USEFUL TIPS AND TYPICAL SETTINGS
When setting the times for the heating periods it is useful
to remember that it might take up to an hour for the
house to become warm, expecially in colder weather.
Also the effect of the central heating will remain for a
time when the central heating is turned off.
A typical timer setting for a working family could be as
follows:
A group of five days (Monday to Friday) set with the first
heating period set to come on at 6:00 and off at
then the second period set to come on at 16:00 and off
at 22:O0. A second group of two days (Saturday and
Sunday) set with the first heating period to come on at
8:00 and off at 1O:OO; then the second period set to
come on 16:00 and off at 23:O0.
Do not forget that if your require heating during a central
heating off period, symply set the operating mode switch
to I, remember this switch must be reset to AUTO at a
later date for the timer to return to its programmed settings.
