Please note: The room unit does not have an internal clock. The precise time is
periodically synchronized with the controller (master).
The weekly and daily schedule for the time switch catalog (so-called "scheduler")
can be programmed:
• for all 7 days of the week.
• Daily with up to 6 switching entries (referred to as "Entry")
You can do the following when setting up the entries
• determine a switching time and
• select the state to be run in Auto mode.
Possible state assignments (e.g. 0=Off, 1=EcoSt1, 2=ComfSt1, etc.) are predefine-
d as part of the controller configuration. A max. 7 states are possible.
The selected operation is automatically run at the defined time after the entry is
setup.
The following button assignments are enabled when programming the scheduler:
• PROG —> Cancel.
• OK. —> Confirm.
The workflow includes explanations of the individual steps from a technical view-
point. As a practical matter, individual steps may not be needed, while others must
be repeated, etc. As a result, we are listing an example in this section that illus-
trates a practical example on programming a room unit.
1. Press PROG
(the display goes to
display through the days of the week).
2. Select weekday with plus and minus (1=Monday), then confirm selection
with OK.
Note: The same settings apply to the selected days. You must proceed
through the entire instruction chain to program different settings for certain
days.
3. Conduct weekdays through day 7 as per step 2.
4. 1 time (!) press the plus button.
You now see the selected days; a flashing bar appears above the numbers.
5. Confirm selected weekdays: 1 time (!) press OK.
The display changes to the first entry page, the state is "00X", time is 00:00
:Do not change the time for this entry!
Three entries per day are prepared and may vary depending on the configured
plant, e.g. State 001 at 00:00 am, state 002 at 08:00 am, state 001 at 6:00 pm. The
entries do not need to be entered in chronological order.
The following illustrates how to create a new (the fourth) entry.
