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).
