The setpoint (T

) can be input within the unit temperature range but not higher than the
current overtemperature switch-off point. When the input is too high, pressing
does not enter the value but instead produces the message

Pressing the
key several times in the SHIFT mode (green LED in SHIFT key
alight) leads successively to the input functions described below.
9.4.1 Auto-adaptation
Here it is possible to start the controller auto-adaptation by the input of 1 (SHIFT OFF)
and pressing the
key.
There should be the largest possible difference between the bath temperature and the
setpoint to be entered subsequently, i.e. the time to reach the setpoint has to be longer
than 5 min, preferably 10 min. In addition, auto-adaptation is obviously possible only
during a heating or cooling phase which is actively influenced by the energy sources
available.
Example 1:
intended operating temperature approx. 70°C:
1.
set the setpoint to 70°C
2.
within 1 minute start auto-adaptation at the PAR level, e.g. at a
bath temperature corresponding to the ambient temperature
On reaching the setpoint the auto-adaptation switches off automatically, and the result
of auto-adaptation can be indicated at the control parameter level
(see Item 9.6).
