5.6 Set holiday program
Menu: Holiday
If you are going away for some time, or taking some time off for
a few days, you can set the holiday program. If the heat pump is
set to heating mode according to the settings for summer/
winter mode you use the holiday function. With the holiday
program the heating is set very low according to the time
program for "Saturdays", or to no heating at all.
You may decide to switch off the heating of hot water
completely during the holiday. The default settings guarantee
energy efficient and safe operation during your holiday. The
display shows to which date the holiday program is active
during the holiday period.
Fig. 4 Initial menu during the holiday period.
The settings and use of the holiday program do not change the
other time programs. When the holiday program has been
completed the control unit works with the set time programs
again. The holiday program is automatically deleted once it has
finished.
A detailed description of how to set the holiday program is
given in table 27 from page 26.
