GENERALITIES
This device is a battery-powered digital weekly chronostat for
controlling room temperature on three levels: Comfort, Economy
or Off/Antifreeze.
Its main characteristic is the lack of electrical connections; indeed
the ON and OFF signals are transmitted to the receiving unit by radio,
making this device easy and cheap to install, especially when there is
no existing electrical system available.
The chronostat can be used in both heating and air conditioning
systems and it features a large backlit display which shows
all functional indications, the program schedule and the room
temperature reading or, alternatively, the current time.
It allows to set up to 7 different time schedules, each one different
for each day of the week, with a minimum intervention time of 1/2
hour during the 24 hours.
