4.3.11.6- Description of the Time Schedules sub-menus The control provides two timer programs: schedule 1 and schedule 2 that can be activated if the unit is equipped with an optional CCN/clock board (if the CCN/clock board is not installed, the two schedules are permanently in occupied mode).

The first timer program (schedule #1) provides a means to automatically switch the unit from an occupied mode to an unoccupied mode: the unit is started during occupied periods.

The second timer program (schedule #2) provides a means to automatically switch the active setpoint from an occupied setpoint to an unoccupied setpoint: cooling setpoint 1 is used during occupied periods, cooling or heating setpoint 2 during unoccupied periods. Heating setpoint 3 is activated during holiday periods. For additional information on set-point activation see section 5.6.1.

Each schedule consists of eight time periods set by the operator. These time periods can be flagged to be in effect or not in effect on each day of the week plus a holiday period (see section

4.3.11.7on public holidays). The day begins at 00.00 hours and ends at 24.00 hours.
