Introduction
Chronothermostat CH150TS/151TS/152TS is
suitable to measure the ambient temperature
and to control the heating and air conditioning
system to which it is connected. The operat-
ing mode can be chosen between the preset
ones or can be customized according to user’s
needs.
The wide display shows the temperature pro-
file — i.e.: the relationship between the time ta-
ble and the temperature to be kept —, as well
as the measured temperature, relative humid-
ity, calculated perceived temperature, time and
day of the week.
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.
The chronothermostat is available in the fol-
lowing version:
• CH150TS Chronothermostat with 5 A relay
The following external interfaces are available
for CH150TS chronothermostat:
• Separate temperature probe;
• Telephone activator with GSM modem, for re-
mote management via SMS messages.
The telephone activator enables the following:
• remote communication with the chronother-
mostat to know the ambient temperature or
the status of the heating or air conditioning
system;
• remote management of the chronothermostat
operating modes.
The chronothermostat comes in three colours:
white, silver (CH151TS series) and anthracite
black (CH152TS series).
Unless otherwise specified, the instruc-
tions contained in this manual apply to every
chronothermostat model.

Operating modes
The CH150/151/152 chronothermostat fea-
tures four different operating modes: Manual,
Automatic, Holiday and Jolly (in addition to the
OFF function).
“Manual” operating mode
With the Manual operating mode, the chrono-
thermostat adjusts the operation of the heating
or cooling system in order to always keep the
same temperature. To select “Manual”, press
MAN.

8
The temperature level can be modified during
operation by means of the lower rotary selec-
tor located on the right side of the chronother-
mostat. The temperature can be changed from
2°C to 40 °C by 0.1°C increments.
“Automatic” operating mode
With the “Automatic” operating mode, the
chronothermostat adjusts the operation of the
heating or cooling system by following the pro-
files 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 ro-
tary selectors located on the right side of the
chronothermostat.

9
Temperature T3 cannot be lower than tem-
perature T2 or higher than 40 °C.
During Summer operation, temperature
T3 features an upper limit of 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 tem-
perature T3 or lower than temperature T1.
Temperature T1 cannot be higher than tem-
perature T2 or lower than 2 °C.
If no customization has been made, the au-
tomatic operating mode will function with the
stored temperature profiles, i.e. the preset
ones (refer to «Preset programs»). To custom-
ize the profiles, refer to «Chronothermostat
programming».

10
To modify the temperature levels, refer to
the description of the “Automatic” operating
mode.
When the preset programs are used (refer to
«Preset programs»), the “Holiday” mode will
follow the profile envisaged for Saturdays and
Sundays. To create a customized “Holiday”
program, refer to «Chronothermostat program-
ming».
“Jolly” operating mode
With the “Jolly” operating mode, the CH150
chronothermostat interrupts the current oper-
ating mode and adjusts the operation of the
heating or cooling system to keep the “Jolly”
temperature during the entire time set (1 hour
to 99 days and 23 hours, by 1 hour incre-
ments). After this time – which is displayed like
a countdown – has elapsed, the previous oper-
ation of the chronothermostat will be resumed.
To select “Jolly”, press JOLLY.
The “Jolly” temperature value and the operat-
ing mode duration can be modified by means
of the rotary selectors located on the right side
of the chronothermostat.
“Holiday” operating mode
With the “Holiday” operating mode, the CH150
chronothermostat CH150 adjusts the opera-
tion of the heating or cooling system by fol-
lowing one single temperature profile, which
is valid for all days. To select “Holiday”, press
HOLIDAY.

11
Use the lower rotary selector to modify the
temperature level.
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 week-
ends or winter vacation, while being sure that
a comfortable temperature will exist when the
house is inhabited again);
• extend the night heating or cooling beyond
the usual time, i.e. when you stay up in the
company of your guests.

12
“OFF” function
The “OFF” function can be activated by press-
ing OFF.
Winter operation
The system will be fully turned off and the
“OFF” message will appear on the display,
without any temperature profile.
The chronothermostat adjusts the operation
of the heating system to keep the “Antifreeze”
temperature, in order to reduce the energy
consumption and, at the same time, avoid any
damage caused by extremely low tempera-
tures.
The “Antifreeze” temperature can be modified
from 2°C to 7°C (by 0.1°C increments), by us-
ing the lower rotary selector. If a temperature
of less than 2°C is set, the system will be fully
turned off and the antifreeze protection will be
lost.
