6. Special
functions
Caution
Other than the time all settings may
only be made by a specialist.
This menu is used to set the current time and date.
6.1 Time & Date
Caution
For proper functioning of the controller and statistics for the system data
it is essential for the time to be set accurately on the controller. Please
note that the clock continues to run for about 24 hours if the mains volta-
ge is interrupted, and after that has to be reset.
Deviations in the temperature values displayed, for example due to cables which are
to long or sensors which are not positioned optimally, can be compensated for manu-
ally here. The settings can be made for each individual sensor in steps of 0.5°C.
Offset S1...S6 per setting range: -10°C...+10°C Default: O°C
6.2 Sensor calibration
Caution
Settings are only necessary in special cases at the time of initial com-
missioning by the specialist. Incorrect measurement values can lead to
unpredictable errors.
Starting the commissioning help guides you in the correct order through the basic set-
tings necessary for commissioning, and provides brief descriptions of each parameter
in the display.
Pressing the “esc” key takes you back to the previous value so you can look at the se-
lected setting again or adjust it if desired. Pressing the “esc” more than once takes you
back to the selection mode, thus cancelling the commissioning help. (see also E.2).
6.3 Commissioning
Caution
May only be started by a specialist during commissioning! Observe the
explanations for the the individual parameters in these instructions, and
check whether further settings are necessary for your application.
