- TIMED MANUAL.
Used to set the chronothermostat in the
“Manual”
operating mode for a specific period of time (up to 99 hours);
at the end of this time, the device sets the operating mode that had previously been selected�
- AUTOMATIC.
Used to set a time program for temperature control in the chronothermostat�
• Button
.
Keeping the button held down enables selecting the chronothermostat operating mode, choosing between
“Heating”
and
“Air-Conditioning”
�
• Button
.
Pressed in sequence, it enables setting the values of the
“Antifreeze Temperature”,
of the
“Temperature Levels
T1-T2-T3”,
of the
“Temperature Differential”,
and of the
“Temperature Scale”
�
- TEMPERATURE LEVELS.
Used to display and/or modify the value of temperature levels T1-T2-T3 for both the heating and air-conditioning
programs�
- TEMPERATURE DIFFERENTIAL.
Used to set the value of the temperature differential� The
temperature differential
is the difference between the set
temperature and the actual temperature of switching the system on or off� Adjusting the temperature differential to
the type of system avoids continual switching on and off; high inertia systems (for example systems with cast-iron
radiators) need a low temperature differential, while low inertia systems (for example fan heaters) need a higher value�
Example.
If the ambient temperature is set to 20°C and the temperature differential is set to 0�3°C, the system will come on
when the ambient temperature falls to 19�7°C and will go off when it reaches 20�3°C�
- TEMPERATURE SCALE.
Used to set the unit of measurement of the temperature, choosing from between degrees Celsius and degrees
Fahrenheit�
• Button
�
Used to set the current time and day of the week� When programming it is used to select the time in steps of 15 minutes�
• Button
�
Kept pressed down, all the parameters set on the chronothermostat go into the conditions of first switching
on (resetting the clock, deleting the user programs, return to the default values for the 3 levels of temperature)�
This command does not involve the parameters relating to the GSM part (telephone numbers, parameters of the
digital input, etc�) that are restored to the conditions of first switching on via a specific menu�
