Introduction
The CH150RF/151RF/152RF programmable
thermostat measures the ambient temperature
and controls the heating (conditioning) system
through a radio connection with an actuator. A
humidistat can also be driven. The operating
mode can be either chosen from among the
preset ones or customized to one’s own needs.
The large display shows the temperature pro-
fi
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 programmable thermostat is battery pow-
ered. 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 programmable thermostat:
• Radio actuator
• Separate temperature probe
• Telephone actuator for
fi
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 programmable ther-
mostat, to be informed about the ambient tem-
perature or the heating / cooling system status;
• remotely manage the programmable thermo-
stat operating modes.
The programmable thermostat comes in three
colours: white, silver (CH151RF series) and
anthracite black (CH152RF series).
