The program stops or can be stopped and the LED turned off in one of three ways:
1. If the set temperature has been reached before the set time has elapsed,
the temperature will be maintained until the time has elapsed. The control
then changes over to the storage program.
2. If the set temperature is not reached before the set time has elapsed,
chilling continues until the set temperature has been reached. The control
then changes over to the storage program.
3. Each program can be stopped manually by pressing and .. The
LEDs will go out. If programs are switched off in this way, a defrost follows
and the control changes over to the storage program.
Changing temperature
and time settings
The temperature or time setting can be changed by pressing and an arrow key at
the same time:
for setting a higher temperature or longer time.
for setting a lower temperature or shorter time.
When is released, the new setting is stored.
NOTE: The time or temperature setting can be changed during the program
sequence for time and temperature-controlled chilling as follows:
First press one of the program keys . The red LED will flash.
Time and temperature can now be set as described above. The program key
concerned must then be pressed again. The red LED will then light up continuously.
Memory.
All settings are stored in the control memory, until new values are entered.
Therefore, the same program can be repeated without reprogramming.
Door monitoring
To minimise cold loss, the evaporator fan is stopped each time the door is opened
and a monitoring time of 3 minutes begins. If the door is not closed during this time
interval, the compressor stops. If the compressor does not start immediately after the
door is closed, the reason might be that the protection system built into the
compressor control is preventing the compressor being started too quickly. See
section on compressor monitoring.
