• Button .
Holding down this button makes it possible to select the operating
mode of the chronothermostat, choosing between "Heating" or
"Air-conditioning". When the symbol
use the button to select the mode.

• Button .
Pressed in sequence, makes it possible to set the values for the
"Antifreeze temperature", of the "Temperature levels T1-T2-
T3", the "Hysteresis", and "Temperature scale".
Set the individual levels using the button
Confirm with the button
- ANTIFREEZE.
Available only in heating, sets a minimum temperature level to
avoid damaging the wires, or to prevent the temperature from
falling below a given safety level.
- TEMPERATURE LEVELS.
Displays and/or modifies the values of the temperature set-points
T1, T2, T3 for both heating and cooling programs.

- 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
flashes,
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 be-
low 19.7 °C, and will switch off when the ambient temperature
reaches 20.3 °C.
- TEMPERATURE SCALE.
Used for setting the units of measurement for temperature, choos-
ing between degrees Celsius and degrees Fahrenheit.
• Button .
Sets the current day of the week and time. In programming, it is
used to set the time in 15-minute increments.
