5.8.2 Activating / deactivating time band operation
Information
Time band operation cannot be activated if the action all four time bands is set to ON or OFF.
Procedure
1. Make sure the operation of the system is activated (see the section "System ON / STANDBY").
2. To activate / deactivate time band management, press CLOCK: symbol 17 comes on / goes off.
During time band operation:
• The display shows the operation of the system with symbols 1, 2 3, 4 or 5; if none of these symbols
is on, the system is in TEMPORARY STANDBY;
• Briefly pressing the ON button switches from ON to TEMPORARY STANDBY and vice-versa
("override" bands) until the next time band starts (in this case, OFF is not shown on the display);
• The mode set by the MODE button is not affected by time band operation.
3. To switch the system to STANDBY (NON-TEMPORARY) hold the ON button until "OFF" is displayed;
4. To restart the system, press the ON button: time band operation will be reactivated and the action
defined for the active band will be performed.
Additional information
After an extended power failure in which the clock settings are lost, the system will restart in ON mode, not
managed by time bands.
