ENERGY BALANCE
Synergy program
The synergy program Energy Balance is a pre-defi ned
program containing a sequence of operating commands
for roller shutters or awning blinds. If the program has
been enabled, the sequence is automatically started at the
pre-defi ned times. The times have been fi xed so that the
sunscreening products will run up or down depending on
whether it is summer or winter and day or night.
During the summer time in Southern Europe, the sun-
screening products will for instance run down in the morn-
ing and up in the evening. In this way, the sun is screened
during the time where it induces considerable heat into
the building. This means less need for inducing energy for
cooling of the building.
Control parameters
The control of the sunscreening products is automatic-
ally changed so it matches the summer and the winter
period. The program will automatically be disabled in
the transition period between summer and winter where
automatic operation of the sunscreening products does not
contribute substantially to improving the energy balance.
The transition period is 0 to 8 weeks depending on the
geographical location. In addition, the control automatic-
ally discerns between weekdays and weekend so that the
sunscreening products are not operated before 8 o'clock in
the morning at weekends.
Settings
The program can be enabled in two ways:
• Standard setting: Automatic control of the roller shut-
ters alone.
• Customised setting: Automatic control of selected roller
shutters and awnings blinds. In addition, the location of
the windows in the building (north/south/east/west) is
taken into account.
The following examples show how to enable the program
Energy Balance, fi rst via Standard setting and then via
Customised setting.
