Measurement values
1. - Measurement values
Caution
If “--” appears on the display instead of the measurement value, then there may be a defective
or incorrect temperature sensor. If the cables are too long or the sensors are not placed
optimally, the result may be small deviations in the measurement values. In this case the display
values can be compensated for by making entries on the controller. Follow the instructions
under „6.7. - Sensor calibration“ on page 43. What measurement values are displayed
depends on the selected program, the connected sensors and the specifi c device design.
2. - Statistics
The menu “2. Statistics” is used for function control and long-
term monitoring of the system.
The menu is closed by pressing “esc” or selecting “Exit

Caution
For analysis of the system data it is essential for the time to be set accurately on the controller.
Please note that the clock does not continue to run if the mains voltage is interrupted, and must
therefore be reset. Improper operation or an incorrect time may result in data being deleted,
recorded incorrectly or overwritten. The manufacturer accepts no liability for the recorded data!
