Teach In
"Automatically
cyclically" "Automatically cyclically" means that the Teach-In values are temporarily
saved again at intervals of 1 minute. This setting is particularly suitable for SIC
heating elements as in this case the resistance in the load point changes with
time due to aging.
When the power controller is disconnected from the supply voltage, the
Teach-In values are deleted again. After another power ON, the power control-
ler resumes automatic Teach-In detection.
6.2 Manual mode
In this case, the setpoint value can be manually preset in % without the need
for external wiring via the analog input.
6.2.1 Default setpoint value in manual mode
Starting Manual mode, as set ex works, can be accessed without entering a code.

tus.
