Operating Manual
Using the schedule
Press the Run button to follow the programmed schedule. For maximum energy savings
while maintaining comfort, you can program the schedule such that the temperature is at an
economical level when you sleep or leave for work and at a comfortable level when you are
ENGLISH
awake and at home. You can program up to four periods per day:
Wake Starts when you wake up
Leave Starts when you leave for work
Return Starts when you return home
Sleep Starts when you go to sleep
To program a period, you need to set its start time and its two temperature settings (one
when the thermostat is in cooling mode and another one when it is in heating mode). The
same settings are used every day from Monday to Friday and another set of set tings are
used for Saturday and Sunday. For example, you could program all four periods for the
weekdays but only two periods (Wake and Sleep) for the weekends.
