Switching program
The switching program can be used as a 7-day or 24-hour switching program, depend-
ing on programming. It is also possible to select one of the continuous operating modes
with which the switching program is not used.
With the 7-day switching program, it is possible to program all days individually, the
working days (1-5), the weekend (6-7), or the entire week (1-7).
When a heating period is programmed, 3 different switching patterns are available.
It is possible to select 1, 2 or 3 heating periods. For each heating period, the start time,
end time and comfort setpoint are to be entered. In between heating periods, it is al-
ways the same economy temperature setpoint that is used. This economy temperature
setpoint can be adjusted on the temperature menu.

Holiday function
The holiday function is to be selected on the user menu. Set the start of the holiday
period (day of departure/
/ day of week), the duration and the temperature
setpoint (
) during your absence. This will enable the controller to maintain the re-
quired temperature for a period of up to 99 days. Every midnight, the counter subtracts
one day.
When the holiday period is over and the counter reads 00, the controller will resume the
operating mode selected last.

Using a suitable remote operator unit, the controller can be switched to an independ-
ently adjustable economy temperature

bol
will appear on the display. When the contact opens, the operating mode se-
lected last will be resumed.
