Introduction
Programmable thermostat CH150 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.
The programmable thermostat is battery
powered. Both settings and data are stored
in a non-volatile memory capable of retaining
them even when batteries are down.
The programmable thermostat is available in
the following version:
• CH150 Programmable thermostat with 5A
relay.
• CH150-16 Programmable thermostat with
16A relay
For programmable thermostats CH150 and
CH150-16 the following external interfaces are
available:
• Separate temperature probe;
• Telephone activator with GSM modem, for
remote management via SMS messages.
The telephone activator enables the following:
• remote communication with the
programmable thermostat to know the
ambient temperature or the status of the
heating or air conditioning system;
• remote management of the programmable
thermostat operating modes.
The programmable thermostat comes in three
colours:
white, silver (CH151 series) and anthracite
black (CH152 series).
Unless otherwise specified, the instructions
contained in this manual apply to every
programmable thermostat model.

User manual
To operate the programmable thermostat after
it has been installed, proceed as follows:
1. Set the date and time.
2. Select the Summer/Winter operation.
3. Select the operating mode.
Setting the date and time
To set the current time and date, proceed as
follows:
1. Enter the programming menu main page.
The operating mode currently used will be
interrupted temporarily. Choose the time
setting function.
2. Modify the hour setting by means of the ▲
and ▼buttons, then go to the minute setting
by means of the ►button.
3. Modify the minute setting by means of the
▲and ▼buttons, then go to the day setting
by means of the ►button.
4.Modify the day setting by means of the ▲
button, then press ENTER to go back to the
main page of the programming menu.

5. Press ENTER again to exit the program-
ming menu. The programmable thermostat
operating mode previously interrupted will be
resumed.
Summer/Winter selection
To shift from the Summer
operation (heating system) to
the Summer operation (cooling
system), and vice versa, keep the
Summer/Winter button depressed
for at least 4 seconds. The
selected operation will be shown
on the display by means of the
“Winter” or “Summer” icons.

Operating modes
The CH150 programmable thermostat 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
programmable 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 selector
located on the right side of the programmable
thermostat. 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
programmable thermostat 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
programmable thermostat.

9
Temperature T3 cannot be lower than
temperature 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
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»).
To customize the profiles, refer to
«Programmable thermostat 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 «Programmable thermostat
programming».
“Jolly” operating mode
With the “Jolly” operating mode, the CH150
programmable thermostat 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 (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 programmable
thermostat 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 programmable thermostat.
“Holiday” operating mode
With the “Holiday” operating mode, the CH150
programmable thermostat CH150 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.
