General
Operation
The 7 day timer with 3 time settings enables you to preset the
start of the heater operation up to 7 days in advance.
It is possible to program 3 different starting times, only one of
which can be activated at any one time and one event (desired
programmed event must be initiated each time required).
When the ignition is switched on, the timer displays the current
time and day of the week. When the heater is switched on,
the display and buttons are illuminated.
After the power supply has been connected, all symbols on the
display will flash. The current time and weekday must be set.
The timer can be operated in that all flashing symbols can be
adjusted by means of the and buttons.
If no adjustments are made within 5 seconds, the current
setting displayed will be stored in memory. If the and
buttons are pressed for more than 2 seconds, the fast
time-setting mode is activated.
If the ignition is switched off while the heater is operating in
the continuous mode, the remaining operating time of 15
minutes is displayed and the heater continues to operate for
this period of time.
Whenever power supply is disconnected, all programmed
settings will be lost.
