Introduction
Chronothermostat CRONOTC...B is suitable to measure the ambient temperature
and to control the heating and air conditioning system to which it is connected.
The operating mode can be chosen between the preset ones or can be customized
according to user’s needs.
The wide display shows the temperature profile - i.e.: the relationship between the time
table and the temperature to be kept -, as well as the measured temperature, relative
humidity, calculated perceived temperature, time and day of the week.
NOTE Temperature perceived is calculated according to the following formula:
Where “H” is the perceived temperature, “T” is the effective air temperature.
Values in brackets represent the empirical calculation of the air steam partial
pressure (according to the relative humidity).
The chronothermostat is battery powered. Both settings and data are stored in a non-
volatile memory capable of retaining them even when batteries are down.
It it possible to connect the chronothermostat to an external floor temperature
probe (AVE p.n 53GA91-T).
Chronothermostat is available in the following colours:
• "Domus RAL 9010" white (p.n. CRONOTC1B)
• "Life" black (p.n. CRONOTC2B)
• "Allumia" grey (p.n. CRONOTC3B)

Operating modes
The CRONOTC...B chronothermostat features four different operating modes:
Manual, Automatic, Holiday and Jolly (in addition to the OFF function).
“Manual” operating mode
With the Manual operating mode, the chronothermostat adjusts the operation of
the heating or cooling system in order to always keep the same temperature. To
select “Manual”, press MAN.
The temperature level can be modified during operation by means of the
lower using either one of the three rotary switches on the right side of the
chronothermostat.The temperature can be changed from 2°C to 40 °C by 0.1°C
increments.
Winter Summer

“Automatic” operating mode
With the “Automatic” operating mode, the chronothermostat adjusts the
operation of the heating or cooling system by following the profiles defined
for the various days of the week. To select “Automatic”, press AUTO.
The three temperature levels used can be modified during operation by means
of the rotary selectors located on the right side of the chronothermostat.
Temperature T3 cannot be lower than temperature T2 or higher than 40 °C.
In Summer operation mode, the upper limit of temperature T3 is 30°C. When
this value is exceeded, T3 will take the OFF value, which will involve switching
the system off.
Temperature T2 cannot be higher than temperature T3 or lower than
temperature T1.
Temperature T1 cannot be higher than temperature T2 or lower than 2 °C.
If no customization has been made, the automatic operating mode will function
with the stored temperature profiles, i.e. the preset ones (refer to «Preset
programs» pag. 35). To customize the profiles, refer to «Chronothermostat
programming» pag. 35.

ENGLISH
“Holiday” operating mode
With the “Holiday” operating mode, the chronothermostat adjusts the operation
of the heating or cooling system by following one single temperature profile,
which is valid for all days.
To select “Holiday”, press HOLIDAY.
To modify the temperature levels, refer to the description of the “Automatic”
operating mode (pag. 31).
When the preset programs are used (refer to «Preset programs» pag. 35), the
“Holiday” mode will follow the profile set for Saturdays and Sundays. To create a
customized “Holiday” program, refer to «Chronothermostat programming» (pag.
35).
“Jolly” operating mode
With the “Jolly” operating mode, the chronothermostat interrupts the current
operating mode and adjusts the operation of the heating or cooling system to
keep the “Jolly” temperature during the entire time set (from 1 hour to 99 days
and 23 hours, by 1 hour increments). After this time – which is displayed like a
countdown – has elapsed, the previous operation of the chronothermostat will
be resumed. To select “Jolly”, press JOLLY.
The “Jolly” temperature value and the operating mode duration can be modified
by means of the rotary selectors located on the right side of the chronothermostat.
Use the lower rotary selector to modify the temperature level.

ENGLISH

The temperature can be modified from 2°C to 40 °C, by 0.1 °C increments.
To set the “Jolly” operating mode duration, i.e. hours («h»), use the central rotary
selector. The hours can range from 0 to 23.
To set the “Jolly” operating mode duration, i.e. days («d»), use the upper rotary
selector.
The days can range from 0 to 99.
You can interrupt the “Jolly” mode at any time, by selecting any other operating
mode.
The “Jolly” operating mode can be used, for instance, to:
• saveenergybyloweringthetemperaturewhenthehouseisnotinhabitedatthe
