EH-105
OPERATING INSTRUCTIONS:
Measured value outside of sensor' range:
Indication of sensor defect:
Each sensor has its own typical range. (E.g., 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 at the sensor's measured value to indicate whether the value
is above or below the range.
If there is a sensor defect the controller gives an alarm (see p. 18) and ”err” will appear
in place of the measured value.
The controller can be connected to 18 different measurement data at the same
time (6 NTC measurements, 5 transmitter measurements and 7 digital outputs) If
a measurement is reserved for alarms or for a free temperature measurement, it
can be labeled accordingly. Measurements can be taken into use or removed
from use in the maintenance mode (see p. 42-43).

Also, the state of the voltage controlled (0…10V or 2…10V) actuator can be seen on the
measurements display. Measurement info can also be read through the bus interface or
a GSM.
Only the measurements connected to the controller appear on the display.
