Setting the
temperature
Putting into
operation
To select the desired temperatures with knobs 1 resp. 15 it
is necessary to operate keys 6 resp, 14• While the keys are
depressed the digital temperature indications 7 resp. 16
switch over to setpoint selection resp. nominal value
indication, indicated by a blinking point in the corres-
ponding display.
The setpoints indicated can only be changed with rotary
knobs 1 resp. 15 when keys 6 or 14 are pressed. If rotary
knob 1 resp. 15 is moved quickly, the setpoint is adjusting
in large steps while it changes in single steps upon slow
operation. After releasing of key 6 resp. 14 the setpoint
adjusted is still shown for a short time (blinking point).
Thereatter it switches automatically over to the actual
value. The scales can be locked with the screws la and 15a
to prevent unintentional changes.
When keys 6 resp. 14 have not been operated the digital
displays 7 resp. 16 always indicate the actual temperature
inside the chamber. Operating the key displays the respec-
tively temperature setting (blinking point).
Operation time of both regulators is adjusted by programme
timer 13. Time of operation for temperature regulator 15,
is adjusted by pushing individual switch buttons (red sec-
tion is visible).
If switch buttons are not pushed (black section is vi-
sible) , temperature regulator 1 is in operation. The opera-
tion of each regulator is indicated by signal lamp 17
and 18.
Time (actual time) can be adjusted by turning timer
(direction of arrow).

Set the main switch, rotary knob 2, to position (3 • After
switching on the previous setpoints are indicated (they are
stored for approx. 1 month). The prograirme runs continual-
ly. Switching off by hand with main switch 2 to position 0.
Function of safety regulator is the same as under

Normal
As there is only one overheat controller, its temperature
nominal value has to be set about 5°C above the respec-
tively higher set nominal value of one of the both (pro-
gramme-) temperature controllers.
For example:
Temperature controller 1
Temperature controller 2
Overheat controller
nominal value 70 °C
nominal value 110°C
about 115°C
The heating and cooling times until the appropriate setpoint is reached
depend both on the load inside the oven and on the ambient temperature and
must be taken into account when setting the timer riders.
An example is shown in the illustration below:

Actual time 10.00 hrs. Temperature controller 15 was in operation between
8.00 and 9.30 (riders pushed in). Temperature controller 1 is now opera-
ting. Change-over back to controller 15 at 11.15.

Select the temperature as described under "Operation with
prograrmie-controller". Set knob 2 of the main switch to po-
sition (3 • Turn rotary knob 19 clockwise up to the stop,
and then turn it back to the required time setting. The
oven switches off when the set time has elapsed.
