A56: Alarm suppression time after "control ON" or set point change
After switching on control, especially with cooling systems, it takes a
certain time before the operating temperature is reached. There would
then be an unwanted alarm. Therefore, through parameter A56, an
elapsed time can be set, during which no alarm is signalled.
A60: Sensor selection
The parameter is set for the desired sensor type.
A80: Temperature scale
The display can be switched between Fahrenheit and Celsius. With the
conversion, the parameters and set values retain their numerical value
and setting range. (Example: A controller with a set point of 32 °C is
switched to Fahrenheit. The new set point is interpreted as 32 °F, which
corresponds to a temperature of 0 °C).
For information on troubleshooting, see chapter 9 "Faults".
