The TH140 allows four setting changes for each day of the week. There are no pre-set programs. Your heating system switches betw- wen the Comfort setpoint and the Economy setpoint according to the times you would have set.

For example, enter each day the time at which you wake up (PROG 1), the time you leave for work (PROG 2), the time you return home (PROG 3) and the time you go to bed (PROG 4):

Programs	Associated Setpoint	Time
PROG 1	(Comfort)	Wake-up
PROG 2	(Economy)	Leave
PROG 3	(Comfort)	Return
PROG 4	(Economy)	Sleep

Note: For temperature increases (PROG 1 and 3), allow at least 15 minutes per 1°C (2°F). For example, if you have lowered the temperature by 3°C (6°F) while you sleep and you wake up at 7 a.m., change the setting at 6:15 a.m.
