5.13 - Time schedule function
The control includes two time schedules.
The first schedule
(schedule 1 OCCPC01S)
allows automatic
changeover of the unit from occupied to unoccupied mode:
the unit is started during occupied periods.
The second schedule
(schedule 2 OCCPC02S)
allows automatic
change of the active setpoint (if auto mode is selected) from
the occupied setpoint to the unoccupied setpoint.
Cooling or heating setpoint 1 is active during occupied
periods. Cooling or heating setpoint 2 is active during
unoccupied periods.
Each time schedule consists of eight user configurable
periods. Each of these periods can be validated as active or
not active for each day of the week as well as for holiday
periods. The day begins at 00:00 and ends at 23:59.
The schedule is in unoccupied mode unless a time period is
active. If two periods coincide or are active on the same day,
priority is given to the unoccupied period. Each of the eight
periods can be displayed and modified using a sub-menu.
The following table shows how to configure a period. The
method is the same for time schedule 1 and 2.
To access and configure them see the table below. Also refer
to chapter 4.10 - Time schedule screen.

5.13.2 - HOLIDAYS menu
This function is used to define 16 holiday periods. Each period
is defined by three parameters: month, start day and holiday
period duration. During the holiday periods the controller
is in occupied or unoccupied mode, depending on the periods
validated as holidays. Each of these holiday periods can be
displayed or modified using a sub-menu.
ATTENTION: The Broadcast function must be active for
the holiday function to operate, even if the unit is in
autonomous mode (not connected to the CCN network).

5.14 - Option 156 - energy management option
This option requires the installation of an additional NRCP2-
BASE EMM type board. This board permits access to the
following functions:
• Reset via 4-20 mA control: see chapter 5.7.2.
• Ice storage contact: if ice storage control has been
configured (configuration menu => General configura-
tion), this contact permits activation of the ice storage
setpoint.
• User safety loop input: this contact is used for the
customer safety loops that require a unit shut-down if
it is closed.
• Occupancy control time schedule override contact: if
this contact is closed, the unit enters the occupied
mode for a configurable override time of 1 to 4 hours.
•
Condenser water flow input.
• Demand limit setpoint contact and output: see chapters
3.7.4 and 5.8.
This option also permits display of the following data:
• Current unit capacity via 0-10 VDC. output
• Operating status, compressors A and B
• Unit completely stopped
• Unit in operation
