The standard digital timer/combination timer 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.
The standard digital timer features a wakeup alarm function. The
combination timer has a temperature controller. The combination
timer can only be used on Air Top 2000 heaters which allow the
temperature to be preselected.
When the ignition switched on, the timer displays the current time
and the day of the week. When the heater is switched on, the display
and the 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. No
display occurs in TRS vehicles.
The timer can be operated in that all flashing symbols can be
adjusted by means of the and buttons. If the buttons are not
pressed within 5 seconds, the time displayed will be stored. 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.
On heaters equipped with a fault diagnosis system (Air Top 2000 and
Thermo 90), a number, i.e. the error code, may be flashing on the
display. In this case, please consult your Webasto dealer.
