Operation and Adjustment
The timer can be used to program 3
preset times.
The 3 preset times can either all be
spread over one weekday or be spread
between different weekdays.
In water heaters and if a temperature
sensor is connected to the timer the
heater start is automatically calculated
depending on the measured room tem-
perature and the selected heating level
(ECO or HIGH). The operating time can
be between 5 and 60 minutes before the
programmed departure time, whereby
operation is always stopped 5 minutes
after the programmed departure time.
Therefore, the minimum possible operat-
ing time is 10 minutes and the max pos-
sible operating time is 65 minutes.
In this case, the operating time set in the
“set time” menu (page 8) is ineffective.
In all other configurations the start takes
place according to the preset operating
time.
General information on programming the preset time
Identical preset times
If several identical preset times are
programmed for a specific weekday in
programs 1, 2 or 3 the last entered preset
time is valid. When the timer is activated,
the identical preset times saved are
deleted.
If identical preset times are programmed
for different weekdays there is not conflict.
Overlapping of preset times
Example:
You have set the “Heater” operating mode
on a weekday for your departure time at
13 hrs. At the same time the ”Ventilation“
mode has been programmed for the
same day for 12.45 hrs and with an oper-
ating time of 15 minutes. What happens?
The timer calculates the start of heating
for the ”heater“ mode which, depending
on the ambient temperature measured
can lie between 5 and 60 minutes before
the programmed departure time. If the
calculated heater start is after 12.45 hrs,
the vehicle is ventilated between
12.30 hrs and 12.45 hrs and is then
heated.
If the calculated heater start is before
12.45 hrs, the vehicle is heated until
12.30 hrs, then the heater is stopped and
the heater switches to “ventilation” mode.
After the set “ventilation” mode operating
time has expire the heater switches off.
• The preselected times are always
departure times, even if runtime calcu-
lation is deactivated.
• You cannot program more than 3 pre-
selection times.
• The maximum operating time of 65 min-
utes for automatic runtime calculation is
a factory setting. If necessary, this can
be reduced by the installation workshop
to a minimum of 15 minutes.
