Proline Edition X cooling thermostats

Starting up
YACE0100 / October 4, 2018

Each program begins with the segment "Start". It defines at which temperature
Segment 1 is to continue the program. It is not possible to specify a time for the Start
segment. For thermostats without cooling ability, the start temperature must be
selected higher than the bath temperature, which prevails before the program start.
Without the Start segment, Segment 1 would be different depending on the bath
temperature at the start of the program.
Edited program example (see dashed curve in the graph on previous page).


The field tolerance (refer to the above program table and the graph below):

It facilitates exact conformance to the dwell time at a specified temperature. Segment
1 is not processed until the bath temperature is within the tolerance range

, so that
the ramp (Segment 2) starts delayed at

.

A tolerance range which is too tight can however also cause undesired delays. In
particular with external control the range should not be chosen too tightly. In
Segment 5 a larger tolerance has been entered, so that the desired time of ten
minutes is maintained even with settling action

.

Only flat (slow) ramps should be programmed where necessary with a tolerance
range. Steep ramps which lie close to the maximum possible heating or cooling rates
of the thermostat may be severely delayed by a tolerance range that is too tight (here
in Segment 2)

.
Example for the influence of the tolerance field input
in case of external bath temperature control:
The setpoint temperature of the programmer is
shown in grey.
The actual temperature in the external bath
container is represented as a continuous line.
