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.

“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.
