- Press "Set" (button D) to confirm the selection or "Esc" (button
A) to revert to the preceding setting .
• SWITCHING OFF.
Allows the system to be switched off immediately, or after a pre-
established time delay .
• HEATING/AIR CON.
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 .
7.2 SETTINGS.
Used for setting "Clock", "Hysteresis", "Temp. Scale.", "Lan-
guage", "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 . Hys-
teresis is the amount by which the ambient temperature can devi-
ate 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.
With a temperature set-point of 20 °C and a hysteresis of 0 .3 °C,
the system will switch on when the ambient temperature drops
below 19 .7 °C, and will switch off when the ambient temperature
reaches 20 .3 °C .
• TEMP. SCALE.
Used for setting the units of measurement for temperature, choos-
ing between degrees Celsius and degrees Fahrenheit .
• LANGUAGE.
Used for setting the language in which the instructions are dis-
played, choosing between Italiano, English, Français, Español
and Deutsch .
• DISPLAY.
Allows the user to adjust the display contrast .
