Browsing through measurements:

Every sensor has it's own typical range. (Eg. outdoor sensor 50...+ 50 C).
If the sensor's measured value is outside of this range, a - or + character will
appear on the measurements display in place of the sensor's measured
value to indicate whether the value is above or below the range.

If there is a sensor defect the regulator gives an alarm (see p. 17) and "err"
will appear in place of the measured value.

The regulator can be connected to 14 different measurement data at the
same time (11 NTC measur 3 digital inputs).Measurement data can
also be read through the bus. Also the position of the voltage controlled
(0...10V or 2...10V) actuator can be seen. Measurements 6 and 11 can be
used to indicate external alarms (additional information on alarms page 17)
ATTENTION!

Only the measurements connected to the regulator

appear on the display.
