7.2 Display mode
C The actual temperature is displayed. Indicator is lit up, status indicater of target temperature (35) is off.
Pressing the pushbutton (36) once will display the target temperature stored. The status indicator for target tempera-
ture (35) lights up. After about 5 sec., the indicator changes back to the actual temperature.
7.3 Setting mode for target temperature
The factory setting for the target temperature = 24°C (75°F).
How to set the temperature:
D Press and hold the pushbutton (36) for approx 3 sec. The target temperature blinks (temperature indicator (34) and
the status indicator for the target temperature (35) blinks).
E Set the desired target temperature by pressing the pushbutton briefly. Pressing once = increase by 1°C (2°F).
When the maximum set point of 34°C (93°F) is reached, the indicator will begin again at 18°C (64°F).
F When the desired target temperature is set, wait until the indicator blinks again. Then press and hold the pushbutton
(36) for approx 3 sec. in order to store the desired target temperature. After 15 sec. without an entry, the indicator re-
