OPERATIONS:
Act on the master switch on the electric
panel to cut power to the electrical system;
Connect the two wires of the boiler to
terminals 1-2 of chronothermostat;
Connect the two power cables L-N;

OPERATING PROGRAMS
The CH193 chronothermostat has different operating modes, called programs:
“AUTO” WEEKLY PROGRAM:
one of the four programmable temperatures can
be associated to each half hour for each day of
the week. This is the program displayed when the
chronothermostat is switched on and is generally the
one most used.
“HOLIDAY” DAILY PROGRAM:
Like in the AUTO program, you may select one of the
4 programmable temperatures for each half hour, but
the identical sequence will be repeated every day.

SETTING TIME AND DATE
After the device switches on, press the key
PROG briefly: the text “Setup” is displayed;
now press to enter the “Hours” page. Set
the hour by pressing and . Then press
to go to the “Minutes” setting.
Again press to select, in order, the Year,
Month and Day.
Pressing again allows you to choose
whether to disable automatic change of

“JOLLY” TEMPORARY PROGRAM:
you may choose to hold a certain temperature for a
certain number of hours, after which it will go back to
the previously active program.
“MAN” MANUAL PROGRAM:
the chronothermostat maintains a fixed temperature,
for an unlimited amount of time until another program
is selected.
SYSTEM OFF OR WITH ANTIFREEZE PROGRAM “OFF/ANTIFREEZE”:
the system remains off or else maintains a very low
temperature (from 2 to 7°C) to prevent the fluid in the
heating system from freezing.

SETTABLE TEMPERATURES
Four different temperatures can be set and one can be selected for each half hour
of the day in the AUTO and HOLIDAY programs. Three of these temperatures (T1,
T2 and T3) can have values from 2° to 40°C, while the fourth, T antifreeze (TA), can
range from 2° to 7°C, or be set at “OFF” (system off). The manual program has
its specific temperature (TMan), like the JOLLY program (Tj), which are set in the
respective screens and can range from 2° to 40°C.
The ANTIFREEZE/OFF program, on the other hand, follows the temperature TA
which, as we have said, can range from 2° to 7°C; or else, it can be set at “OFF”,
switching the plant completely off.

PROGRAMMING AND DAILY “HOLIDAY”
PROGRAMMING
Keep the key
PROG pressed until the text
“Config” is displayed. This menu allows you to
program the weekly profiles (AUTO program) and
daily profiles (HOLIDAY program) and to set the
advanced functions (see the following paragraphs for their description).
PLEASE NOTE: if the text “Setup” appears instead of “Config”, you did not press
the key long enough and you must press
ENTER to go back to the normal operating
condition and try again.
When you enter the “Config” menu, a page appears which allows you to choose the
desired temperature (T1/T2/T3/Ta) for each half hour of the indicated day (from 1 to
7 indicating the days from Monday to Sunday).
PLEASE NOTE: T1/T2/T3/Ta are displayed on the right of the screen with the

“JOLLY” PROGRAM SETTING
In all programs, except MAN, pressing the key JOLLY selects the temporary
program: this program allows you to define the desired temperature and its
duration in hours (up to a maximum of 240, so to say 10 days).
For example, you may want to keep a lower temperature during the entire weekend
when no one is home.
When you enter this program, you may modify the duration, which initially is one
hour, and increase the number of hours by pressing , or decrease them by
pressing .
Pressing TEMP allows you to view and modify temperature Tj, again using the keys
and .
Pressing sends you back to view the duration of the JOLLY program.
When this time elapses, you go back to the initial program.
“OFF/ANTIFREEZE” PROGRAM SETTING
Pressing OFF from any program switches the chronothermostat to the off/
antifreeze status. The antifreeze temperature (Ta) can be programmed by pressing
TEMP , from OFF (boiler always off) to an interval between 2.0 and 7.0°C, using the
arrow keys and .
Go back to the OFF status by pressing .
Pressing OFF again sends you back to the previous operating status.
ALTERNATIVE DISPLAYS
Other information can be viewed in the AUTO and HOLIDAY programs in place of the
temperature profile, by pressing the key DISP several times.
The first time it is pressed the programmed temperature for the current half
hour appears, the second time it displays the date, the third time it displays the
temperature of the external probe and the fourth time it goes back to the initial
temperature profile.

AVAILABLE PROGRAMS
CH193 has several operating modes (programs):
“AUTO” weekly program
“HOLIDAY” daily program
“JOLLY” temporary program
“MAN” manual program
system off or with antifreeze “OFF”program
“AUTO” WEEKLY PROGRAM
4 temperature levels can be used in the AUTO operating mode (Ta, T1, T2, T3),
according to a programming with 30 minute steps, 24 hours a day, 7 days a week.
The days are numbered from 1 to 7 and correspond to the seven days of the week,
starting from Monday.
To simplify programming, you may set the first day and copy it on the following days.
The default for days 1 – 5 (Monday to Friday) is:
00:00 – 06:30 T1
06:30 – 09:00 T2
09:00 – 11:30 T1

14:00 – 17:00 T1
17:00 – 22:30 T3
22:30 – 24:00 T1
while the default for days 6 and 7 (Saturday and Sunday) is:
00:00 – 08:00 T1
08:00 – 11:30 T2

JOLLY
The JOLLY mode allows you to set a
programmable temperature (Tj) for a
programmable number of hours (from 1 to
240). It is used when you wish to introduce
a temporary variation to programming
without changing the parameters, for
example to maintain a high temperature
for longer when spending an evening with
friends or to keep it low when no one is home the weekend.
If you enter JOLLY mode using the specific function key, when time is up it goes
back automatically to programming in progress.

MANUAL
MAN mode allows you to set a fixed
temperature manually (Tman), ranging
from +2.0 to +40.0 degrees, without
expiring and without needing to modify the
weekly or daily program.
For example it can be used to keep the
house at a different temperature than that
of the daily program when no one is home, or to switch on the system remotely,
bringing it to a constant temperature.

OFF mode is used when you want to switch the system off.
It uses the temperature TA (antifreeze) as a reference, to guarantee protection of
the system at low temperatures.
TA is normally set at +5 degrees, but it can also be set at OFF, to switch the boiler
completely off. Weekly or daily programs remain unchanged.
settable TEMPERATURES
The system can use 4 different temperature levels, three for normal use and one,
called “antifreeze”, to be used when you wish to keep the boiler off, but without
risking having the fluid in the system freeze.
Programming of the three T is conditioned by reciprocal values:
T1 cannot be higher than T2,
T2 cannot be higher than T3.
The temperatures are set using the key
TEMP and and .
T1 ranges between +2.0 and +T2 degrees, with variations every tenth of degree
[default 17.0].
T2 ranges between +T1 and +T3 degrees, with variations every tenth of degree
[default 19.0].
T3 ranges between +T2 and +40.0 degrees, with variations every tenth of degree
[default 20.0].
TA (antifreeze) ranges between +2.0 and +7.0 degrees, with variations every tenth of
degree, or a can be OFF, when the boiler remains off [default 5.0].

WASTE DISPOSAL
The symbol of the crossed-out wheeled bin indicates that the products must be
collected and disposed of separately from household waste. The batteries and
integrated accumulators may be disposed of together with the product. They will
be separated at the recycling facilities. A black bar indicates that the product was
placed on the market after August 13th, 2005.
Participating in the separate collection of products and batteries contributes to
the correct disposal of these materials and therefore avoids possible negative
consequences for the environment and human health. For more detailed
information on the collection and recycling programmes available in your country,
contact the local authorities or the sales point where you purchased the product.
