Auto: Program controls temperature
Manual: Press p/q to set temperature
Auto: In this mode the thermostat follows a program
schedule to maintain a comfortable temperature when you
are home and reduce energy costs while you are away (see
pages 12-13).
Manual: This mode turns off the program schedule to
maintain a constant temperature. Press the p or q
buttons to set the temperature you want. The temperature
will remain at the level you set until you change it, or until
you press AUTO to resume the program schedule.
Off: When the thermostat is off, the heating system runs
only as needed to maintain a minimum temperature to
protect your home. This level is set at 5°C, but you can
change it if necessary (see page 28).
