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-
