Combination timer
General infor-
mation
The combination timer allows the heater start time to be selected for
a period of up to seven days.
Three cut-in times can be programmed, although only one of them
may be activated.
The combination timer has a temperature setpoint generator.
When the ignition is switched on the timer shows the current time
and the day. When the heater is operating, the display and the but-
tons are lit.
When the timer is connected to the power supply all the symbols in
the display will flash. The time and day must be set. The display re-
mains blank in ADR vehicles.
Operation
The operation of the timer is designed such that all the flashing sym-
bols can be adjusted using the
and
buttons. If no button is
pressed for five seconds the displayed time is saved. If the
and
buttons are pressed for longer than two seconds, they will switch to
high speed adjustment.
If the ignition is switched off whilst the heater is in permanent heat-
ing mode, a remaining operating time of 15 minutes will appear on
the display and the heater will continue to operate.
Error code
On heaters that output an error code (Air Top 2000 ST), a number,
the error code, may appear in the display. In this case you should visit
a Webasto service outlet.
