Setting the To select the desired temperature with knob 1 it is ne-

temperature . cessary to operate key 6. While the key is depressed the

digital temperature indication 7 switches to setpoint se-

lection resp. nominal value indication, indicated by a

blinking point in the display.

The setpoint indicated can only be changed with knob 1 when

key 6 is pressed* If knob 1 is moved quickly, the setpoint

is adjusting in large steps while it changes in single

steps upon slow operation. After releasing of key 6 the

setpoint adjusted is still shown for a short time (blinking

point)•

Thereafter it switches automatically on the actual value.

Then scale can be locked with the screw la to prevent

unintentional changes.

When key 6 has not been operated the digital display 7

always indicates the actual temperature inside the chamber.

Operating the key displays the selected temperature setting

(blinking

point).

Set the adjustable overheat contoller TWW with knob 9 above

the selected working temperature by an appropriate amount

(e.g.

5°C). This scale can also be locked. The selected

setpoint of the overheat controller TWW can always be read

on the temperature display 12.

Putting into Set the main switch, rotary knob 2, to position I. The

operation green signal lamp 3 shows that the oven is ready for opera-

tion.

After switching on the minimum temperature (20°C) is indi-

cated.

The yellow signal lamp 4 indicates the state of the hea-

ting.

Steady conditions have been reached when the desired tem-

perature can be read on the built-in digital temperature

indicator. 7 for several tiires (during a period of at least

minutes).

In order to provide optimum protection of thermic sensitive

load against overtecnperature in case of failure of the

thermostat, move the overtemperature controller TWW now

down with the knob 9 until it just does not operate.

This setpoint-reduction should be effected very slowly step

by step for one digit (resp. one rest) exiguously above the

actual steady temperature (approx. 3°C resp. at incubators

approx.

0,5°C).

Fault:

If the selected operating temperature is exceeded

due to a fault in the temperature control circuit, the

temperature control is taken over by the overtemperature

controller as soon as the temperature set with rotary

knob 9 and shown on display 12 has been reached. This is

indicated by alternate flashing of the red signal lamp 5.

The unit must be checked immediately by a qualified elec-

trician.

In case of a short switching off (up to 10 sec.) the

setpoint can be seen on the display.
