The Intelligent Temperature Control System will
activate your installation in advance (2 hours
maximum) to assure the desired temperature at the
hour programmed following your weekly program.
This automatic control system works in the following
way:
When you start your thermostat for the first time, it will
measure the time taken by your installation to reach
the set temperature. The thermostat will re-measure
this time at each program change to compensate
external temperature change & influence. You can now
program your thermostat without the need to adjust the
temperature in advance because your thermostat does
it automatically for you.
