INTRODUCTION
The weekly-setting wall mounting chronothermostat suitable for heating and/or cooling systems, is equipped with a big, clear
display (some models have the backlight function) so as to monitor all functions in real time.
Its principal feature is the ease with which it can be programmed, in fact, despite the number of functions it has, it is very simple to
use. Various programmes are already set in its permanent memory, at 3 and 4 temperature levels, designed to provide maximum
comfort. However, only a few seconds are needed to set the preferred temperatures to be applied throughout the day (even every
30 minutes!) and also for each day of the week. A standard function of the chronothermostat consists of the automatic adjustment
of the temperature in the ON/OFF differential mode, so as to adjust itself to the thermal inertia of your particular system - the
temperature can be set between 0.2°C and 2°C. Otherwise, you can choose the function in proportion with the cycles, which can be
set to last 7-10-15-20 minutes, thus reducing the operating time of the boiler, which depends upon the difference between the set
temperature and that of the room (the smaller the difference in temperature, the less time the boiler functions).
Moreover, the chronothermostat can automatically anticipate ignition (intelligent function), for the room to reach the desired
temperature at a particular time. The set temperature scale is in degrees centigrade (Celsius) and you can calibrate the
measurement of temperature by setting a correction value (from -1.9 to +1.9 °C). When switched to degrees Fahrenheit, all
temperature settings are updated according to the new temperature scale.
Particular attention has been given to the energy saving factor: the Holiday function, the interruption function for domestic cleaning,
the option to block the set temperatures, the anti-freeze temperature can be set between 4 and 12 °C, telephonic control (optional
telephone programmer). These prevent energy from being wasted, which leads to economic savings (refer to the following pages
for the description of these and other functions).
