Introduction
The chronothermostat CH150/151/152 measures the ambient temperature and regulates
the heating or conditioning plant to which it is connected. The mode of operation can be
chosen from among those preset, or can be personalised to meet one’s own requirements.
The conveniently sized display shows the temperature profile or pattern — that is, the
relationship between the time of day and the temperature to be maintained — the
temperature measured, the relative humidity, the calculated perceived temperature, the
time of day and the day of the week.
The chronothermostat is powered by bat teries. The settings and data a re stored in a nonvolati le memory that reta ins the m ev en if the batteries are exha us ted.
The chronothermostat is available in two versions that differ only in the current carrying
capacity of the relay contacts:
• CH150 Chronothermostat with 5 A relay.
• CH150-16
Chronothermostat with 16 A relay
For chronothermostats CH150 and CH150-16 the following external interfaces are
available:
• Separat e t emp er at u re prob e;
• Telephone activator for fixed phone line; this allows remote control from a DTMF
(multitone) keyboard;
• Telephone activator with GSM modem, for remote control by SMS message.
Both activators make it possible to:
• Interrogate the chronothermostat remotely to discover the ambient temperature and
the stat us of th e heating or coolin g p lan t ;
• To manage the operation of the chronothermostat remotely.
The various models are available not only in white but also in the colours silver (series
CH151) and anthracite black (ser i es CH152).
Unless otherwise indicated, the instructions contained in this manual apply to all the
models of chr on ot her mostat.

Modes of operation
The chronothermostat CH150/151/152 has 4 different modes of operation — Manual,
Automatic, Holiday and Jolly — and OFF mode.
Manual mode of operation
In the Manual mode of operation, the chronothermostat regulates the operation of the
heating or cooling plant to maintain the same temperature always. To select Manual, press
the key MAN.
The temperature can be
altered during operation
by adjusting the bottom
rotary selector switch on
the right side of the
chronothermostat. The
temperature can be set
within the range from 2°C
to 40 °C, in 0.1 °C steps.
Automatic Mode of Operation
In the Automatic mode of operation, the chronothermostat regulates the operation of the
heating or cooling system following the patterns set for the various days of the week. To
select Automat ic, pre ss the AU TO key.
The three temperature levels used can be modified during operation by means of the rotary
selector switches on the right hand side of the chronothermo stat.
7
Temperature T3 cannot
be less than temperature
T2 or more than 40 °C.
In Summer operation,
temper at ur e T3 has an
upper limit of 30°C. If this
limit is passed , T3 tak es
the value OFF, which
means switching off the
plant.
Temperature T2 cannot
be above temperature T3
or less than temperature
T1.
Temperature T1 cannot
be above temperature T2
or less than 2 °C.
In the absence of any
personalisation, the Automatic mode operates with the preset temperature patterns
memorised (see «Preset programmes »). To personalise the patterns, see «Progra mming
the chronothermostat».
Holiday Mode of Operation
In the Holiday mode of operation, the chronothermostat CH150 regulates the operation of
the heating or cooling system following a single temperature pattern which is the same
each day. To select Holiday mode, press the HOLIDAY key.
