The 4451 Chronothermostat is a fl ush-mounting device which can be used
for heating and air-conditioning systems; it is possible – through several
programming possibilities – to adjust the temperature at any time of the
day and in a diff erentiated 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 specifi c 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 setting, 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 batteries more easily.
