beginning a run or between runs. Once a run is initiated,
the pre-heat automatically stops.
Note that the pre-heat function is only enabled if the
temperature set point is different than “no”.
4.
Temperature display
- Indicates the set temperature or
the actual temperature during a run in °C. The
temperature set point can be set from 35°C to 80°C at a
5°C interval. In addition, it is possible to set the
temperature to “no”, which means that heating will not be
applied during the run. The temperature setting of “no”
can be reached under 35°C or over 80°C.
5.
Time display
- Indicates the heat timer or the run timer
set points. During a run, it indicates the elapsed or
remaining run time or the remaining heat time. The range
for these timers is from 0.01 [1 min.] to 9.59 [9 hours, 59
minutes] at a 1-minute interval. In addition, it is possible
to set the heat time to “CCC”, which represents a
continuous heating throughout the execution of a run.
The setting of “CCC” can be reached under 0.01 [1 min.]
or over 9.59 [9 hours, 59 minutes].
