold t1 until the existing differential value blinks on the display, e.g. d0.6c
• Change the value (from 0,2 °C to 2 °C) using the buttons ▲ or ▼ which give increments of 0,1 °C; press OK 3 times once the desired value is reached to return to the set program.

7.2 - PROPORTIONAL OPERATION

As opposed to the differential, the temperature can be adjusted proportionally with adjustable cycles of 7, 10, 15 or 20 minutes. This system maintains the desired temperature more stable by increasing the user's sense of comfort and saving on energy consumption.

The duration of the cycle can be viewed and changed as follows:

• Ensure that the PROPORTIONAL mode is selected as shown in paragraph 7.3.
• Press t1 until the cycle in progress blinks on the display e.g. P 10 (factory set).
• Select the desired cycle by pressing ▲ or ▼ (P 07 = 7 minutes; P 10 = 10 minutes; P 15 = 15 minutes; P 20 = 20 minutes); press OK 3 times to return to the set program.

Note: the setting will not be effected by a reset.
