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.

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.

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
weekends 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 programmable thermostat 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 temperatures.
The “Antifreeze” temperature can be modified
from 2°C to 7°C (by 0.1°C increments), by
using 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.

Important: Standard battery life is approx. 1
year. You are recommended to replace batteries
at the beginning of system operating season to
prevent batteries from running down when you
are away from home, e.g. during Christmas
holidays.
The batteries shall be properly disposed of in
special containers.
Replacing the batteries
When the battery charge starts to lower,
symbol on the display will start flashing.
If the “bAtt” parameter is set to “On” or to
“Off” (see paragraph <<configuring the
programmable thermostat>>) and batteries are
not replaced within 15 days, the programmable
thermostat will turn off automatically and the
display will show the message “OFF” or “On”
instead of the temperature value.
Settings and data are however stored in the
non-volatile memory.
To remove the programmable thermostat from
the base proceed as follows:
• remove the jack plug from the telephone
activator, if any;
• pull the left and right sides of the
programmable thermostat, without applying
force to selectors.
If after replacing the batteries, the display
only shows the message OFF or ON, press
the icon key with ENTER after refitting the
programmable thermostat on the base.
With the “bAtt” parameter off (see paragraph
<<configuring the programmable thermostat>>),
and symbol flashing, batteries shall be
changed as soon as possible to prevent that
battery charge becomes insufficient for regular
programmable thermostat operation.
