When the thermostat is in Optimum Start mode, the thermostat will try
to reach the target temperature by the start time of the next switching
time. This is done by setting the Ti (time interval) on the thermostat in
this menu to 10, 15, 20, 25 or 30. This will allow the thermostat 10, 15,
20, 25 or 30 minutes to increase the room temperature by 1°C.
Ti can be set when OS is selected in the installer menu.
