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 possible - 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 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.

The front side

1 - Graphic display: displays the messages which determine the programming operations as well as the system status
2 - Selection Keys: these let you cycle through the functioning modes inside the menu, if any, while the main screen is being viewed;
3 - OK Key: accesses the main menu, confirms the selection displayed or the data entered
4 - Sensor: measures the ambient temperature
5 - C Key: cancels the selection and returns to the previous page; if held down, it returns to the initial page
6 - Scroll Keys: these let you change the set temperature while the main screen is being viewed; when inside the menu, you can scroll the list of the options available
