4.5.7.6- Description of the Time Schedules
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 (when auto mode is selected) the active setpoint from an occupied setpoint to an unoccupied setpoint. Cooling or heating setpoint 1 is used during occupied periods. Cooling setpoint 2 is used during unoccupied periods. For additional information on setpoint activation see section 5.7.1.
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 4.5.7.7 on public holidays). The day begins at 00.00 hours and ends at 24.00 hours.
Program is in unoccupied mode unless a schedule time period is in effect. If two periods overlap and are both active on the same day, the occupied mode takes priority over the unoccupied period.
Each of the eight periods can be displayed and changed with the aid of a
