OPERATION
Acoustic Feedback (Buzzer)
Timer-function (optional)
The following activities occurring during operation of the TC unit are fed back audibly via a
buzzer: Short single tone for regular actuation of a key Longer, intermittent tone for perma-
nent use of keys over a longer period of time (10 sec) Expiry of the timer
The timer function is available in two types:
- Stand-alone-timer 1..99 min: Audible signal with timing. This function can only be activat
-
ed as long as no cooking zone is in operation (all stages = 0). Is any cooking zone started
with operation (level >0) than the stand alone timer keeps in operation. If the timer shall
be used to cut off a cooking zone (see cooking zone timer) then the control must first be
switched off (power sensor) and switched on again.
- Cooking zone timer 1..99 min: This function can only be activated as long as a cooking is
active (stage < 0; display dot). Audible signal with timing, four cooking zones to be cut off
are freely programmable.
Setting a timer value:
By adjustment with the slider area.
Primarily the adjustment of the first digit takes place and thereafter the adjustment of the
second digit. Within 10sec after the adjustment of the second digit the value might be re
-
set. (Illuminated display dot in the timer display and in case of a cooking zone specific timer
a blinking assigned LED).
In case of an active timer display the timer value may be set to [0] directly by pressing [0]
on the slider area (left side)
Switching of an active timer:
A timer can be switched of by setting its value to 0. A stand
alone timer can be switched of by a double actuation of the power key “1”.
Timer Stand-Alone:
If the control unit is switched on (all cooking zone displays show [0]),
the stand-alone timer may be activated by pressing the timer select key. The timer display
show “00“. The decimal dot on the timer display flashes. The timer is cut off after 10 sec
(black display) if no further settings are made. In case of a timer value is set with no activa-
tion of a cooking zone within 10sec
the cooking zone displays are cut off (interposing relays are also cut off). Possible optic
warnings for hot cooking zones [H] are displayed permanently
As long as the timer is selected (display dot flashes for 10 sec) it can be set. The setting
range is 0 -99 minutes in single steps; by Slider area.
Directly after the timer value is set countdown starts with the last set value. The timer is
deselected automatically after 10 secs and the timer display indicates the timer value. After
expiring of the set time an acoustic signal is given and the timer display flashes •00“.
