ITCS (Optional)
The thermostat Intelligent Temperature Control System will activate your installation in advance to
assure the desired temperature at the hour programmed following your weekly program.
This automatic control system works in the following way:

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.
