Program Your Schedule
The TH144 allows four setting changes for each day of the week.
There are no pre-set programs.
For each day, enter the time at which you wake up (P1), the time you
leave for work (P2), the time you return home (P3) and the time you
go to bed (P4):

NOTE:
For temperature increases (P1 and P3), allow at least 15
minutes per 1°C (2°F). For example, if you have lowered the temper-
ature by 3°C (6°F) during the night and you wake up at 7 a.m., pro-
gram the change for 6:15 a.m.
To reduce energy costs, you must lower the temperature for a period
of 2 to 3 times the delay required to bring the temperature back to
your comfort level.
3.1.1 Set or Modify the Programs
• After 60 seconds of inactivity, the thermostat will automatically exit
programming mode.
• It is sometimes faster to program the same schedule for the entire
week and then modify the exception days.
