SCHEDULES
Two schedules, one for weekly switching points and one for
holiday switching points, are available. These schedules and
the clock/date are stored in the memory (EEPROM) of the
device. The battery maintains the correct time in the event of
power loss.
NOTES:
• When the battery is running low, the display provides
an indication of this (see Fig. 17).
• Weekly switching point default settings are:
— Occupied mode: Monday through Sunday from 6
AM to 6 PM (switching point 1).
— Night mode: Monday through Sunday from 6 PM
to 6 AM (switching point 6).
— All other switching points are empty.
• Holiday switching point default settings are:
— Off: 24 hours a day (switching point 1).
— All other switching points are empty.
Standard Schedule
The standard schedule switches controller mode (off, night,
occupied or unoccupied) at programmed switching points
(S1 through S6). These points can be set for:
• Weekdays.
• Weekday groups.
• Holiday types (H1, H2 and H3).
When the occupied or unoccupied mode is taken from the
schedule and an occupancy switch connected, control mode
is determined by occupancy input:
• Occupied (contact closed): Controller mode is occupied.
• Unoccupied (contact open): Controller mode is
unoccupied.
NOTE: Off and night control modes are not influenced by
occupancy input.
The clock automatically changes controller mode according to
the programmed schedule. In unoccupied or night mode, the
SOFFS
or
NOFFS
is added to (cooling) or subtracted from
(heating) the calculated control point. A one-week schedule
with up to six switching points per day can be programmed in
advance and repeated weekly.
Holiday Schedules
Three different holiday schedule types (H1, H2 and H3) can
be programmed with up to six switching points per day. One of
these types can be assigned to each date of the year—01.01
(January 1) to 12.31 (December 31).
NOTE: Schedule times and modes of utilized holiday types
(H1, H2 or H3) must be programmed in the standard
schedule.
Table 10. Holiday Schedule Types.
a
H2 is typically used to preheat or precool the space before
the first occupied day.
NOTES:
—
H0 indicates absence of holiday and the weekday
schedule applies.
—
H1 and H2 holidays are not influenced by
manually changing today’s date.
—
When power is interrupted for more than one day,
all H1 and H2 holidays within that period are
deleted.
