Introduction
The CH150RF/151RF/152RF chronothermo-
stat measures the ambient temperature and
controls the heating (conditioning) system
through a radio connection with an actuator�
A humidistat can also be driven� The operat-
ing mode can be either chosen from among
the preset ones or customized to one’s own
needs�
The large display shows the temperature pro-
le – i.e. the relationship between the time ta-
ble and the temperature to be kept – as well as
the measured temperature, relative humidity,
calculated perceived temperature, time and
day of the week�
The chronothermostat is battery powered�
Both the settings and the data are stored in a
non-volatile memory capable of keeping them
even when the batteries are down�
The following external interfaces are available
for the CH150RF chronothermostat:
• Radio actuator
• Separate temperature probe
• Telephone actuator for xed telephone lines,
which makes it possible to perform remote
control through the DTMF keypad (multi-tone)
• Telephone actuator with GSM modem, used
for remote control by means of SMS mes-
sages�
Both telephone actuators allow you to:
• remotely interrogate the chronothermostat, to
be informed about the ambient temperature or
the heating / cooling system status;
• remotely manage the chronothermostat op-
erating modes�
The chronothermostat comes in three colours:
white, silver (CH151RF series) and anthracite
black (CH152RF series)�
