Introduction and standard functions
General information

The 4451 Chronothermostat is a flush-mounting device which
can be used for heating and air-conditioning systems; it is pos-
sible – through several programming possibilities – to adjust the
temperature at any time of the day and in a differentiated manner,
every day of the week.
It is possible to choose how to use a standard program (already
stored but can be changed according to the specific needs of
the user) or to create a new one with a simple programming
procedure.
A large back-lit display shows you at all times the programme set-
ting, the status of the system and the temperature of the room.
The Chronothermostat consists of a base used for the system
electric connections and a removable front part to allow the user
to execute the programming operations and to replace the bat-
teries more easily.
